摘要:
A device for forming a peripheral edge of a cup blank made of paper material, having at least one forming tool, wherein the forming tool is arranged on a tool carrier which is arranged so as to be rotatable about a rotation axis, wherein the rotation axis coincides with a longitudinal centre axis of the cup blank inserted into the device. The forming tool and the tool carrier are configured and arranged so as to travel along a profile, deviating from a circular shape, of the peripheral edge of the cup blank.

A double-walled cup and a process for production of the cup are described. The cup includes an inner cup and a tube-shaped outer sleeve, which is formed from a blank of paper material joined at its ends. The tube-shaped outer sleeve is slid axially onto a prefabricated inner sleeve and secured. The tube-shaped outer sleeve is formed from a flat blank by joining the ends of the blank before being slid on, whereby the ends of the blank are joined by an adhesive applied to a limited area of the outer sleeve. The ends of the blank are joined by a thermoplastic material in the form of an adhesive, which for example can be a hot-melt adhesive or a sealing varnish.

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.

A cup made of paper material having a fillable interior is provided. The cup is formed by a conical sleeve and a bottom. The bottom is attached to the sleeve at the lower end of the interior with a bottom skirt in an essentially liquid-tight way. The sleeve and/or the bottom in the area of the bottom skirt and/or the bottom skirt itself includes, at least in one area along the periphery, an outwardly projecting widening. A lower edge of the widening forms a standing surface for the cup. The widening can form a structure for holding another cup of the same type, which structure can act together with a similar cup during stacking. The cup can include a heat-insulting outer sleeve.

An arrangement is described for transporting cardboard blanks or the like in the flat, in particular for book cover or letter file machines. The arrangement includes at least two sequenced transport belts extending parallel to one another, which are guided over deflecting wheels. Grippers are applied to the transport belts to hold the blanks. The grippers comprise controlled, swivelling clamping elements, which can be opened at the deflecting wheels.

Method for manufacturing a cup from a conical sleeve and a pot-shaped base. The base has a base face and a circumferential wall starting from the base face and inserted from a large opening in the conical sleeve into the sleeve in the direction of a small opening in the sleeve. The method includes: partially covering a radially outer circumferential face of the wall of the pot-shaped base with an annular covering sleeve, positioning the covering sleeve together with the base in the direction of the small opening in the sleeve until the predefined relative position between the sleeve and the base is reached, pulling out the covering sleeve between an inner side of the sleeve and the radially outer circumferential face of the base, the base remaining in the predefined relative position, and connecting the radially outer circumferential face of the base and the inner side of the sleeve in an essentially fluid-tight manner.

Method and apparatus for producing a twin-wall cup from paper or paper-like material including placing an inner cup with a sleeve and a base onto a mandrel, laying a flat segment onto an outer side of the inner cup, opposite to the mandrel, shaping the flat segment to form an outer jacket, which surrounds the inner cup, and fixing the outer jacket on the inner cup by means of a material engagement connection of outer jacket and inner cup, in particular by means of adhesive bonding, wherein at least one spacer is attached to an inner side of the flat segment and/or to an outer side of the sleeve of the inner cup before the flat segment is laid on the inner cup.
