摘要： An setup folding machine with at least two folding stations (F1, F2), which are formed by a pair of folding rollers (W1/W2; W2/W3) each. An intake device is provided including two feed rollers (T1, T2), which determines the speed of feed of the material to be folded, the intake device is located in a feed web (4) moving past the first folding station (F1). A enclosure feed mechanism is positioned directed toward the first folding station (F1), arranged behind the intake device. In order for an enclosure to be able to be optionally inserted into the first or second fold, the first folding station (F1) is associated with a knife-like deflecting member (6), which can be moved to the first folding station (F1) while the material is being deflected at the same time to form a fold, and can be actuated individually for each folding process by an electronic control device (21). An electromagnetcontrollable sheet deflector acting as a second deflecting member (26) is arranged directly in front of the folding pocket (25) located between the first folding station and the second folding station (F2), and the second deflecting member (26) can be moved from its resting position to the second folding station (F2) after the material to be folded has entered the folding pocket (25), while the material to be folded (43, 55) is deflected at the same time to form a fold.

摘要： A folding machine for folding sheet material comprises a housing defining a space and having an in-take opening and a discharge opening for sheet material before and after it is folded. A frame is provided in the housing and carries four rollers which are engaged with each other to form a take-in nip for receiving sheet material from the in-take opening, a first folding nip for executing a first fold on the paper and a second folding nip for executing a second fold of the paper. The rollers are engaged to each other by gears and are rotated by a single electric motor for moving the sheet material from the take-in nip to the first folding nip and from the first folding nip to the second folding nip. A pocket is formed upstream of the first folding nip in the housing for receiving the sheet of paper to stop its forward progress. The sheet of paper is continued to be fed by the take-in nip so that it folds into the first folding nip which draws the now once folded paper from the first pocket. A second pocket is provided downstream of the first folding nip to permit the second folding nip to form a second fold whereupon the folded sheet material is discharged through the discharge opening of the housing. The housing is formed in two articulated parts as is the frame so that the housing can be opened. Three of the rollers which define the take-in and second folding nips are connected to one part of the frame so that when the housing is opened these rollers are separated from the other roller. The housing and frame are designed to open on a plane which is near a tangential plane passing through the first folding nip. When the housing is opened the rollers and the pockets are exposed for removing paper that might have jammed in the folding machine.

摘要： 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.

摘要： 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. The parting lines of the vertical housing walls extend at least partly close to the plane of the folding pockets.

摘要： 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. The switch changes state when a selected relative position is established between the retaining member and the contact surface of the bracket. A circuit is connected to the switch for indicating its change in state. The selected position is chosen for establishing the correct passage gap for a sheet of paper to be fed.

摘要： A folding machine includes an entrance feed for the infeed of materials to be folded which are operated on by a plurality of folding devices arranged along the feed path, each of which feeds the material after folding into a receiving pocket which has an adjustable stop. The stop is adjusted so that the materials being fed are received in the pocket at the correct location so as to position them for subsequent folding or for ejecting at an ejection point. The invention provides a conveyor belt which operates so that an upper transport reach is movable below the ejection point to receive the folded materials. Associated with the conveyor is a brake element which overlies the materials which are fed on the conveyor transport reach. The brake element rests on the folding material and is mounted so that it applies a yieldable pressure on the materials as they moved therealong. A flexible member is connected between the brake element and the adjustable stop of the last folding pocket so that the position of the brake element can be adjusted relative to the ejection point by the same amount that the adjustable stop is adjusted in respect to its associated pocket.
