Grip Chains Problem/initial situation: Reliable feeding, transporting and positioning of thin-walled materials with a large area. Our solution: iwis high performance chains with wear- and corrosion-resistant clamping elements! Key features • iwis high performance chain with excellent wear resistance • Marginal initial elongation due to optimal pre-stretching • High rigidity enables applications also in long machines • Basic chain chemical nickel plated • lawless operating parallel as well as synchronously F running chains due to practically identical chain lengths • ll chains are provided with reliable, high quality A initial lubrication, approved for use in the food industry • iffering levels of spring force allow an extremely wide range D of materials to be gripped gently • Complete chain solution – ready-to-install • Delivery in 50 meter reels or in customized chain lengths • Recommended max application speed is 2 m/s

Technical features Technical features • ingle and duplex chain 1/2 x 5/16 inch S to DIN 8187-1/ISO 606 • ingle chain 1/2 x 5/16 or 5/8 x 3/8 inch S to DIN 8187-1/ ISO 606 • ripper designed as a flat clamp G • pecial design with button grip elements S • etaining force is dependent on material conveyed R and spring design – differing number of coils and wire spring diameters obtainable • Gripper as a flat head “Flat clamp” Grip chains “Button” Grip chains • he gripper opens by running against a control disc T (e.g. chain wheel hub) which causes it to swivel out of the way to the outside •...

New iwis Grip chain – a complete solution Technical features • 106 standard chain also available without M attachments • Clamp and spring made of corrossion resistant steel • Chain is chemically nickel-plated • vailable with long-lasting lubrication A or with lubricant for food use Ave. foil retention force (N) These are max. values for the opening stroke. Lower opening strokes will increase life expectancy of the spring. Note: All facts ascertained by laboratory tests. Differences to real applications are possible. • ptimization of the gripper Chain M106 with attachO ment 202.6 on one side...

Optimization of the gripper functioning More space for the plastic film Current solution • ot enough space for foil insertion N • oint load application on the foil may lead P to foil rupture and noise exposure • oil deformation possible at gripper element F iwis solution Advantages • ccurately fitting of the gripper in the groove A • Better retention force depending on plastic film • ptimized functional safety and hygiene O through burling plate • Better foil insertion through more free space • Foils do not twist Details of the gripper functioning • Clamp is being made out of corrosion...

The sprockets for our new gripper chain are really simple! • procket design is based on a two part assembly. S One part is a sprocket nearly the one side hub sprocket like catalog. The second part is a control disk • his part must be hardend because it is in contact T to open the gripper • The two parts are assembled with press fit • s smallest sprocket for this application A we advise 14 teeth • or a better chain running we suggest more than F 19 teeths for the sprocket • lot of adaptations are possible, for example plumA mer blocks, keyways, threads, special diameters, surfaces ... •...

Available chain guides made of plastic Slide rails from ultra high molecular high density polyethylene (PE-UHMW)1000 with a regenerative component. This proven quality is characterised by its outstanding sliding properties, abrasion resistance and mechanical values. Special custom-made guides are available on request!
