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.
- Wide product range
- For transporting sensitive materials
“1-tip” Grip Chains
Technical features Version A
- Single and duplex chain 1/2 x 5/16“ acc. to ISO 606
- Gripper with 1 tip, special designs on request
- Retention force is dependent on material conveyed and spring design – different number of coils and wire spring diameters available
- The gripper opens when it runs against a control disc (e.g. sprocket hub), causing it to swivel away outwards
- Food-grade initial lubrication
- Sprocket designs on request
“2-tip” Grip Chains
Technical features Version B
- Single and duplex chain 1/2 x 5/16“ acc. to ISO 606
- Gripper with 2 tips, special designs on request
- Retention force is dependent on material conveyed and spring design – different number of coils and wire spring diameters available
- The gripper opens when it runs against a control disc (e.g. sprocket hub), causing it to swivel away outwards
- Higher retention force in comparison with 1-tip grip chain
- Food-grade initial lubrication
- Sprocket designs on request
“Flat clamp” Grip Chains
Technical features Version C
- Single and duplex chain 1/2 x 5/16“ acc. to ISO 606
- Gripper with flat clamping surface
- Retention force is dependent on material conveyed and spring design – different number of coils and wire spring diameters available
- The gripper opens when it runs against a control disc (e.g. sprocket hub), causing it to swivel away outwards
- Gentle handling of materials
- Low transmission forces
- Sprocket designs on request
“Button clamp” Grip Chains
Technical features Version D
- Single chain 1/2 x 5/16“ or 5/8 x 3/8“ acc. to ISO 606
- Rotationally symmetrical gripper element
- Extremely flat button clamp
- Retention force is dependent on material conveyed and spring design – different number of coils and wire spring diameters available
- iwis patent (spring without additional fixing elements)
- Does not swivel away outwards when opened
- Sprocket designs on request
Grip chain with clamp E
Technical features Version E
- Optimization of grip chain M106 with attachment 202.6 on one side and delivery as a complete solution with gripper system consisting of clamp, burled plate and spring
- Clamp and spring made of corrosion-resistant steel
- Chain is chemically nickel-plated
- Available with long-lasting lubrication or food-grade lubricant
- Alternative: M106 standard chain also available without attachments (clients may fit their own grippers)
- Springs with optimised surface structure
Grip chain with clamp F
Technical features Version F
- Single and duplex chain 1/2 x 5/16“ acc. to ISO 606
- 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
Grip Chain 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.
- iwis provides complete, ready-to-install solutions!
