Hold chains with wear-resistant, corrosion-proof clamping components are used for gripping, pulling and transporting thin-walled materials with huge surface areas. Sensitive materials such as for example gripper chain plastic 
film packaging, slim sheet steel, plastics and other hard sheet materials require careful handling to prevent damage during transportation, positioning, feeding, attracting or out, stamping, welding, filling, laminating, reducing, stretching, forming or sealing.
iwis hold chains with clamping elements provide an optimal feed of components. The special pivoting gripper mechanism ensures high-precision managing and exact positioning of the conveyed material by secure clamping. Variable spring forces allow soft clamping of a wide selection of materials. Chain and clamping components are corrosion-secured, wear-resistant and treated with food-grade initial lubricant as standard.
