Abstract

The invention relates to an output unit for a provision individually per track of sheet material for placing beneath products fed on two or multiple tracks, in particular beneath food portions, said output unit comprising a draw-in device that is configured to draw in individually per track a respective one material web of the sheet material per track and that in particular has at least one driven draw-in shaft and at least one draw-in pressure unit; a separation device that is configured to separate the sheet material from the material webs; and an ejection device that is configured to discharge sheet material on two or multiple tracks and that comprises a driven ejection roller and an ejection counter-unit that forms an ejection gap for the sheet material together with the ejection roller, wherein the ejection roller is jointly associated with at least two tracks.

First claim

The invention claimed is:

1. An output unit for a provision individually per track of sheet material for placing beneath products fed on two or multiple tracks,
said output unit comprising a draw-in device that is configured to draw in individually per track a respective one material web of the sheet material per track;
a separation device that is configured to separate the sheet material from the material webs; and
an ejection device that is configured to discharge sheet material on two or multiple tracks and that comprises a driven ejection roller and an ejection counter-unit that forms an ejection gap for the sheet material together with the ejection roller,
wherein the ejection roller is jointly associated with at least two tracks.

2. The output unit in accordance with claim 1 , wherein the ejection gap and a draw-in gap, which is formed by the at least one draw-in shaft and the at least one draw-in pressure unit, are disposed in a plane that is arranged at least substantially perpendicular in a position of use of the output unit.

3. The output unit in accordance with claim 1 , wherein the draw-in device has at least two draw-in shafts, wherein one draw-in shaft is associated with a respective one material web, and/or wherein the draw-in device has at least two draw-in pressure units, wherein one draw-in pressure unit is associated with a respective one material web.

4. The output unit in accordance with claim 1 , wherein the separation device comprises at least one blade unit.

5. The output unit in accordance with claim 4 , wherein the separation device is configured to separate sheet material individually per track, wherein the separation device has at least two individually driven blade units, wherein one blade unit is associated with a respective one material web.

6. The output unit in accordance with claim 3 , wherein the at least two draw-in shafts are coaxially arranged, and/or wherein shafts of pressure rollers of the at least two draw-in pressure units are coaxially arranged, and/or wherein blade shafts of the at least two blade units are coaxially arranged.

7. The output unit in accordance with claim 5 , wherein the at least two draw-in shafts are coaxially arranged, and/or wherein shafts of pressure rollers of the at least two draw-in pressure units are coaxially arranged, and/or wherein blade shafts of the at least two blade units are coaxially arranged.

8. The output unit in accordance with claim 1 , wherein the output unit is designed in a modular manner as an output module, and/or wherein the draw-in device, the separation device, and/or the ejection device is/are in each case designed in a modular manner as a draw-in module, a separation module, and/or an ejection module.

9. The output unit in accordance with claim 1 , wherein the output unit, the draw-in device, the separation device, and/or the ejection device in each case comprises/comprise at least one drive unit that is configured to drive the corresponding unit.

10. The output unit in accordance with claim 1 , wherein the ejection device has a mechanical interface by means of which the ejection roller can be drive-effectively coupled to an external drive unit.
