Grip Chains
Grip chains with wear-resistant, corrosion-proof clamping elements are used for gripping, pulling and transporting thin-walled materials with large surface areas. Sensitive materials such as plastic film packaging, thin sheet metal, plastics and other hard sheet materials require careful handling to prevent damage during transport, positioning, feeding, pulling in or out, stamping, welding, filling, laminating, cutting, stretching, forming or sealing.
iwis grip chains with clamping elements provide an optimal feed of materials. The special pivoting gripper mechanism ensures high-precision handling and precise positioning of the conveyed material by secure clamping. Variable spring forces allow gentle clamping of a wide variety of materials. Chain and clamping elements are corrosion-protected, wear-resistant and treated with food-grade initial lubricant as standard.

- Complete gripper element
- Gripper element with a continuous sharp-aged gripping flange
- Retention force is dependent on material conveyed
- Clamp and spring made of stainless steel spring steel
- Due to a special geometry of sprockets used, the gripper opens with a slight sideways movement
- Food-grade initial lubrication
- Sprocket designs on request
Version G
- Simplex chain 5/8 x 3/8" acc. to ISO 606
- Rotationally symmetrical gripper element
- Extremely flat button clamp
- Does not swivel away outwards when opened
- Thicker diameter, lower pressure

- Rotationally symmetrical gripper element
- Extremely flat button clamp
- Does not swivel away outwards when opened
- with finger and parts protection
- Improved contact geometry of the grip element minimizes wear on the opening contours.
- Side protection tabs prevent packaging material from unintentionally entering the functional area of the grip element and spring, reducing the risk of malfunctions in the system
- Protection tabs enhance occupational safety by minimizing the risk of pinching hazards.
Version I
- Simplex chain 1/2" x 5/16" according to ISO 606
- Gripper with 4 tips
- Clearance-free gripping of the film
- Extremely wear-resistant grip elements with specially designed holding geometry
- Uniform tension distribution in the film
- Highest holding force compared to grip chains in the ½" segment
- Available as standard in ML version
Product highlights
- iwis high-performance chains with excellent wear resistance
- Minimal initial elongation due to optimum pre-stretching
- High rigidity also enables applications in long machines
- Basic chain versions are chemically nickel-plated / MEGAlife maintenance-free versions are available on request
- Identical chain lengths (within the selected tolerance range) ensure excellent running characteristics in both synchronous and parallel operation
- Differing levels of spring force allow an extremely wide range of materials to be gripped gently and held securely
- Chains with restricted length tolerances can be produced
- Recommended maximum running speed:
- → 2 m/s for the 1/2“ grip chain
- → 0.6 m/s for the 5/8“ grip chain
- Different control geometry is required for higher running speeds.

Grip chains: reliable top performers!
Grip chain versions need to be as diverse as the applications for which they are used, so iwis has developed a wide range of grip chain products. Grip chains with one tip, or two tips for added gripping power, are mounted on an ISO 606-compliant simplex or duplex 1/2 x 5/16" chain. Grip chains feature a flat clamping surface to ensure gentle material handling. On grip chains with button clamps – patented by iwis – the extremely flat clamp does not swing outwards when opened.
As well as various clamp designs, iwis also provides complete solutions with a clamping system consisting of clamp, burling plate and spring. The grip chain with clamp design F ensures that material is gripped safely but firmly. Actuated by the special sprocket geometry, the clamp opens with a slight lateral movement. iwis supplies matching sprockets for all grip chains with various control disc diameters.
