Embodiment Construction

[0029] figure 1 The view of shows a folding mandrel 10 according to the invention, which has the shape of a truncated cone and around which a paper sector can be wound, as in image 3 as shown in Unwind Status. In this case, the paper segments are dimensioned in such a way that after winding there is an overlap, so that the paper segments can be bonded in the area of ​​the overlap in order to thereby obtain a frustoconical sleeve. These frusto-conical sleeves can then be provided with a bottom for serving as an inner cup for the beverage. These frusto-conical sleeves can also be inserted over the inner cup to form an insulating shell if a double-walled cup for hot beverages is to be manufactured.

[0030] The folding mandrel 10 is provided with a groove 12 which has a rectangular cross section and extends from the conical outer surface of the folding mandrel 10 inwards in the direction of the center axis 14 of the folding mandrel 10 . The groove 12 extends parallel to the c...

Abstract

Folding mandrel, device and method for manufacturing glued sleeves. The invention relates to a folding mandrel for a device for manufacturing glued sleeves, in particular paper sleeves for the manufacture of paper cups, where the folding mandrel is provided for winding of a plane segment and is so dimensioned that in the wound-on state of the segment an overlap containing adhesive is obtained. In accordance with the invention, the folding mandrel is provided with at least one recess for receiving any adhesive escaping from the overlap. Use for example for the manufacture of paper cups.

Description

technical field [0001] The invention relates to a folding mandrel for a device for processing adhesive sleeves, in particular for processing paper cups of paper cups, wherein the folding mandrel is used for winding flat segments and is dimensioned such that at the end of the segment The coiled state produces a lap joint containing adhesive. The invention also relates to a device and a method for processing adhesive sleeves. Background technique [0002] Known folding mandrels for the production of adhesive sleeves for the production of paper cups have a conical shape on which a flat paper segment is wound. Adhesive is applied in the area where the overlap is to be produced before the paper segment is wound. After being wound onto the folding mandrel, the segments are pressed together in the overlapping region and the segments are connected to form a conical sleeve. In order to save paper, the overlap should be selected to be as small as possible and therefore cannot be co...
