A sheet stacking apparatus includes a frame, a round member directly or indirectly connected to the frame, and an arm directly or indirectly connected to the frame. The arm is rotatable to rotate between a first position and a second position. The arm is positioned to bias sheets toward the round member when in the first position, and the arm is positioned to bias the sheets away from the round member when in the second position.

Apparatus is provided for manufacturing a wipe in a three dimensional form out of an essentially flat piece of material. The apparatus produces a blank (12) of essentially flat planar form with a pleat folded on each side. The folded blanks are fed by a conveyor belt (21) to an opening station (22). The opening station comprises a pair of movable pinch rollers (34, 35) which selectively grab individual blanks from the conveyor belt and feed them via belts (32, 33) to a pair of counter-rotating drums (30, 31). The blanks are ejected from the drums, which partially opens them up in the process. The partially open blanks are fed onto a shaped former (37), where the final process of forming the wipe into its chosen three dimensional form is completed.

A pair of conveyance rollers are arranged for signatures. The signatures is conveyed through the pair of conveyance rollers to a stacking unit while being sandwiched from both sides thereof between the pair of conveyance rollers. In response to passage of a signature for a sheet stack through the pair of the conveyance rollers, the conveyance rollers is switched from conveyance rotation to intermittent rotation to cause the pair of the conveyance rollers to keep the signatures for a next sheet stack from being conveyed to the stacking unit. In response to the stacking unit becoming ready to receive the signatures for the next sheet stack, the conveyance rollers is switched from the intermitted rotation or the stop to the continuous rotation to cause the pair of the conveyance rollers to convey to the signatures to the stacking unit.

Each of the sheets is conveyed by a horizontal conveyance unit in a state of being overlapped with a next sheet from above. Each of the sheets is conveyed out of the horizontal conveyance unit in a state of being folded along a fold line with the fold line oriented upward, the fold line extending in a conveyance direction of the horizontal conveyance unit. An oblique conveyance unit receives the sheet from the horizontal conveyance unit and successively conveys the sheets in an oblique downward direction. A sensor is arranged to detect passage of the sheets at a position where steps pass. Each of the steps is formed by two sheets adjacent to each other diverted to the oblique downward direction by the oblique conveyance unit.

A method and an apparatus for forming advertising media compilations respectively consisting of one envelope and a plurality of inserts. Each advertising medium suitable for use as an envelope for an advertising media compilation to be formed is recorded in a computer-aided machine control. For each recorded advertising medium, an offset value is defined which corresponds to the required projecting length, relative to the associated inserts, wherein this offset value is used for forming the required projecting length in case of a changeover from one advertising media compilation to another advertising media compilation having an envelope that differs from the first envelope. The apparatus is respectively provided for this with a separate drive unit, connected to the computer-aided machine control, for at least one of the separating out and feeding elements and to the conveying element.

The present invention relates to an apparatus and a method for folding and winding a predetermined length of non-woven fabric used for the industrial production of moistened wipes. The apparatus for folding and winding a predetermined length of non-woven fabric from a roll wound on a core is mounted on a countertop, equipped with a housing, provided with a drive unit. Mounted on a hub (1) is a cylinder (2), to which eccentrically attached are rods (3) from which at a certain distance is mounted a linear feed (4). The hub assembly (1) with the cylinder (2) with the rods (3) and the linear feed (4) can be mounted vertically or horizontally.
