JWIS Grip Chains: Reliable high performer!

Gripchains with wear-resistant and corrosion-resistant clamping elements are used for gripping, pulling and transporting thin-walled materials with large surface areas. For example, in the packaging industry, the food industry and the electrical industry as well as in the production of circuit boards or in the metal processing.

Positioning

Delicate materials such as foil packaging, thin sheet metal , synthetic materials and other plate-type, hard materials must be handled carefully. Material being conveyed should not be damaged during transporting, positioning, feeding, pulling in and pulling out, punching, welding, filling, coating, cutting, stretching, shaping or sealing.

iwis grip chains with clamping elements provide an optimal feed of materials due to their special technique of pivoting grippers. The conveyed material can be precisely positioned by secure clamp. Due to the different spring forces, a variety of materials can be gently clamped. Chain and clamping elements are standardly corrosion-resistant, wear-resistant and equipped with food-safe initial lubricant.

More space for the plastic film through the optimization of the gripper functioning

Current solution

Current solution

  • Not enough space for foil insertion
  • Point load application on the foil may lead to foil rupture and noise exposure
  • Foil deformation possible at gripper element
    Advantages of the iwis solution

    Advantages of the iwis solution:

    • Accurately fitting of the gripper in the groove
    • Better retention force depending on plastic film
    • Optimized functional safety and hygiene through burling plate
    • Better foil insertion through more free space
    • Foils do not twist
