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.

Abstract: Air bubbles which are entrapped within the cells of an engraved applicator roller are displaced from the cells by wiping the surface of the engraved applicator roller with the bristles of a brush. An elongated brush mounted on a doctor blade head projects into a doctor blade reservoir. The bristles of the brush are disposed for wiping engagement against the engraved surface of an applicator roller which is wetted by liquid coating material. As the engraved applicator roller rotates in contact with the liquid material in the doctor blade reservoir, the bristles of the brush puncture the entrapped air bubbles and sweep the entrapped air away from the cells. The sweeping action of the bristles induces a relatively low pressure condition within the cells, which promotes the flow of liquid material into the cells.
