Definitions

  • the invention relates to a book-forming and -pressing machine with a plurality of rotating driven presses arranged at equal mutual distances from each other, each having a pair of press plates opposite each other with variable spacing for exerting a pressing pressure generated by spring elements on the pages of a book and with the pressing devices arranged heated fold forming devices, each having a pair of mutually opposing fold form rails for pressing in the book cover fold.
  • water-soluble adhesives are used to hang the book block into the book cover, the water content of which is used in the Abbin Deprocess of the adhesive migrates through the pressing of the book into the book cover and into the end sheets in order to evaporate there.
  • the task of a book forming and pressing machine is, on the one hand, to effect the setting of the adhesive in the shortest time unit via the pressing devices, for which purpose very high pressing forces have to be applied via the pressing plates;
  • the surface pressure goes hand in hand with the smoothing of the wet materials due to the glue application in order to keep them free of bubbles and wrinkles.
  • the book cover fold is formed at the same time as the pressing process, which takes place via heated profiled tools, often referred to as fold-in burn-in rails, which act on the cover material of the book cover between the back insert and the cover cardboard.
  • profiled tools are used to heat the cover material and make it more stretchable to achieve a permanent fold joint profile and also to achieve a firm adhesive bond between the book block and the book cover in the area of the fold joint.
  • a sufficient contact time of the heated tools is decisive for the shaping of the fold joint as well as for the setting of the adhesive applied more strongly in the fold area when hanging.
  • a bookforming and bookpressing machine is placed under protection which acts on a series of books, with a rotating head which can be moved about a vertical axis and on the circumference of which a plurality of pressing devices, each with a pair of opposing pressing plates, are arranged is.
  • the pressing devices Via the rotary head, the pressing devices pass intermittently into successive processing stations, in which there are fold burn-in devices, each consisting of a pair of opposed fold burn-in jaws.
  • fold burn-in devices each consisting of a pair of opposed fold burn-in jaws.
  • the fold-in device is closed to form the book cover joints and to apply heat to these areas.
  • the fold burn-in devices are located on the press devices and are clocked together with them.
  • the seam burners can thus be kept closed during the runout, which means that more time is available for the heat to act on the ceiling material.
  • a machine of this further developed type also referred to as a fold-in and pressing machine, is reported in the trade journal "Deutscher Drucker” No. 33 / 6-9-73, page 10, columns 3 and 4. It emphasizes that it is particularly important for heat-sensitive ceiling materials if the burn-in strips can be operated at a relatively low temperature, which is ensured by the number of processing stations.
  • a book press with pressing and beading stations in a straight line is known.
  • the pressing and beading stations are arranged in two parallel channels or passages.
  • the books are kept constantly clamped by a conveyor located between press plates and bead iron during the pressing and beading of the book.
  • the pressing plates and beading iron can be moved via actuating devices for their relative adjustment relative to one another for abutment on the side surfaces and on the areas of the books to be formed.
  • the transport system exerts a pressing process on the areas of the books not covered by the pressing plates.
  • sensitive cover materials for the book covers especially with lacquered or cellophane-covered covers, markings in the transition areas between the strips of the transport system and the press plates cannot be prevented.
  • the book press in straight double channels can only be used for a limited performance range. On the one hand, this is due to the intermittent mode of operation with the required intermediate transport, on the other hand, the number of workstations can theoretically be increased arbitrarily, but this would result in an unacceptable space requirement.
  • the object of the invention is to provide a book molding and pressing machine of the generic type, with which a substantial increase in the speed of work and an increase in quality in shaping the book cover fold and pressing the book over the entire surface can be achieved.
  • the press device Gen and fold forming devices of the book forming and pressing machine get along without setting work for fold forming and full pressing of books of different thicknesses.
  • the object according to the invention is achieved in that the pressing devices with the folding forming devices are continuously drivable along a closed orbit with deflection points, preferably from an endless conveyor running around two deflection wheels, the inner press plate being the Press devices runs along the orbit of the conveyor in guides and the outer press plate of the press devices can be moved parallel to this in the sense of a change in distance from one another, and that means acting on the outer press plate for closing and applying a pressing force between the press plates, means acting on the outer press plate for reducing the pressing force and opening and a drive device for actuating the folding mold rails in the sense of a change in distance from one another are provided.
  • the pressing device Starting from a machine with a press device, consisting of an inner press plate and an outer press plate with support rods which are guided in the inner press plate, and with compression springs between the inner press plate and end limits on the support rods for applying a tensile force to the outer press plate in Towards the inner press plate, the pressing device according to a further feature of the invention is characterized by a holding force for the pressure applied to the books between the inner press plate and a yoke connecting the supporting rods, by acting on the outer press plate, applying a pressing force to the books and by a spring element Applying the press stroke to the spring elements, starting from a control curve, via a pressure body acting force transmission device with a self-locking ratchet depending on the book thickness can be brought into blocking action automatically. It can be provided that the effective press stroke exerted by the force transmission device on the locking mechanism is adjustable.
  • the bookforming and pressing machine according to the invention offers the advantage of great variability in terms of pressing and folding molding. With any expansion, the machine meets all requirements, especially with regard to performance. A constant fold shape result is guaranteed by the precise movement of the fold form rails in connection with the temperature control.
  • the time between import and export of the machine is available for the processes of full presses and fold forms. The available time can be increased by increasing the number of pressing devices with associated fold forming devices, so the system can be adapted to the number of cycles.
  • the functions of full presses and fold forms are independent of each other, which allows absolute variability in the order and duration of the two functions. Folding form pressure and pressing force can also be built up in several stages.
  • the fold forming rails are controlled relative to the press plates, the movement of both fold forming rails relative to the press plates being the same, which ensures a symmetrical fold formation.
