Spine strip stock material, being withdrawn from a supply reel, is cut into pieces of the desired length and the pieces are subsequently fed into positionally accurate contact with cover boards which are moving on a conveying system. High cutting and feeding accuracy are achieved by a servomotor control system which, in response to sensing the motion of the cover boards, stops the infeed of the stock material, clamps and cuts the stationary stock material, feeds the cut spine strip pieces to a waiting position and then moves the pieces from the waiting position into contact with the cover boards.
