Abstract (en)

[origin: EP0949375A2] During transfer of the strip (2) of the fibrous band (1), at the region of transfer (5), suction is applied. Suction is also applied in the separation region (6) immediately following. An Independent claim is included for equipment as described, in which the region of suction can be moved with respect to the transition region, preferably by turning. PREFERRED FEATURES:- Especially with bands (3,4) first meeting in the transition zone (5), the transferred band (4) is subjected to suction just before the transition. Air is blown against the materials from the opposite side. In the equipment, separate suction zones may be included; further variants are described. The suction zone is supplied with compressed air. It can be formed by a rotating perforated roller. Sliding surfaces seal the edges.
