Abstract:
The invention pertains to a device for forming the spine region and/or the adjacent joint areas of a book case prior to casing-in the book block by means of a forming component that lifts the spine region out of the extended starting position relative to rails that hold down the case boards or the joint areas, wherein the forming geometry of the forming component can be varied by means of motor-driven adjustments, and wherein a separate adjusting drive is assigned to each of the elements that can be adjusted relative to the base element and form the book case.
Abstract:
In a device for cutting to length and feeding spine strips (3) for a case maker (1), a center strip conveying device (30) is provided that advances the spine strip material (5, 6) by the spine width (BS) transverse to the board feed direction (23) in a cyclic fashion. The spine width (BS) can be changed from work cycle to work cycle without accumulating additional waste. This can be realized because the previously required width sizing on the material web is eliminated.
Abstract:
A book binding machine for processing book blocks (3) features a transport system (2) with a plurality of book block clamps (40) for receiving the book blocks (3) that can be continuously moved along a closed circulation path and are coupled to a traction mechanism (63), wherein the traction mechanism (63) revolves around a driving wheel (55) and a deflection wheel and is tensioned by means of a tensioning device. Processing stations (70, 80) are arranged in the region of straight sections of the circulation path. The driving wheel (55) is driven by a gearless, rotative electric direct drive (50), wherein a first rotating component (53) of the rotative direct drive (50) is mounted or realized directly on the driving wheel (55).
Abstract:
A marking ribbon (2) is affixed to a book block (3) in that a partial book block (10; 10.1 . . . 3) with at least one sheet (8.3) has the marking ribbon (2) is placed on the top sheet (8.3) before at least one other sheet (8.4) is deposited on the partial book block (10; 10.1 . . . 3) with the marking ribbon (2) placed thereon during the additional gathering. The gathered book block (12) with the marking ribbon (2) is subsequently bound and trimmed on three sides at the non-bound edges.
Abstract:
In a binding-in machine (40) for pressing in and joint forming books (1), the invention proposes that the delivery device (45) features a book gripper (45.1) with a pair of opposite joint gripping rails (45.4, 45.5) that take hold of the books (1) in the formed case joints (1c) and the distance between which can be varied, wherein the formed and pressed-in books (1) can be removed from the pressing devices (41) with said book gripper. The books (1) are reliably separated from the pressing plates (41.1) due to the inwardly directed movement of the joint gripping rails and subsequently pulled out of the pressing devices (41). The gripped removal makes it possible to realize a secondary forming or stabilizing of the formed case joints and to produce a glued connection between the case and the book block.
Abstract:
In an apparatus for cutting to length sections of a spine insert (1) that is unwound from a supply reel and for bringing together the spine inserts with infed cover boards (8) in a roller applicator (5, 6) for the mechanized production of book cases, the invention proposes that the pair of cut length transport rollers (3.1) for drawing forward a defined drawing-off length (L) of the spine insert (1) and for positioning the spine insert in the cutting device (9) and the pairs of feed rollers (4.1, 4.2, 4.3) for transporting the cut-to-length spine inserts (1) into the roller applicator (5, 6) through a transport channel (2) can be driven independently of one another, wherein the pairs of feed rollers (4.1, 4.2, 4.3) can be intermittently driven in a cyclic fashion with a constant stroke (HZ) while the pair of cut length transport rollers (3.1) carry out the transport stroke (HS), that is variable due to the drawing-off length (L) and features a first motion segment (20a) for synchronizing with the transport movement of the pairs of feed rollers (4.1, 4.2, 4.3) and a second motion segment (20c, b) in which the pair of cut length transport rollers is synchronized with the pairs of the feed rollers (4.1, 4.2, 4.3) and transports the spine insert (1) together with the pairs of feed rollers.
Abstract:
The invention pertains to a method and apparatus for producing cases with rounded corners. According to this method, the corner edge (10) that protrudes in the region of a rounded corner (9) is initially uprighted and turned over and subsequently pressed on the cover boards (7a, b, c) together with the turning-over and pressing-on of the lateral edge (11a) of an adjacent lateral border, in the same station (1). The apparatus comprises at least one rounded corner tool (3) that is arranged in the same station (1) in the which the lateral edges (11a, b) of opposed lateral borders that lie parallel to one another are uprighted, turned over, and pressed on the cover. The rounded corner tool (3) can be moved (b) toward the center of the case and out of the effective range of the lateral turn-in device (24) immediately before the turning-over and pressing-on movement (c, d) of the lateral turn-in device (24).
Abstract:
The disclosed device includes a feed conveyor (2), on which printed products (6) are transported within certain distances from one another, a turning section (1) with a path guide arranged tangentially downstream of the feed conveyor and a delivery conveyor (4) for the turned printed products (6) that extends underneath the feed conveyor (2) in the opposite transport direction. Lateral guides (12) are assigned to the path guides (13) and can be adjusted to the format width of the printed products (6). The delivery conveyor (4) is a suction conveyor belt with at least one suction segment (19) in the region of the delivery point of the turning section (1) in order to decelerate the printed products (6) to the transport speed of the delivery conveyor (4).
Abstract:
The invention relates to a device for feeding book blocks, books or similar printed products (2), in step with the working cycle, to a subsequent processing machine. The infeed device comprises a continuous-drive accumulating conveyor (3); an arrestor (5), arranged at the downstream end of the continuous-drive accumulating conveyor (3), for cycled release of individual printed products (2); and a continuous-drive onward conveyor (11), which transports the printed products (2) by means of frictional force, for onward conveying of the separated printed products (2) to a defined transfer position (13) from which the printed products (2) are taken over, in step with the working cycle, by an infeed system (17) of the subsequent processing machine. According to the invention, the infeed device is characterized by a sensor (14), arranged in the conveyance region of the onward conveyor (11), for registering the front edge of each printed product (2); and by an infeed control device (8) for evaluating the sensor signal and for triggering the arrestor (5), wherein the time difference between the remaining processing time (from receipt of the sensor signal to the point in time when the printed product (2) is taken over by the infeed system (17)) and the theoretical transport time to the transfer position (13) (given by the conveyance speed and the conveyance distance still to be traveled) is determined; and wherein the point in time for triggering the arrestor (5) in the subsequent conveyance cycle is correspondingly corrected by the time difference. This leads to the printed products (2) being taken over by the infeed system (17) of the subsequent processing machine almost at the point in time when they arrive at the transfer position (13).
