Abstract: A feeding unit for an inserting system has a transport device and at least one stack support for a product stack from which products are individually and in sequence removed from an end face of the stack in a downward direction and transported father by the transport device. At least one support roller is positioned at the end face of the stack in an area above the transport device and adjustable in a direction transverse to the end face of the stack and in a direction of height of the end face of the stack.

Abstract: A collector for stacking sheets of paper, plastics, and cardboard has a feeding device and a tray downstream of the feeding device in the feeding direction. The tray is arranged in a lowered position relative to the feeding device. A stop is provided downstream of the tray. At least one transport roll transports sheets individually from the feeding device onto the tray to form a stack. An adjusting element is arranged in an area where the feeding device and the tray adjoin, wherein the adjusting element is adjustable between a lowered rest position and a position of use lifted relative to the rest position. In the position of use, the adjusting element lifts a trail end of a first sheet that has reached the tray such that a following second sheet is moved into a position underneath the trail end of the first sheet.

Abstract: Buckle folding machine including folding pockets, which have a paper stop each. One folding pocket being for collection and subsequent joint folding of a plurality of sheets. From the folding pocket the collected sheets of paper pass together through a folding mechanism, having a draw-in point formed by upper and lower draw-in rollers and having at least one pair of folding rollers forming a folding point. A sheet feeder with a conveyor track directed toward the draw-in point, in which a stacking ramp is located, is arranged in front of the draw-in point.

Abstract: A buckling-type paper sheet folder comprises a protective housing (7) and two pairs of folding cylinders (W1, W2, W3, W4) which are mounted in a cylinder frame (1) and conjointly driven by an electric motor (4). Folding pockets (5,6) and the cylinder frame are enclosed on all sides by the housing which has two parts, namely a base (8) and a cover (9), that are hinged and/or detachably connected to each other. In the base, a box-like compartment (12) is formed below the folding pockets accommodating the cylinder frame. The cover comprises a wall (45) extending between vertical side walls (40,41) and covering the upper foldin pocket (5) and having a portion (48) forming the upper boundary of a sheet intake opening. The cover further comprises a second wall (54) extending above the second folding pocket (6) inwardly, to form the lower boundary of the intake opening (51), and having a front portion 39.

Abstract: The present invention provides a device that makes possible to turn individual sheets of paper 3 by an angle of 90.degree. during their transport without a change in their direction of feed, arrow 8, even at high speeds of feed. In the device according to the present invention, a stopping roller 22 with a pressure ball 33, is driven opposite to the direction of feed, arrow 8 and is arranged directly in front of the taut side 23' of a conveyor belt 23 in the direction of feed, arrow 8. A longitudinal row of pressure balls 22-29 are in contact with the conveyor belt 23. A drive roller 34 is driven in the direction of feed, arrow 8, and is provided with a pressure ball 35 in contact with a higher contact pressure than the pressure ball 33 to the stopping 22. The driver roller 34 arranged laterally offset from the feed web center 38 and directly in front of the roller stopping roller 22.

Abstract: A sheet separator for a sheet feeder comprises a friction cylinder which is rotatable for feeding a sheet from a stack of sheets. A retaining member is mounted for radial movement with respect to the friction cylinder. The retaining member has a friction surface which holds back other sheets in the stack and which forms with the friction cylinder a passage gap which is adjusted to the thickness of a sheet to be fed. A carrier is connected to and supports the retaining member. An adjustment mechanism is provided between the carrier and the retaining member for adjusting the passage gap width. A bracket is mounted for radial movement on the carrier and has a contact surface for engaging the friction cylinder or a sheet held in the passage gap. Signal switch is provided in the bracket and is activated by a checking element which is movably mounted to the bracket and engaged with either the carrier or the retaining member.

Abstract: A buckling-type paper sheet folder comprises at least two pairs of folding cylinders W1 and W2 and two folding pockets F1, F2. The adjustable sheet stops 65,66, embodied by stop rails, of the folding pockets F1, F2 are secured to endless belts 67,68,69 and 70 which are drivable, conjointly two and two, through a manually actuable shaft 79 or 80. Scales of length S1 to S8 are carried on scale bands 48 and 49 which are associated each with one of the folding pockets F1 or F2 and displaceable by, the respective drive shafts 79, 80 in synchronism with the sheet stops 65, 66. The scale bands 48 and 49 are mounted in the housing to be visible through windows which are provided with reference marks. The sheet stops 65 and 66 can be set to the desired position through the closed housing by means of knobs 81 and 82. To facilitate the setting of the sheet stops, a plurality of scales S1 to S8 is provided on each scale band, each associated with a folding manner and sheet size, and made separately noticeable by a light.
