Sensitive materials, such as packaging foils, thin-walled sheet metals, plastics and other hard sheet and strip materials must be handled gently during processing to avoid damaging the conveyed materials in transport, positioning, drawing in, punching, welding, filling, coating, cutting, stretching, forming or sealing. Iwis grip chains with clamping elements feature a special swivel arrangement that ensures optimised feeding and precise positioning of the conveyed products. The spring force can be adjusted to allow gentle gripping of a wide range of materials. Chain and clamping elements are wear-resistant, corrosion-protected and pre-lubricated with food-safe lubricant as standard.
The grip chains are available as simplex and duplex chain according to DIN 8187-1. The grippers have either one or two tips; on request special gripper designs are also available. Because the applied holding force depends on the conveyed goods and the spring type used in the grippers, the chains are supplied with different numbers of turns and spring wire diameters. A special type with cup grippers for foil transport is also available.
In addition to grip chains, iwis provides a full product range for all drive and conveying applications. The iwis group’s programme for industrial applications comprises precision and high-performance roller chains, conveyor chains, maintenance-free and corrosion-resistant chains, accumulation chains, special-purpose conveyor chains, flyer chains, flat-top chains and modular belts, chains for agricultural machinery, as well as timing drive systems for the automotive industry.
