The apparatus is noteworthy in that the driving drum 3 incorporating the cutting member is mounted transversely with free rotation between front and rear walls 1a-1b of the casing 1 and the roll of material for use is simply placed onto the drum, thereby also bearing in a rolling manner on a cylinder 16 which can rotate with respect to the said walls; the free strip to be drawn out extending under the apparatus after having been wound onto the drum and having been passed between two idler rolls 14-15 and an opening 1e of the casing; a device 18 which is sensitive to the weight of the almost-empty roll of material, pivots when the said roll is able to pass between the drum and the rotary cylinder in order to be received in a magazine 30 and actuates the automatic installation of a new roll retained up to that moment in the upper part of the apparatus; a profiled member traverses the drum in order to interact alternately with one or other of the front or rear walls of the casing so as to stop the drum after the cutting operation and to place the drum back in the standby position. <IMAGE> |
