Claims5
An apparatus for making an adhesive tape, the apparatus comprising:
- a supply for feeding a ribbon-shaped textile substrate strip of thermoplastic fibers in a longitudinal feed direction along a path;
- a coater downstream of the supply along the path for applying a strip-shaped adhesive coating to at least one face of the substrate strip;
- an ultrasound or laser device provided between the supply and the coater and movable in three dimensions, transversely and longitudinally of the longitudinal feed direction and also toward and away from the moving web for forming longitudinal and transversely extending rows of perforations and/or cut edges in the moving substrate strip;
- and
- a cutter downstream of the coater for cutting the perforated/cut and coated strip into a plurality of longitudinally extending tapes.
