Abstract: A sheet processing apparatus which is capable of stabilizing a stop position of the sheet bundle, to thereby enable creation of a high finish quality product, and is compact in size and can be manufactured at low costs. Conveyance belts convey the sheet bundle to a flattening position. A pressing roller flattens the folded spine of the sheet bundle by pressing the folded spine. Clampers hold the sheet bundle such that the sheet bundle is not moved when flattening is performed. A CPU starts to stop driving of the conveyance belts when the sheet bundle is conveyed to a predetermined location upstream of the flattening position in the conveying direction of the sheet bundle, and stops the sheet bundle at the flattening position by holding the sheet bundle with the clampers before the conveyance of the sheet bundle is stopped.

Abstract: Signatures (1) are individually gripped from a stack (2) by a rotatable extracting cylinder (A) and transferred to a first rotating opening cylinder (B) and a second rotating opening cylinder (C) which open the gripped signatures (1) at the edges (4, 5) opposite from the fold (3) and drop the signatures onto the transport device (6). To open and transport the signatures (1) onward, the signatures (1) are gripped at their respective protruding edge (5) by a clamping device (48) disposed on the first opening cylinder (B). Projections are provided which catch behind the above-referenced edges (4, 5) in the extracting cylinder (A) and transfer the edges to the clamping device (48). These projections include a guide arm (7) which is movably supported on the first opening cylinder (B) and moves in response to a rotation of the first opening cylinder (B) from a retracted position into a position projecting over the circumference (27) of the first opening cylinder (B).

Abstract: The disclosure relates to a method in the forming of packaging containers (1) which have sealing fins in which the packaging material is sealed inside-to-inside, and also projecting, double-walled corner flaps (8). In order to form a parallelepipedic packaging container, the corner flaps are folded down and sealed to the outside of the packaging container, which subjects a sealing fin running between the corner flaps to stresses which may entail untightness in the packaging container. This is avoided in that the sealing fin, prior to the downward folding operation, is deformed in that at least a portion of the fin (4) is laterally displaced in relation to adjacent portions of the fin.

Abstract: First and second drive rollers and a slideway feed in an envelope to be opened. A third drive roller drives the body of the envelope in a direction parallel to the fold connecting the flap to the body of the envelope, the drive roller rolling over the face opposite from the face against which the flap of the envelopes folded down, without rolling over the region close to the fold. A counter roller situated facing the drive roller, rolls over the face against which the flap is folded down, without rolling over the flap. An idler wheel situated facing the drive roller has a rim which rolls over the flap close to the fold connecting the flap to the body of the envelope, and which penetrates into the cylindrical volume defined by the straight generator lines of the third drive roller, so as to arch the body about an axis approximately parallel to the fold. A freely rotatable cone moves the flap and the body apart by being inserted into the space created by the arching.

Abstract: In the production of packs made of (thin) cardboard such as cigarette packs, complex folding processes may cause problems when blank portions are moved to the proper pack position, especially when blank portions are "too long" for the folding process. To remove this problem, the respective blank portion is, during the folding process, temporarily deformed in a way which shortens its effective length, i.e. curved in an arched manner. In the production of hinge lid packs having a collar (11) attached to a front wall (12) thereof in a single piece, this blank portion is, while being folded from an upright to a horizontal position, temporarily curved by a folding lever (58) applying pressure until the blank portion reaches the horizontal folding position.

Abstract: A device for the releasing of tabs found on the diagonally facing corners of tab-locked corrugated cardboard boxes. The boxes are moved along a track whereupon they are deformed to enable a release means positioned along the track to slip between major flap and the sidewall of the corrugated box to release a first tab. The box is then turned at least 90.degree. and the process repeated.

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.

Drive rolls are located rearwardly of the gate and are selectively drivable for dispensing wrap material onto the rear end of a guide pan extending beneath and engaged with a portion of bale-forming belts extending between lower rear and lower front belt support rolls carried by the discharge gate. A guide finger assembly is secured to the front of the pan and includes a plurality of fingers located in gaps between the bale-forming belts and including forward end portions curved arcuately about the lower front belt support roll for directing wrap material about the roll and into a pinch point defined between the belts and a bale desired to be wrapped by the material.

Abstract: In automatic preparation of flexible, disposable packing containers for materials such as eggs or fruits during intermittent transportation along a straight path of travel of each packing container, an opener cord is wound up and tied about the joint between receptacle and cover of the packing container while provisionally deforming, making use of the flexibility, the packing container so that the joint should assume an arcuate construction, and removal of deformation brings about tight winding-up of the joint so that pulling of the cord in a sealed packing container by users should enable easy opening of the packing container through breakage of the joint.

Abstract: Paper sheets are advanced seriatim between high speed upper and lower conveyor belts across a gap onto a slower speed multi-belt conveyor with which the upper high speed belts cooperate to form a sheet controlling tunnel. Static eliminating and sheet knock-down air is directed through the upper high speed belts and into the sheets traversing the gap. Advance of the sheets across the gap is facilitated by impermanent wave-like longitudinal stiffening rib deflection of the sheets where they leave the high speed conveyor belts. After each sheet has been fully received on the slow speed conveyor, its high speed travel is stopped by stop roll means to assure overlap of a succeeding sheet thereon. The stop roll means cooperate with the slower speed conveyor belts to effect impermanent wave-like longitudinal jam preventing stiffening rib deflection of the sheets.

Abstract: Bags are dispensed from a stack of bags by locating the stack of bags on a dispensing surface and elastically pinching the stack of bags to the dispensing surface with an elastic compression means. The bags are thus capable of being removed from the stack one at a time without otherwise disrupting the stack.
