Abstract: A device for conveying the leading edges of metal strips, belts and sheets to a fixation point on a reel drum for winding thereon includes a carriage which is movable from a pickup station in which clamping means on the carriage engages with the belt at a spaced location from its leading edge through an affixation point on the winding drum at which the leading edge is engaged so that it may be wound on the drum. The carriage carries the clamping means and in addition it carries first and second limitation members which are engageable with the metal sheet between the clamping location and the forward edge. The limitation members are mounted on the carriage so that they may be moved outwardly and inwardly in respect to the clamping means and upwardly and downwardly in respect to the associated sheet so that they may be selectively and independently positioned so as to locate the edge of the sheet exactly in respect to a fixation point on the windup drum.
