The Taber Linear Abraser incorporates a horizontal arm that reciprocates in a linear motion. Attached to the end of the arm is a precision bearing spline shaft that creates a 'free-floating' test system and permits vertical movement. The test attachments are affixed to the bottom of the spline shaft and a weight support is mounted to the top. As the horizontal arm strokes back and forth, the test system raises or lowers vertically as the test attachment follows the contours of the specimen. A laser alignment guide assists with specimen set-up to ensures the abradant travels over the desired area.

Adjustable settings enable the user to select the speed, stroke length and test load. The Linear Abraser includes six preset speed buttons, along with the ability to adjust the speed from 2 to 75 strokes per minute. Eleven stroke lengths are standard ranging from 0.2 inch to 4.0 inch. 

Taber Linear Abraser 5750
The base load of the "free-floating" test system is 350 grams and consists of the test attachment; spline shaft; and weight support. Three 250g weight discs are supplied with the instrument and optional weight discs ranging from 10 to 250 grams can be added to the weight support to increase the test load to approximately 2100 grams. Optional accessories can be also be used to decrease the load. For example, an 150mm aluminum spline shaft and plastic Wearaser Collet Kit can bring the minimum load on the sample to as low as 60 grams. Taber's Linear Abraser is programmable to 999,999 cycles, but caution must be used as the abradant may wear prior to the end of the test.
The Wearaser® collet assembly is supplied with each Taber Linear Abraser, along with CS-10 and H-18 Wearaser abradants. The size and shape of a pencil eraser, the Wearaser is made using the same high quality Taber abrasive media found in our Genuine Taber abrading wheels. This permits the use of equivalent abrasive materials with the Linear Abraser as well as Taber's Reciprocating Abraser and the Taber Rotary Platform Abraser.

The Multi-Head Attachment (sold separately), incorporates an additional spline shaft, permitting two tests to be performed simultaneously with the Linear Abraser.

With the diversity of products that can be tested with the Taber Linear Abraser, it is up to the end-user to determine a suitable clamp or fixturing device appropriate to their product. Click here for additional information on specimen mounting available from Taber Industries.

The TABER® Reciprocating Abraser (Abrader) - Model 5900 is a test apparatus similar to the instrument described in test method ISO 1518. Ideal for flat surfaces, this tester can be configured with optional attachments to evaluate the relative resistance or susceptibility of a material surface to physical damage such as wear and abrasion, rub, scratch, mar, gouge, scrape, plus others.

The Taber Reciprocating Abraser includes a counterbalanced arm which pivots on an adjustable height gantry system. The counterweight allows the user to balance the test arm, ensuring precise test load set-up regardless of the weight of the attachment. Incorporated at the end of the arm is a tool holder to which optional attachments and weights may be secured. A sliding specimen platform moves in a horizontal, reciprocating motion under the stationary tool holder.

Test parameters such as stroke length (6 - 155mm), speed (3 - 75 cycles per minute) and load (1N - 24N maximum, with included weights of 1N, 2N, 2.5N, 5N, 10N & 24N) are adjustable so optimal settings for each material can be established.

To expand test loads, optional auxiliary weights are sold individually and available as 50g, 100g, 150g, 200g, 500g, 1000g, 2000g, 2400g and 5000g. In addition, an optional weight support may be affixed to the top of the tool holder. This permits using auxiliary weight discs originally intended for Taber''s Linear Abraser 5750 (10g, 20g, 50g, 75g, 100g, 150g or 250g).

Product Details:

The TABER® Heavy Duty Linear Abraser - Model 5800 is used to evaluate material properties of products with a rugged, durable surface finish that require an increased testing load or longer stroke length. Supplied with the 2" diameter Universal Attachment and Scotch-Brite™ scouring pads, the Heavy Duty Linear Abraser is ideal to measure a coating''s resistance to scrubbing with an abrasive scouring pad. A popular application includes evaluating non-stick coatings used on cook / bake ware

Description
Similar to Taber''s Linear Abraser, a test attachment is secured to the bottom of a vertical spline shaft and accessory weights may be placed on a weight holder affixed to the top. A precision bearing on the spline shaft creates a "free-floating" test system. As the test arm moves in a linear motion, the "free-floating" system will raise or lower as the test attachment follows the contours of the specimen being tested - curved or flat.

The base load of 500 grams consists of the test attachment, spline shaft and weight holder. Accessory weights of 1000, 2000 and 4050 grams are included and can be added to the weight holder to increase the test load. With a high torque motor, the Heavy Duty Linear Abraser can accommodate a maximum testing load of 20 lbs. (weight sold separately).

Other features of the Heavy Duty Linear Abraser include a slotted roller channel allowing stroke length adjustments up to 318mm (12.5 inch); five preset speeds including 15, 30, 37, 45, and 60 cycles per minute; and an integrated T-slot table for securing specimens during testing.

With interchangeable attachments, the Heavy Duty Linear Abraser can also be configured similar to the Linear Abraser to evaluate the relative resistance or susceptibility of a material surface to wear and abrasion, scratch, gouge, scrape, rub, and more. In addition, the instrument can be used for both wet and dry testing. To increase test output, an optional second test arm kit may be added to perform two tests simultaneously.

Evaluation
Tests conducted with the Heavy Duty Linear Abraser using the Scotch-Brite™ scouring pads are normally performed until the surface coating has been worn down to the substrate material or a portion thereof (breakthrough). Alternatively, tests can be run for a predetermined number of cycles (e.g. 10,000) with mass loss used as the end point.

Product Details:

The Taber® Fabric Stiffness Tester - Model 112 provides a quick and accurate method of determining stiffness properties such as flexural rigidity of most textile fabrics according to internationally recognized test standards such as ASTM D1388. Ideal for testing textile fabrics (e.g. woven; layered; pile; knitted; napped), this instrument has been utilized to evaluate the stiffness properties of blankets, air bag fabrics, protective clothing, geotextiles, etc. Fabrics may be untreated or treated, including those that are heavily sized, coated or resin-treated. Taber's Fabric Stiffness Tester can also be used to evaluate leather, paper, plastic films, and other flexible sheet materials.
Employing the principle of cantilever bending, a rectangular specimen is supported on a smooth low-friction horizontal platform. A weighted slide is placed over the specimen and advanced at a constant rate. As the leading edge of the specimen projects from the platform, it bends under its own weight. The bend angle indicator can be set at either 41.5° (0.724 rad) or 45° (0.785 rad) below the plane of the platform surface, and includes an easy to read bend angle reference scale with 5° graduations. Once the material flexes enough to touch the bend angle indicator, the test is stopped. Using a scale calibrated in both metric and English units, the length of the overhang is then measured and flexural rigidity and bending modulus can be calculated.

The Fabric Stiffness Tester is available with or without the Hand Crank Speed Control Option. This feature allows the operator to control the rate of speed that the specimen is advanced.

Product Details:

The TABER® V-5 Stiffness Tester - Model 150-B or 150-E is used to evaluate stiffness and resiliency properties of materials up to 10,000 Taber Stiffness Units. This precision instrument provides accurate test measurement to ±1.0% for specimens 0.004" to 0.219" thickness. Materials include paper products, cardboard, plastics, metals, textiles, rubber, wire, tubing, felts and other sheet materials.

Incorporated in the TABER V-5 Stiffness Tester is a bi-directional pendulum weighing system. Providing an accurate and responsive method for measuring small load increments, this system is a critical component for determining material stiffness or resiliency. Nine (9) distinct ranges permit testing of materials that are extremely lightweight and flexible (such as cellophane or thin metallic foils) to items that are very rigid (such as plastics).

For test ranges 2 - 9, specimens are mounted on the Taber V-5 Stiffness Tester using a clamping system. Located on the pendulum, the lower faces of the specimen clamp jaws are exactly on the center of rotation.

Taber Stiffness Testers 150B (left) & 150E (right)
This ensures a constant test length and deflection angle for accurate and repeatable results. Both jaws of the specimen clamp are adjustable, so the test specimen can be positioned precisely in the center regardless of material thickness. Force is applied to the lower end of the specimen by a pair of rollers. The rollers, which are attached to a driving disc located directly behind the pendulum, push against the test specimen and deflect it from its vertical position. The pendulum applies increasing torque to the specimen as it deflects further from its original position. The test point reading occurs when the pendulum mark aligns with the appropriate driving disc mark (7 1/2° or 15°), which points to the stiffness reading on the dial point. The final reading will depend on the range in which the test is being conducted and what scaling factor to use. The instrument outputs the moment load applied to the test specimen in TABER Stiffness Units (g · cm).

Note: The right hand roller includes a ratchet stop mechanism that greatly reduces the potential for inter-operator error caused by over or under-tightening. The travel on the right hand assembly automatically stops when the roller contacts the specimen.

To allow the testing of materials with different stiffness properties, range weights can be applied to the pendulum. For extremely light weight materials, a compensator range weight is mounted to the top of the pendulum. Range weights of 500, 1000 and 2000 "Taber Units" are mounted to the bottom of the pendulum and required for stiffer materials. An optional range weight set of 3000 and 5000 Taber units is required for test ranges 7, 8 and 9.

Range 1 is used with Taber''s optional Sensitivity Range Attachment (also referred to as SR or High Sensitivity Attachment) to test extremely lightweight and flexible materials whose Taber Stiffness Unit value are between 0 - 1. Examples include cellophane, natural fibres and synthetic filaments, tissue paper, metallic foils, films, etc. The attachment includes two parts, the Driven Pins Holder which is secured between the clamp jaws, and the Driving Pins Holder which is mounted to the studs in place of the left and right hand rollers. Both parts include precision pins that are oriented horizontal to the face of the V-5 Stiffness Tester. A specimen 1 1/2" x 1 1/2" is mounted such that the second and fourth pins are above the specimen. As the driving disc rotates, the fourth pin of the Driving Pins Holder pushes down on the specimen while the first pin pushes up. As the sample is deflected, the Driven Pins Holder aligns the pendulum to the appropriate stiffness value. For Range 1, the specimen is only deflected to the right.

The TABER® Rotary Platform Abrasion Tester - Model 5135 or 5155 is commonly referred to as the Taber Abraser (Abrader) or Rotary Platform Dual (Double) Head Tester. First introduced in the 1930''s, this precision built instrument was developed to perform accelerated wear testing. Capable of providing reliable data in a matter of minutes compared to the years that may be required by in-use testing, the Taber Abraser (Abrader) rapidly became the world standard for evaluating abrasion resistance.

Since its inception, the Taber Abraser has been used for quality & process control, research & development and material evaluation. Used to test a wide spectrum of materials, the instrument has been referenced in numerous standards and specifications (including plastics, coatings, laminates, leather, paper, ceramics, carpeting, safety glazing, etc.).

Product Details:

The Taber® Torsional Stiffness Apparatus - Model 108 has been employed to measure the relative stiffness of gloving leathers. Based on the design described in ASTM D2821 (Standard Test Method for Measuring the Relative Stiffness of Leather by Means of a Torsional Wire Apparatus), this instrument is useful in measuring the flexibility and stiffness of a leather or other bendable specimen.

The Torsional Stiffness Apparatus incorporates a torsion head and wire that translate a twisting motion to a 1/2" wide x 4 1/2" long specimen. Mounted to a rigid base and support post, the torsion head includes a dial protractor graduated from 0 to 360°. Made of 0.010 inch diameter tempered stainless steel wire, the torsion wire passes through the center of the torsion head in a loosely fitting sleeve gripped by a friction bearing. A fixed index pointer indicates the degrees of twist introduced to the torsion wire.

Specimens are secured to the Torsional Stiffness Apparatus by two clamps. The upper specimen clamp is fastened to the lower end of the torsion wire and is able to rotate as the torsion wire is twisted. The lower specimen clamp holds the specimen in place which allows the twisting action to occur. To accommodate the twisting action, the lower specimen clamp can slide up or down guide posts mounted to the base.

To operate the Torsional Stiffness Apparatus, the torsion head is rotated in a plane normal to the torsion wire. As the torsion head rotates, the torsion wire twists the test specimen. Mounted to the top of the test specimen upper clamp assembly is an indicator that measures the twist applied to the specimen until the specimen has been twisted 90°.

Taber Torsional Stiffness Apparatus 108
An optional Finger Control Knob provides an ergonomic design that allows for two-hand operation of instrument, permitting a smooth twisting action of the specimen.

The Taber® Crockmeter - Model 418 provides a quick and accurate method to determine the amount of color transferred from textile materials (such as fabric, carpeting, yarn and leather) to other surfaces by rubbing. The Crockmeter has also been employed to perform rub abrasion, scuff and / or mar tests on flat specimens. Plus, it can be used to conduct smudge and smear resistance tests on images produced by a printer or copier. Regardless of specimen material, both wet and dry testing can be performed.

Originally designed to simulate the action of a human finger and forearm, the Crockmeter uses a standard pressure and rubbing motion to provide reliable and reproducible test results. Specimens are positioned on the base of the Crockmeter and held in place with the sample holder. To prevent the specimen from shifting during testing, a sandpaper pad is provided to place under the specimen. A hand crank moves a reciprocating arm a distance of approximately 100mm. The rubbing action is provided by a 16mm diameter acrylic "finger" which moves back and forth in a straight line with each complete turn of the crank. The reciprocating load arm is weighted to provide a constant 9N load on the sample at all times and a mechanical counter keeps track of completed cycles.
