Abstract
The invention provides a device for positioning sheet blanks (2, 3) in an installation for the continuous butt welding of the sheet blanks (2, 3) by means of a laser beam. The device comprises, on one hand, a conveyor table formed by an alternating arrangement of rails (11) having balls and bands (12) provided with projecting studs (13) evenly spaced apart and, on the other hand, friction means (15) adapted to be applied on the upper face of the sheet blanks (2, 3) and impart to the sheet blanks a movement in translation which is substantially perpendicular to the direction of feed of the sheet blanks (2, 3).
