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 and...

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 resistant,...

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 ... • lease...
