Abstract: An improved device for the uniaxial or biaxial stretching of plastics material portions. The device includes a stretching frame with two pairs of mutually perpendicular guide rails with clips for stretching a plastics material portion, which clips are movable away from or towards each other. The device is constructed such that in addition to the starting position at the beginning of a stretching process and the end position after performing a stretching process, the guide rails and thus the clips seated thereon are additionally movable into a loading position. The loading position is arranged so that it lies asymmetrically within the stretching frame and is thus closer to at least one longitudinal side of the stretching frame than to the opposite side of the stretching frame.
