Grip chains for precision feeding, transport and positioning
Chain manufacturer iwis presents grip chains. These chains have wear- and corrosion-resistant clamping elements that ensure safe and reliable feeding, transport and positioning of thin-walled materials with a large surface area.
The clamping elements allow the chain to grip and hold thin-walled materials with large surface area, such as films. Different levels of spring force allow a wide range of materials to be gently gripped and securely held. Conventional grip chains often have the drawback that the clamping elements do not provide enough space to insert the film. They also apply a point load to the film, which can cause the film to deform at the gripper or even to rupture. They are also noisy in operation. The gripper of the new grip chains from iwis fits into its groove very accurately and therefore offers a better retention force. More free space in the foil insertion area allows an improved foil feed and the foils do not twist or deform at the edge of the gripper element. This design also reduces noise emissions. The grip chains also feature burled plates, which ensure a reliable operation and optimum hygiene.
High-performance grip chains from iwis have an outstanding wear resistance. Being optimally pre-stretched, the chains exhibit only a minimal initial elongation. Being highly rigid, they can also be used in long machines. Identical chain lengths within the selected tolerance range ensure excellent running characteristics in both synchronous and parallel operation. The basic chain versions are chemically nickel-plated. Maintenance-free Megalife versions are also available. The recommended maximum running speed is 2 m/s for the ½ inch grip chain and 0.6 m/s for the 5/8 inch version. For higher running speeds, a different control geometry is required.
