Abstract
Device for guiding and feeding at least two sheet blanks previously brought edge to edge to form a joint plane, of the type including two units for supporting and feeding the sheet blanks in the direction of a high energy density beam disposed on each side of the joint plane and movable in synchronism with each other. Each supporting and feeding unit includes at least one lower series of carriages or at least one upper series of carriages, these carriages being articulated together in a vertical plane and movable in a direction parallel to the joint plane on a runway constituting a reference plane. Each carriage carries at least one shoe movable relative to the respective carriage in a direction perpendicular to the joint plane. The shoes of at least one of the two series of carriages cooperate with a device exerting a lateral pressure on the edges to be welded of the sheet blanks by a displacement of the shoes in a direction perpendicular to the joint plane.
