ABSTRACT:
A sheet stock feed line in which sheet stock is leveled and fed by a leveler to a feeder and each time the feeder feeds the sheet stock by a predetermined length, the feed by the feeder is stopped for working the sheet stock. While the feed by the feeder is stopped, the leveler feeds the sheet stock at a very low feed rate to form a loop of the sheet stock between the leveler and the feeder. When the loops reaches a predetermined size, the feeder resumes the feed of the sheet stock and the leveler is controlled so that its feed amount follows that by the feeder.
