Abstract: 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.

Abstract: A machine uses a method for producing a cup from an outer shell and inner cup. For this purpose, the machine includes first holding devices that are arranged on a first rotatably housed star- or wheel-like holding device carrier, and second holding devices arranged on a second rotatably housed star- or wheel-like holding device carrier. Further, a first working station arranged at least in the region of the first holding devices for carrying out first working steps and at least one second working station arranged in the region of the second holding devices for carrying out second working steps are provided. Finally, the machine includes a transfer station for transferring a finished outer shell from a first holding device to a second holding device.

Abstract: 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.

Abstract: An apparatus for manufacturing a sleeve for a paper cup and/or a paper cup comprises a machine frame and at least two star wheels, which are rotatably connected with the machine frame and which can be rotated in synchronized cycles. A first star wheel comprises a number of conical mandrels, on each of which one sleeve made of a flat-lying blank can be formed. The star wheels are positioned in one plane and are arranged to a vertical wall of the machine frame with horizontal rotary axes. The star wheels can be connected to at least one drive, whereby the drive is arranged on the side of the machine frame wall facing away from the star wheels.

Abstract: An outer sleeve for a double-walled cup and a process for manufacturing the outer sleeve are described, in which a flat-lying blank made from a paper material is joined in a tube shape by means of the overlapping of two longitudinal edges of the blank, and in which the outer sleeve in this form is provided with an inwardly rolled curled part. The curled-in part is glued or sealed onto the inside of outer sleeve in the area of the overlap.

Abstract: The invention relates to a device and a process for manufacturing sleeves, in particular paper sleeves for the production of paper cups, comprising a take-up mandrel for taking up a sleeve, whereby the take-up mandrel comprises a circumferential recess, also comprising a press roller for placing on an outer side of the sleeve and for forming at least one circumferential projection in the recess of the take-up mandrel. In accordance with the present invention, the recess is designed in the form of a shoulder. Application for example for the production of stackable double-walled paper cups.

Abstract: A device for the application of adhesive and machine and method for manufacturing paper cups. The device applies adhesive, particularly for the manufacture of a paper cup from at least one paper segment, and includes a stamp for the application of the adhesive. The stamp is made of a compression-resistant porous sintered material.

Abstract: A cup made of a paper material having a fillable interior, which cup is formed by a conical sleeve and a bottom.

Abstract: The invention relates to a method for fabricating a funnel, a tool for carrying out said method, and a funnel of flat material, more particularly of plastic-coated paper. The invention further relates to a receptacle for a pulverulent and/or liquid medium, comprising a funnel disposed in a pouring or discharging region. According to the invention, a blank of flat material is shaped to a funnel-shaped sleeve (3) having an outlet opening (30), an inlet opening (31), and an opening angle (?) and the funnel-shaped sleeve (3) is swaged in at least one subregion to effect enlargement of the opening angle (?).

Abstract: A process for producing a cup made of a paper material and comprising a fillable interior is described. A sleeve forming the interior is attached in an essentially liquid-tight manner to a wall of a pot-shaped bottom by means of the forming of a bottom skirt. In joining the sleeve to the bottom, two height areas of the wall of the pot-shaped bottom are provided. The wall of the pot-shaped bottom is joined only to a first height area of the sleeve, which is referred to as the fixed area of the bottom skirt. A second height area remains, in which the wall of the pot-shaped bottom is not attached to the sleeve, and which is referred to as the non-attached area of the bottom skirt. The bottom skirt can be widened subsequently in the non-attached area in at least one area along the periphery.
