Abstract: Cup made of paper material having a fillable interior space formed by a shell and a base. The base via a skirt at the lower end of the interior space is fastened in a substantially liquid-tight manner to the shell, and a lower periphery of the skirt forms a footprint for the cup. The cup has an external shell composed of a planar blank of paper or paper-like material. Longitudinal edges of the blank are connected to one another in an overlap region so that the external shell forms a sleeve. The external shell has a frustoconical shape having a first cone angle and, except for the overlap region, from the predefined spacing to the lower end is configured in a single ply. The shell, from the predefined spacing to the lower end, at least in portions tapers more heavily than in the region above the predefined spacing.

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.

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: An arrangement for manufacturing a paper can includes processing stations arranged one behind the other along two star-shaped wheels. Packaging material from supply stores is fed to each star-shaped wheel. The two star-shaped wheels and the processing stations arranged thereto are disposed on the same machine frame. The packaging material for both star-shaped wheels are fed from a joint material supply station. Thereby, a compact construction and reduced operational procedure are achieved.

Abstract: 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.

Abstract: An arrangement for transporting yarn through a heat setting chamber has a rotatably driven central mast which is equipped with transport belts arranged around the mast in the form of a polygon in cross section. At least one yarn is wound around the transport belts in loops by means of a winding flyer. At the latest when arriving at the heat setting chamber, the loops should have a larger circumference than the polygon formed by the transport belts for the purpose of forming a shrinkage reserve. This is achieved in that auxiliary belts, ending upstream of the heat setting chamber, are arranged in the area of the winding flyer, the speed of which auxiliary belts corresponds to the speed of the transport belts and which enlarge the polygon to the amount of the desired shrinkage reserve.

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.

Abstract: A heat-insulating cup comprises an inner sleeve and an outer sleeve. The latter is supported against an upper and a lower area of the inner sleeve. An annular space is located between the inner sleeve and the outer sleeve, which annular space is free of any additional elements. A joint bottom is arranged to the inner sleeve and the outer sleeve. In the upper area, the inner sleeve has a sudden widening, on top of which the outer sleeve is disposed.

Abstract: A dish-shaped container is made from a folded cardboard blank sealable on both sides. The container has a rectangular bottom and four upfolded lateral panels which are connected to the container corners respectively by four triangular-shaped corner panels. A circumferential double-walled outer flange parallel to the bottom consists of first and second outer strips. The first outer strips are folded on the respective lateral panel, and the second outer strips are aligned with their cut edges towards the outer surface of the respective lateral panels. The first outer strips extend continuously over the entire periphery of the container, so that there are no breaks up to the filler area. The second outer strips are left out in the area of the corner panels. As a result of the double layer, the container comprises a reinforced outer flange and is in addition absolutely impermeable to liquids in the corner areas.

Abstract: A machine for producing containers comprises processing stations with components adaptable to the shape and size of the material sections used for the container. In the case of a change in form, in particular a change in the format of the sections of material to be used, it is necessary to change the relevant adaptable components. Instead of the conventional approach where the new components must be fine-tuned after an exchange has taken place, fitting surfaces are provided at the processing stations, against which a section of the adaptable components can always be placed in the same position. Therefore, time-consuming installation of exchangeable machine components is avoided.

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: 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.
