1. In a feeding system for strip material for transporting a strip over a conveying distance of limited length, the improvement comprising the feeding system including a transfer carriage and a rail guide for guiding the transfer carriage, the transfer carriage defining a chamber for receiving the strip, the transfer carriage having means for fastening the strip during feeding of the strip over the conveying distance by temporarily holding the beginning of the strip, the transfer carriage having at both sides thereof a reversible linear motor, each for driving the transfer carriage over the conveying distance, the means for temporarily holding the strip beginning including at least one row of rotary wedges, the rotary wedges being freely rotatably suspended on pivot axes above the chamber of the transfer carriage, each rotary wedge having a curved outer clamping surface which extends eccentrically relative to the pivot axis so that regardless of the thickness of the strip, each rotary wedge frictionally engages the surface of the strip beginning before the rotary wedge reaches a stable, suspended position, first means located at the start of the conveying distance for engaging and rotating the rotary wedge into a clamping position in which it clamps the strip beginning resting on a lower wall of the chamber of the transfer carriage against the lower wall when the transfer carriage is started in a conveying direction, and second means located at the end of the conveying distance for engaging and rotating the rotary wedge into a release position in which it becomes disengaged from the strip beginning.
