  • Patent number: 7670274
    Abstract: A folding station of a folding box gluing machine for processing a blank having a middle piece and side pieces which are attached to sides of the middle piece and which are deflected upward and inward along folding grooves between the middle piece and the side piece across a folding line toward the lengthwise middle of the blank and then folded up in order to produce a folding boxes, includes a folding strap that deflects the side pieces and folds them upward. The folding strap is guided by a folding shunt, a positioning roller, and one or more deflection and pressure rollers. A distance between the folding strap from the folding line of the blank is adjustable, such that the folding strap acts on an outer region of the side piece.

  • Publication number: 20090227437
    Abstract: A receiving apparatus of a folding box gluing machine for receiving guide elements, in particular a roller rail, and/or tools, such as folding devices. The guide elements and/or tools can be moved from an active position above the folding box transport plane into a parked position. The receiving apparatus has a frame, to which the guide elements and/or tools are fastened, and this frame can be pivoted about a pivot axis, the pivot axis being oriented parallel to the folding box transport direction. The receiving apparatus has a stop device which fixes the position of the frame in its parked position, with the result that said frame can be reached ergonomically by the machine operator. The frame can be moved from a horizontal position, in which the guide elements and/or tools are situated in their active position, by a pivoting movement about the pivot axis by less than 90° into an oblique position, in which the guide elements and/or the tools are situated in their parked position.

  • Patent number: 7497067
    Abstract: A device for packing flat articles in transport containers includes a feeder for feeding the flat articles in imbricated form and a conveyor disposed downstream of the feeder, in travel direction of the flat articles. The conveyor has an at least approximately vertically extending end for discharging the articles into the transport containers for filling the transport containers therewith at a filling location. Equipment for further conveying the transport containers at the filling location includes two lateral belt conveyors disposed at the filling location for moving the transport containers forward during the filling thereof with the articles.

  • Patent number: 7402129
    Abstract: A machine for folding and gluing folding boxes has a first folding station and at least one second folding station that follows downstream. Machine components are provided which can be positioned transversely and which contain conveying elements for blanks for the folding boxes and at least one adhesive application unit. The machine further has actuating drives for positioning the machine components, and a rotary station which is disposed downstream of the first folding station and upstream of the second folding station. The rotary station has a fixedly disposed transport device for the blanks. A controller controls the actuating drives of the machine components which are provided in front of and behind the rotary station and which can be positioned transversely, as a function of the type of folding boxes that is to be produced.

  • Patent number: 7338422
    Abstract: A folding box gluing machine contains one upper and lower transport belt disposed on each side of the machine. A lower transport belt is guided in a roller cheek and an upper transport belt is guided in a roller rail. A central roller cheek and a central roller rail, which can be fed in, are further disposed in the center of the machine and in each case guide a central transport belt. A device for inserting side parts of a folding box blank, which side parts overlap and/or engage in one another, is provided. The device is fastened to the central roller rail and is driven by the central upper transport belt through a V-shaped belt. The device for inserting is held on a holding frame in a load bearing frame which can be fed in separately. The central roller rail is additionally fastened to the holding frame.

  • Patent number: 6973766
    Abstract: A device for packing flat articles in transport containers, particularly folded-flat folding boxes in casing cartons, includes a feeder for feeding the flat articles in imbricated form. A conveyor is disposed downstream of the feeder and has an end for discharging the articles into the transport containers at a filling location. Equipment is provided for further conveying the transport containers at the filling location. A transition is provided between the feeder for the flat articles and the downstream conveyor. The transition is an accumulating and transfer device and has an imbricating roller adjustably secured on the conveyor and a height-adjustable hold-down bar fastened to the conveyor. The hold-down bar and the imbricating roller are adjustable in position for coupling with one another.
