A device for connecting the rear end of a web of material, which downstream undergoes a treatment or processing operation, to the front end of a following web of material, comprises a frame (11) with guide rollers which determine a throughput section for the web of material, two pressure elements (12, 13) which are fitted on either side of the throughput section, and which are movable towards each other and away from each other virtually at right angles to said throughput section, and also cutting elements (30) for cutting through the one and/or the other web of material. The pressure elements each comprise a bar which is fixed between two plates (15, 16) movably suspended in the frame, each bar having a pressure face extending virtually along its entire length in the direction of the throughput section. The bars are provided with a slit-type space extending in the lengthwise direction of the bar. The slits connect to each other when the bars are lying against each other. Between the two bars at the level of these slits the wire-type cutting element (30) is fitted which can be displaced from a central position into the one or the other recess for cutting through a web of material. |
