ABSTRACT:
A large rectangular plate is subdivided into small rectangular sections in a system wherein the plate is fed stepwise in a main direction through an upstream shear while the downstream end portion of the plate is seized immediately downstream of the shear with each advanced step. Between the advanced steps the end portions are sheared off and then displaced in the main direction to the upstream end of a conveyor where they are deposited one after the other. The conveyor displaces the sheared-off end portions until each one is positioned above a respective aligner spaced apart in the main direction. The conveyor lowers these sections onto the aligners and the aligners then align them perfectly perpendicular to the main direction. The aligned and sheared-off end portions are then pushed jointly in a transverse direction perpendicular to the main direction stepwise to a downstream shear while they are supported and pneumatically seized at their downstream ends immediately downstream of the downstream shear. The downstream shear then cuts off these downstream ends which are displaced to a collection location and deposited there.
