Gripper Feed Clamps

Basic principle of Zehnder & Sommer grippers

EZ grippers clamp the material from below. This clamping function has the advantage that, thanks to the slight sagging of the strip when the movable pliers are retracted, the strip is hardly touched and the surface of the punching strip remains largely undamaged. Applies to all models, with the exception of older models that are no longer available.

In addition, the technology is completely integrated into the lower part of the pliers and the upper part of the pliers can be variably adapted to the requirements of the materials.

Gripper12

Features

• Pneumatic clamping from below
• Max. 1 mm clamping or intermediate air lift
• Standard pliers suitable for materials up to 1 mm thick.
• Thicker materials require additional inserts in the side section or special clamps.
• Standard clamps made of flat steel. Clamping surfaces can be adapted to the shape and sensitivity of the material with different shapes, finishes and coatings: e.g. ribbed surface, nylon or plastic, etc.

Gripper25

Features

• Pneumatic clamping from below
• Max. 1 mm clamping or pilot release
• Standard gripper suitable for materials up to 4 mm thick.
• Thicker materials require additional inserts in the side section or special grippers.
• Standard gripper made of flat steel. Clamping surfaces can be adapted to the shape and sensitivity of the material with different shapes, finishes and coatings: e.g. ribbed surface, nylon or plastic, etc.

Innovations compared to Gripper12

• Spring system installed so that the springs are free when changing the clamp heads (no unwanted falling out)
• Special clamps for parallel guidance of several materials (e.g. 2 - 5 wires for contacts)
• Attachment of longitudinal guides to prevent material from buckling
• Standard pliers allow easy insertion of inserts that can be produced at short notice for different applications (3D printing also possible for small series)

Gripper G

• pneumatic two-finger clamps

Gripper Q

• Special gripper for linear feeders and transfer systems

Advantages:

• Based on the proven EZ-gripper system
• Faster cycle times
• Higher, adjustable clamping force
