Definitions

• the invention relates to a device for producing bound documents with representative covers, whereby texts, magazines, constructive representations, image collections, contracts, offers, advertising material (catalogs) in an appealing form, in small to medium series can be brought onto the market.
• the application is intended for private and commercial use, in particular for work in architecture, engineering and construction offices, as well as in tax consulting and law firms and also schools, administrations or advertising agencies.
• the Swiss patent specification CH 677053 A5 presents a device for binding sheets by heating, an aluminum rail with recesses for heating elements being arranged in the interior of an octagonal housing.
• the device allows two folders to be bound at the same time, and the switching duration of the PTC heating elements can be regulated in time using built-in electronics.
• the compact design has the advantage of being easy to use, but on the other hand the disadvantage that the cycle times between heating and cooling are high and energy is "wasted". Additional ventilation slots in the bottom of the housing are proposed to reduce this time disadvantage.
• the US patent application 5 829 938 also presents a heatable table device with which a given paper stack is “gripped” by means of an L-shaped binding tape wetted with adhesive after insertion and electrical heating and then by manual swiveling in the sense of “folding” short pressure is applied in the area to be glued.
• a given paper stack is “gripped” by means of an L-shaped binding tape wetted with adhesive after insertion and electrical heating and then by manual swiveling in the sense of “folding” short pressure is applied in the area to be glued.
• the object of the invention being to improve the energetic conditions of known binding devices, to enable binding of bindings made of metallic or non-metallic materials to be made equally possible and also with a technique which optimally controls the binding time enable different formats of sheets or sheets to be bound, with no restrictions on usable binders.
• the central element of the binding device is an elongated and inherently stable ceramic surface that can be quickly heated and cooled, and on the underside of which a heating element is attached.
• the inductive sensors which are arranged in pairs or several, which are located under the ceramic surface, trigger the heating of the ceramic surface when inserting a binder, up to the optimal softening point of the adhesive material deposited in the back of a metallic cover, whereby thermal sensors distributed over the heating surface of this ceramic surface monitor Act. This prevents incorrect bindings by means of precisely specified temperatures and control times, which can be regulated electrically, and prevents warping of the book cover due to overheating from the outset.
• folders can also be produced that are designed in a different way, namely manufacture from plastic materials, cardboard or from laminated materials.
• the heating contact can be initiated or activated by actuating an optical or microswitch (button). can be switched off at any time by means of the measurement using the existing thermal sensors.
• Another sensor that partially emerges upwards in a transverse gap in the ceramic heating surface is in electrical contact with a contact wire / resistance wire when subjected to load, which means that measured in terms of the width of an arbitrarily obtained cover or its weight with the ones to be bound Scrolling the electrical resistance can be detected microelectronically and supports the heating and switching-off process of the thermal sensors by determining the required heating time.
• the inside of the sensor has an arranged hose along with an adjustment facility for setting a defined pressure, the load introduced by inserting a cover being in operative connection with a pressure-sensing sensor and / or switch. The latter then triggers the start of the heating of the ceramic heating surface.
• the position of the sensor can be provided in the center of the ceramic heating surface or at the end of the same, a stop forming the end of the ceramic heating surface in the latter.
• the heating surface is transported in such a way that a built-in
• the time for heating can also be controlled by a pressure sensor depending on the different weight of the binders.

• the ceramic heating surface 1 is located in a thermal binding device on the upper side of the housing 5. In order to support the sheets 14 to be bound together with the cover 13, retaining brackets 23 are provided in pairs above the lateral ceramic heating surface 1.
• the ceramic heating surface 1 on the underside of which a heating element is integrated or a Peletier element is attached also has on its underside one or more inductive sensors 3 and thermosensors 2 which on the one hand trigger the heating process and on the other hand after the optimum melting of the binding adhesive and sinking in of the Sheets 14 in the existing cover 13 switch off the heating process.
• microswitches or optical sensors which can be acted upon via a crosspiece 15, are alternatively used.
• the pressure sensor 22 determines from the weight of a folder the associated binding width and the binding time required for this at a predetermined binding temperature.
• the wire coil 8 also serves the same purpose when the contact wire / resistance wire 10 comes into contact as a result of loading by the binder.
• the changed resistance in the contact wire / resistance wire 10 is used as the width of the binder for heating control.
• the stop 9 is located next to it.
• the flexible hose 6 with a piston 11 and the adjusting screw 12 for adjusting the output signal is also arranged under the wire coil 8.
• a / or a row of piezo elements can be arranged on its underside, which promote the sinking of the sheets 14 into a cover 13 by oscillation and vibration during the melting of the binding adhesive.
• one or more motor fans 4 are positioned below, to the side of the ceramic heating surface 1, the air currents generated only reaching the cover / covers 13 by means of a pivotable, motor-operated cover plate 19 and the residual heating energy of the ceramic heating surface 1 is not attacked if possible ,
• the drive for the cover plate 19, i.e. the motor is marked with the position symbol 20.
• the ceramic heating surface 1 can additionally be pivoted off by means of a motor 21.
• the cooling process is advantageously designed to be able to be forced in time in the vicinity of the covers 13 by switchable Peltier elements. It can be provided that a transverse web 18 serves as a mounting surface for the binding material, in the event that the ceramic heating surface 1 is designed to be laterally displaceable for the purpose of cooling.
