FIELD: mechanical engineering. SUBSTANCE: device has carrying part which is secured to the transporting mechanism, e.g. to closed-loop chain conveyer. Movable member made of a wear resistance material is secured to carrying part in such a way as carrying part can hook the rear edge of the sheet to be fed during the forward trow. Movable member bears on at least one resilient intermediate spring spacer which affects carrying part Movable member has resilient bushing made of a metal. Both ends of the bushing bear on intermediate spacers made up as electrically insulating ring washers and, through them, on shaft secured to carrying part of clamp. As a result, when sheet is fed to a welding apparatus the rate of feeding significantly increases. EFFECT: increased rate of feeding and excluded damages of sheet. 6 cl, 13 dwg
