Abstract: The apparatus for winding a foil sheet, especially a plastic foil sheet, on a roll core is used in a step in the winding of a foil sheet into a foil sheet roll with a foil sheet winding machine. The apparatus comprises a contacting roll, a roll core receptacle and a cross cutter. A roll core put in the roll core receptacle is placed on the contacting roll and is drivable by it with the intervening foil sheet running to the downstream foil sheet roll. The foil sheet is cuttable with the help of the cross cutter between the roll core and the downstream foil sheet roll. Further the leading end piece of the next following foil sheet formed by cutting is receivable by the roll core. Above the roll core received in the roll core receptacle a foil sheet press device is mounted which is placeable on the roll core by a pivot motion and has a press element travelling with it during pivoting. The press element, advantageously a press belt, embraces the roll core on the side of the roll core facing away from contacting roll and forms an engaging wedge space with the roll core. An air blower tube is located between the engaging wedge space and the cross cutter under the next uncut foil sheet. The blower air streams from this blower tube are directed in the engaging wedge space and/or substantially parallel to the engaging direction of the engaging wedge space to assist in engaging the next following foil sheet on the roll core.

Abstract translation: 在箔片卷绕机将箔片卷绕成箔片卷的步骤中，使用卷绕箔片，特别是塑料箔片的卷绕机的卷绕装置。 该设备包括接触辊，辊芯容器和交叉切割器。 将放置在卷芯容器中的卷芯放置在接触辊上，并且可以通过其中间的箔片运行到下游箔片卷来驱动。 借助于卷芯和下游箔片卷之间的交叉切割器，箔片是可切割的。 此外，通过切割形成的下一个下一个箔片的前端片可以由卷芯接收。 容纳在卷芯容器中的辊芯上方安装有箔片压制装置，其可通过枢转运动放置在辊芯上，并且在枢转期间具有与其一起移动的压力元件。 压榨元件，有利地是压榨带，包围辊芯侧面上的辊芯，其背离接触辊并与辊芯形成啮合楔形空间。 鼓风管位于接合楔形空间与下一未切割箔片下的十字切割器之间。 来自该鼓风机管的鼓风机气流被引导到接合楔形空间中和/或基本上平行于接合楔形空间的接合方向，以帮助将下一个随后的箔片接合在卷芯上。
