  • the invention consists in the use of a slot nozzle for the delivery of radiation-curable binder in combination with the adjacent arrangement of a radiation source for curing this binder.
  • a slot nozzle which is already known per se (eg from DE 195 18 604 A1 and the corresponding US 5,126,993,993), allows a targeted metering and a targeted order substantially over the entire width of the narrow side to be bound the stack or the book spine to be bound, so that no more binder than necessary is consumed.
  • the low consumption of binders to be realized with the invention also results from the fact that the slot nozzle is usually part of a so-called closed system.
  • the use of a slot in a closed system is less susceptible to dust and dirt, which is precisely in the field of application here of great importance, since usually just before binding the narrow side of the stack to be bound by means of cutting tools and / or by milling or a other machining is prepared accordingly.
  • the application area of the binder on the narrow side of the stack or the spine can be specifically and thus illuminated with the desired intensity, whereby a targeted and thus rapid hardening of the applied binder can be realized.
  • the construction according to the invention not only leads to higher quality and economical energy consumption, but also to a space-saving design of the entire device.
  • the construction according to the invention which can also be retrofitted to any conventional binding device, both the production costs and the operating and maintenance costs can be reduced.
  • the binder is curable by ultraviolet light radiation and thus the radiation source is a source of UV light rays.
  • the radiation source is a source of UV light rays.
  • this polyurethane is used.
  • a further preferred embodiment of the invention is characterized in that the radiation source is in a fixed relative position to the binder application device.
  • the desired targeted irradiation of the binder application area on the narrow side of the stack can be realized with particularly high accuracy.
  • the radiation source should also be attached to this holder, whereby the desired fixed relative positioning is made possible in a particularly simple manner. If a housing substantially receiving the binder application device is provided, the radiation source should also be arranged essentially on and / or in such a housing in order to achieve the desired fixed relative positioning in a particularly simple manner.
  • a water cooling device should preferably be used for this purpose.
  • the application of the binder is completely unaffected by water cooling.
  • a water cooling leads to any dust and dirt, so no exhaust filters or the like. and is therefore virtually maintenance-free.
  • the source of radiation can be cooled in a particularly targeted manner, and the demand for a space-saving design of the entire apparatus is met. versus.
  • the use of water cooling forms another important preferred aspect of the invention.
  • a diaphragm which can be moved into the beam path of the beam generated by the radiation source can be provided, whereby the light beam and thus the effect of the radiation source can be interrupted almost without delay.
  • This can not be achieved in such a short time with a normal switching on and off of the radiation source, since, in particular, when the radiation source is switched on, it usually takes a certain time before it takes full effect.
  • frequent switching on and off leads to increased wear of the radiation source.
  • this embodiment contributes to an increased processing speed.
  • a holding device for holding the stack should be designed such that the stack with its narrow side to be bound can be positioned substantially above the binder application device.
  • the radiation source may be arranged and configured so that the beam generated by it is directed upward.
