Abstract
An apparatus capable of simultaneously coating one side of each of several surface type fastener tapes or the like traveling longitudinally in coplanar, parallel spaced relation to one another. For simultaneously coating two fastener tapes a pair of terminal coating units and one intermediate coating unit are arranged alternately with the fastener tapes. Each fastener tape travels with its opposite longitudinal edge portions slidably engaged in recessed guideways defined in the terminal and intermediate coating units. A coating material is supplied through passageways in the coating units onto the surfaces of the fastener tapes traveling therebetween. Mounted to the coating units so as to extend across the fastener tapes, a doctor blade has its scraping edge held against the surfaces of the tapes. The fastener tape guideways in the coating units all decline from their upstream toward downstream ends with respect to the traveling direction of the tapes, so that the coating material collects in the spaces bounded by the tapes, coating units and doctor blade. The doctor blade creates a coating of constant thickness on each fastener tape as the latter travels therepast.
