Pneumatic Grips

Pneumatic Grips are ideal for testing sheet materials including films, tapes, paper, textiles, nonwovens and tissue. There is a wide range of capacities available. There are different widths 1″, 2″, 3″ grip inserts available, and different surfaces (smooth, serrated, rubber covered). Pneumatic operation makes sample insertion faster and easier than manual grips and ensures a contact uniform pressure.

The most popular gripping solution is a set of vise style clamps. These offer versatility and can be configured to meet the needs of most tensile/pull applications for flat, sheet material such as paper, paperboard, plastic film, textile, nonwovens, foil, tapes, flexible packages and the like. The vise clamps can be supplied to operate mechanically, pneumatically or hydraulically. Depending on the material the jaws are available with surface textures such as smooth, rubber coated, serrated and wave pattern. The selection of the jaw surface will depend on the material being tested.

When choosing a set of vise grips it is important to understand that the published clamping force is not always the maximum tensile force that these grips can achieve. The maximum tensile force that the grips can achieve is a combination of the jaw size, material COF and rated clamping force. It is recommended to select a vise grip with a clamping force rated above the anticipate maximum tensile strength of the material.
