ABSTRACT:
Apparatus to move rectangular blanks from a receiving station to a loading station position. The apparatus has a support framework and a driven track to move the blanks from the receiving station towards the loading station. A feed station receives the blanks. Alignment devices in the feeding station position a blank. A blank is prevented from moving along the feed station while a further blank is being aligned. A separator separates the stacked blanks and a scanner system detects blanks of a predetermined width. A magazine stores blanks detected by the scanner system. Blanks detected by the scanner system can be moved from the track to the magazine. An end stop is on the track and a transfer device, over the track, before the end stop, receives a course of blanks. A scanner system, remote from the end stop, determines how a partially formed course of blanks should be completed. A transfer device removes a blank from the magazine to the track if the last mentioned scanner system indicates a blank of predetermined width is required to complete the course. A further scanner indicates a full course of blanks beneath the second transfer device and controls the transfer of a course of blanks to the loading station.
