Abstract

A method and apparatus for assembling blinds includes a punching and cutting station, an outfeed station and a lacing stating having a plurality of lacing towers. A guide cable extends between adjacent lacing towers for guiding transported slats. A pivoted backstop at a downstream end of the lacing station yieldingly arrests the motion of incoming slats. The outfeed station of the apparatus includes a continuously driven outfeed drive roller and an opposed pinch roller which may be selectively urged against the drive roller so as to drive a slat out of the outfeed station. Each lacing tower of the apparatus includes a spring-biased spreader which provides longitudinal tension to a tape ladder while preventing longitudinal stringers of the ladder from converging upon each other. The method of the present invention includes operating the apparatus to automatically learn the selected length and arrangement of the blind and to subsequently automatically manufacture a blind to those specifications.
