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: In the case of a heat setting chamber for the continuous heat setting of yarns, entry and exit openings are provided, through which transport belts are fed and onto which transport belts the yarns are placed in loops. In the area of the entry and exit openings, ventilation seals are provided, on which the heat setting medium flows against the loops from underneath. The mouths of extractor vents are arranged vertically over the ventilation seals. The heat setting medium can thus penetrate the yarn loops in the area of the entry and exit openings simultaneously from above and below.

Abstract: A device for transporting yarn comprises a central mast which is equipped with a plurality of circulating transport belts which are arranged when viewed in cross section in polygonal form. At least one yarn is wound around the transport belts and the central mast in controlled loops by means of a winding flyer, whereby the central mast is supported in a mounting on its end towards the winding flyer. In the area of its other end, the central mast is provided with supported rollers, which are supported by a supporting roller arranged outside the loops. The supporting roller and the transport belts are each provided with their own drives. The speeds of the transport belts, the supported rollers and the supporting roller can thus be synchronized exactly with each other.

Abstract: Carpet yarns which have been previously mechanically compressed, are heat set in a yarn heat treating chamber by superheated steam. The yarn treating chamber operates under atmospheric pressure. Several yarns are passed through the yarn treating chamber on respective perforated conveyor belts. The steam is conducted so that it is forced to flow downwardly through the yarns and through the permeable conveyor belts. To avoid the formation of condensate water on the conveyor belts, the belts are in the form of nonmetallic nets, upon which the yarns are deposited in the form of loops.

Abstract: Empty cans are formed in preparation for being filled. The empty can includes a sleeve and two end walls. One of the end walls contains a filler opening for enabling product to be subsequently inserted into the can and thereafter discharged from the can. The filler openings can be closed by tear strips or screw caps.

Abstract: A device for gripping and decollating a bottom blank comprises a rotary shaft with a flat outer peripheral portion. Suction orifices in the shaft extend through the flat surface portion and communicate with suction cups carried by the shaft. Free outer edges of the suction cups contact the bottom blank, whereupon the application of suction causes the suction cups to contract. The suction orifices include enlarged outer portions for receiving the contracted suction cups such that the bottom blank is pulled flush against the flat surface portion of the shaft for a more effective application of suction forces.

Abstract: A book covering machine includes a mechanism for gripping and decollating the lower blank of a stack of blanks whose front portion is slightly bent relative to a rear portion thereof. The mechanism includes a support surface for the stack, the inclination of which surface can be adjusted relative to a front stop, whereby the angle between the support surface and the front stop can be made to correspond to the angle between rear and front portions of the stack.

Abstract: A folded container comprises a rectangular bottom and four folded-out sides. A double walled border flange extends around the periphery of the container parallel to the bottom. The free open edges of the border flange face toward the external surfaces of the sides. The sides are connected by means of folded, triangular corner sections. Two border strips forming portions of the border flange are provided with narrow recesses which mate with correspondingly shaped projections disposed on the edges of some of the corner sections. The projections snap into the recesses upon the folding out of the sides to render the container self-supporting in the erected position for subsequent processing prior to the bonding of the individual surfaces.

Abstract: In the manufacture of a book cover, a cover sheet is glued to cardboard panels and portions of the sheet are folded around edges of the panels. The glued unit is then passed through a press comprising pairs of press rolls spaced apart in the direction of travel of the glued unit. One roll of each pair contains circumferentially spaced recesses along its outer periphery. The recesses prevent the application of pressing forces to the unit when the recesses reach the unit, whereby an interrupted pressing action is achieved. Each pair of rolls is operated to apply pressing forces to regions of the cover not pressed by the other pair of rolls.

Abstract: Textile material is transferred by an upstream conveyor to a downstream belt conveyor such that a front end of the material rests on the downstream conveyor and a rear end thereof rests on the upstream conveyor. The upstream conveyor is displaced relative to the downstream conveyor such that the upstream conveyor passes over the downstream conveyor in a manner causing the material to be folded about a transverse fold line and deposited onto the downstream conveyor. The downstream conveyor is actuated to transfer the folded textile material to a folding mechanism.

Abstract: An apparatus for the making of container jackets from flat cardboard or plastic blanks. The blank is folded around a core by means of pivoted fingers which are moved toward the core while ends of the fingers are guided in guide passages to produce pivoting of the fingers. The fingers pivot such that blank-engaging ends of the fingers fold the blank around the core. The slide guides are mounted for pivotable movement simultaneously with the movement of the fingers toward the core, whereby the movement of the fingers can be adapted to cores of different diameter by changing the distance of movement of the carrier, i.e., the same fingers and slide guides can be used with an infinite number of core diameters.

Abstract: An apparatus for producing container jackets from blanks comprises a winding core around which a blank is wound in a manner forming an overlapped area. A pressing element is arranged to engage and press the overlapped area. An actuating mechanism urges the pressing element against the overlapped area to apply a pattern of radial pressing forces along the length of the overlapped area. The actuating mechanism is able to longitudinally shift the pressing force pattern along the overlapped area to adapt the apparatus to the pressing of different types of jackets, such as jackets of different lengths.

Abstract: A folding tray is formed by a single foldable blank which includes a bottom wall, lateral walls, and corner sections. The lateral walls and corner elements include border sections which form a horizontal rim around the periphery of the tray. Each corner section includes a generally rectangular center part and a pair of transition sections on either side thereof. Each transition section comprises a pair of triangular parts joined to each other by a fold line and joined to the center part and associated lateral wall by fold lines. Between the center part and its associated border section is a lens-shaped equalizer section which avoids the creation of an abrupt angle between the center part and border section to enable the border section to lie flat in the erected tray. The equalizer section is defined by a pair of curved fold lines which converge to form points situated adjacent the respective transition sections.

Abstract: In the course of the preparation of a double-walled paper container, two jacket blanks are wound in circumferentially offset relationship with the end edges of each blank disposed in mutually facing relationship following the winding. The joints formed by the end edges are preferably covered by a foil in the form of a tube which is applied after the blanks have been wound.

Abstract: In the manufacture of paper containers, a paper jacket is wound upon a first support mandrel. The wound jacket is transferred to a second support mandrel by a transfer device. A positioning device in the form of a circular ring is situated in front of the second support mandrel. The jacket is pushed through the ring en route to the second mandrel and thus becomes aligned with said second mandrel while simultaneously being shaped in accordance with the circular cross-section of the ring to conform to the circular cross-section of the second mandrel.

Abstract: The open cut edge of a cardboard blank is covered by a cover strip folded around the cut edge. The cover strip is cut from a band having a width corresponding to the length of the cut edge to be covered. The strip is held flatly on a folding device and is subsequently folded around the cut edge of the cardboard blank. On the folding device a folding slit is provided which may be slid, together with the cover strip, over the cut edge of the cardboard blank in a direction transversely of such edge.

Abstract: A paper container has a bottom in which there is impressed a deformation groove to allow the bottom to deform in response to reduced internal pressures occurring as a hot liquid cools inside of the closed container. The bottom is formed in a continuous one-step process in which a series of coaxially arranged, telescoping tools travel relative to one another along a common axis to form the bottom with the deformation groove and a bent outer edge.

Abstract: In wound, preferably cylindrical paper containers, reinforcing rings of a synthetic plastic material are applied to the upper and possibly to the lower cut edges and joined by welding with the jacket. In order to insure that the core of the ring remains cold during welding and only the surface becomes liquid, thin-walled projections are provided in locations of the ring where welding is desired and are rendered flowable immediately prior to the placing of the ring on the jacket. Thus, the ring retains its structural integrity while being rendered weldable.
