  • Patent number: 4892760
    Abstract: An apparatus for applying a coating composition to one side of each of several surface type fastener tapes in order to establish the positive anchorage of interengageable hooks or loops on the other side of the tape. Included is a coating roller partly dipped in the coating liquid in an open top receptacle and extending across the fastener tapes traveling in parallel spaced relation to one another. Held against the surface of this coating roller, a doctor blade has several recesses defined in its scraping edge so as to be in register with the fastener tapes traveling in contact with the coating roller. Thus the doctor blade is effective to scrape off the coating liquid only from those parts of the coating roller surface which do not make contact with the fastener tapes, thereby precluding the possibility of the coating liquid from flowing over the selvages of the fastener tapes onto the other sides of the tapes carrying the hooks or loops.
