  • the adhesive coating can also be formed by a rubber or plastic brush made of the appropriate material.
  • the guide roller and the fixing roller each with their own coaxial support roller, which extends towards the center of the web, in order to keep surface distortions in the edge area of the web as low as possible and, if possible, only to create the largest possible area so that wrinkles form be avoided.
  • the support rollers of the guide roller and the fixing roller taper conically towards the free roller end and are cambered at the end.
  • the cone angle depends on the material Depending on the type of web, but generally be chosen so that the half cone angle is about 5 ° to 10 °.
  • the guide roller and the fixing roller are preferably each formed in one piece with their support roller. It may also be advisable to make the distance between the support rollers adjustable in order to prevent wrinkles in the region of the support rollers.
  • the web is designated 1, its running direction by the arrow 2.
  • the web 1 is fed in a tensioning machine, of which only the needle chains 3 are indicated, on which the web edges are needled, to the cutting devices generally designated 4, which have the task of providing the edge strips 5 of the needle chains 3 with the needle chains 3 Cut material web 1 so that the product so trimmed is free of needle punctures.
  • the cut off edge strip 5 should be as narrow as possible in order to avoid unnecessary loss of goods.
  • each cutting device 4 has a hold-down roller 27 which overlaps the needle chain 3 and the web 1, furthermore a circular knife 8 on the same side of the web 1 in the direction of travel of the hold-down roller 27, and one on the other side of the web between the hold-down roller 27 and the circular knife 8 lying needle wheel 9, which lifts the edge of the web against the hold-down roller 27 and the circular knife 8 out of the needle chain 3.
  • the needle wheel 9 is provided with a coaxial support roller 10, which extends towards the center of the web, and is cambered at 10.1 at the free end, but is essentially cylindrical in the rest.
