Abstract
A header tape for a curtain or the like comprises loop regions for use with a hook and loop fastener. The loop regions cause the header tape to be thicker in these regions. The loops of the loop regions will be pulled out under constant use unless the back of regions are coated by an adhesive. Using the difference in thickness between loop regions and the non-loop region, intermittent coating can be achieved by feeding the header tape through a small gap between a press roller and a coating roller. The gap is chosen so that it is smaller than the thickness of the loop regions but larger than the thickness of the non-loop region of the header tape.
