Abstract:
A wound double-walled container and method of manufacturing the same from coated paper includes two blanks which are placed one above the other and which form the container walls. The blanks are arranged mutually offset in such a manner that narrow foldable strips project laterally and foladble rim portions extend at the top and bottom, which are folded over for sealing the inwardly and outwardly and endwise disposed cut edges. The folding-over takes place either after the winding of the blanks or while the individual blanks are still flat, which thereafter are wound separately one after the other about a winding mandrel and are sealed.
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 arrangement for covering a flat lying blank, preferably made of paperboard, with a cover, as is in particular applicable in the manufacture of book cases. The arrangement comprises fixing means for simple coupling of a circular cutting device. This circular cutting device comprises transport means for direct feeding of the cut blank to the arrangement.
Abstract:
A process and an arrangement for covering a flat-lying blank, preferably made of cardboard with a cover, in particular applicable in the production of book covers is described. The covering takes place in cycles in a number of working stations, whereby an overall cycle time can be given to each working station in advance. Each working station comprises at least one working means, to which at least one sub-cycle time is assigned. It is provided that in the case of a constant remaining overall cycle time, at least one sub-cycle time assigned to the working means of a procedural step is adapted to the processed materials. The present invention is in particular applicable when at least one edge of a cover applied to a blank is folded over. The folding over of the edge takes place thereby in a folding station within the pre-set overall cycle time. Within one cycle, at least the following procedural steps are carried out: “transport”, in which the blank with the cover is transported into the folding station, “preparing”, in which at least one folding means is placed to the edge of the cover, and “folding and pressing”, in which the folding means folds over the edge of the cover and presses it onto the blank. It can in particular be provided that the ratio of the sub-cycle time “folding and pressing”, assigned to the folding means to the overall cycle time is variable.
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 heat insulating container has an inner container body and a sleeve. The sleeve is attached to the circumferential wall of the inner container body by attaching surfaces, and has cut edges extending transversely to the circumferential direction. The attaching surfaces are only arranged extending transversely to the circumferential direction. A simplified application of the sleeve to the circumferential wall of the inner container is thereby made possible and less material and working time are required for production.

Abstract:
An arrangement for rolling the frontal end of a deformable sleeve-shaped container jacket comprises a supporting surface which radially supports the container jacket in the area of its end. A ring-shaped cavity is arranged radially adjacent thereto, which cavity is closed at the bottom and open at the top. The cavity has an essentially semicircular cross-section. The cavity is provided in circumferential direction with a plurality of pocket-shaped recesses in the transitional area between the supporting surface and the bottom, between which recesses rolling ridges, as part of the original cavity surface, remain. The purpose of this design is to effect a reduction in the deformation forces when the frontal end of the container jacket is being rolled.
Abstract:
A container comprises a sleeve and two end walls. The sleeve is made of a tube having a plurality of paper layers. The end walls are inserted into the sleeve and are bonded in a sealed way thereto. According to the present invention, each of the end walls has a rim which projects outwards, around which rim the tube is bent and bonded by means of heat sealing. A stable, sealed bonding is thus obtained, whereby the application of different materials for the end walls is possible.
