Introduction

An automatic, digital tear tester equipped with an optical encoder for measuring the angular position of the pendulum during tearing and converting this measurement to tear strength units. A large, full-color touchscreen display with intuitive, easy-to-use software provides a revolutionary new approach to testing and data review.

Elmendorf Tear testing determines the force required to continue the tearing of an initial cut in sheet materials such as paper, plastic film, textile and non-wovens.

Easy-to-use touchscreen interface

The model 83-76 features a dynamic digital touchscreen user interface that allows for complete user interactivity and instrument control.  The 7” full color screen displays a resolution of 800×480 pixels and provides optimal viewability at almost any angle.

Software features include custom test and sample IDs, data export via RS-232 and USB, maintenance/diagnostics menus and more.

Calibration of the pendulum is accessed through the touchscreen interface and is completed automatically in a few simple steps.

Pneumatic clamps

Simple, two-button operation of the pneumatic clamp and swing operations ensures efficient and repeatable measurements of tear strength.  A built-in cutting blade prepares samples for testing.

Introduction

The Internal Bond™ Tester is designed to determine the internal bond strength of a variety of Paper and Board materials according to TAPPI T 569 and ISO 16260. The instrument design is based on a falling pendulum which creates a high speed impact on a paper specimen. The paper specimen is sandwiched between two double-coated tape substrates. The pendulum impact measures the total energy required to delaminate the internal fibers of a specimen in a “Z” type direction into two plies.

An automatic sample preparation station 
(Model 80-30) is available which allows five specimens to be accurately pressed and cut simultaneously. The prep station includes a safety enclosure over the cutting blades, eliminating the use of box cutting knives to separate the individual test specimens.

• Storage and editing of up to 100 readings including average and standard deviation
• Selectable units (ft.lb/in², J/m² and kg•cm)

32-76e Coefficient Friction/Peel Tester

Introduction

Crease and Board Stiffness testing is useful to industries of carton board, paper, printing and packaging. The relationship between board stiffness and crease recovery (spring back) is an important factor in the performance of cartons on high speed packaging machines and in manual folding. It is crucial to have the creases in boards correct and uniform. The crease recovery (spring back) can result in forces, which distort the carton or cause stresses to be applied to closures, which reduce their effectiveness.

Board stiffness is determined by bending a 2 in (50mm) length of board through a 15° angle. Crease recovery is determined by holding a formed crease at 90° and measuring the recovery force after 15 seconds. This instrument measures the bending resistance of the board and evaluates commercially formed creases.

With interchangeable jaws to test square corner packs and round corner packs. The sample is griped in jaws and rotated through a set angle, the force transmitted through the sample is measured. To assist in accurate cutting of sample specimens, a Crease and Board Stiffness cutter is included.
