procedure and device for stepwise forflyttning of several major platar of different size

摘要

Method and apparatus for successively conveying large metal plates of different sizes to a particular position where an operation such as welding a reinforcing element thereto can be performed. The plates of different sizes may be gripped at points on the front and rear ends in line of their movement with one side edge engaged by guide rollers on a side of the conveyor track, and the distance between the line of gripping points and the edge of the apparatus is so determined as to permit conveyance of plates of a range of different sizes to be conveyed to the desired position without misplacement due to twisting.
