<p>The present invention relates to a method for manufacturing adhesive tapes (1, 2) from an elongated material web (3) which is coated with an adhesive (6, 8) at least along the side margins thereof, and which has a non-adhesive, straight band (7) extending centrally in the direction of the longitudinal axis of the web. In accordance with the invention the web (3) is divided longitudinally by means of two wave-shaped line-cuts (10, 11; 10', 11') which are positioned so that the line-cuts will not intersect one another within the region of the non-adhesive band (7), such that the wave crests of a first line-cut (11; 11') and the troughs of a second line-cut (10; 10') lie within the confines of the non-adhesive band, whereas the wave troughs of the first line-cut (11; 11') and the wave crests of the second line-cut (10; 10') lie externally of the non-adhesive region. The web is also divided transversely by means of line-cuts (12; 12') which extend transversely to the long axis of the web, from the centre of the crests and troughs of the two longitudinally extending line-cuts (10, 11; 10', 11'), which lie externally of the non-adhesive band, to the side edges of the elongated web. The invention also relates to a fastening tape (1, 2) manufactured in accordance with the method.</p> |
