- Intermediate carrier tapes are used in electrographic printers or copiers to generate latent electrostatic images and / or to provide a carrier for toner images to be transferred.
- an endless belt with a photoconductive layer e.g. an OPC tape (organic photo-conducting) is used, which forms a corresponding electrostatic charge image, a so-called latent charge image, by exposure according to a predetermined image pattern.
- This latent charge image is then colored with toner material in a developer station; this toner image is then later transferred to paper or another recording medium and fixed there.
- An endless intermediate carrier belt can also serve as a transfer belt to collect toner images and to forward them to a transfer printing location.
- a first toner image of a first color is transferred to the intermediate carrier belt.
- a second toner image is then etc transmitted with a second color on this first toner image ..
- the superimposed so each other ⁇ , multicolor toner images on the intermediate carrier tape are then conveyed to a transfer point and transferred there to the recording medium and fixed.

- Hot Plate Welding it is known to firmly connect plastic parts to one another by butt welding.
- a heating element is placed between the contact surfaces of the parts to be welded, which are opposite each other, and the contact surfaces are heated until the melting phase. The heating element is then removed and the opposing contact surfaces are pressed against one another.
- An overlap welding method is known from the above-mentioned Internet information with the titles "Through-transmission Infrared Welding TTIR" or "Infrared Heating”.
- the ends of plastic parts to be welded are placed one above the other and heated by infrared radiation or laser radiation from a radiation source not in contact with the parts to be welded until the melting phase.
- One application of this method is the welding of a part which is transparent to the radiation to a part which is opaque to the radiation, the welding occurring in the region of the adjoining surfaces of the parts to be welded.

- the pressure surfaces are at a distance from one another which is determined by the thickness of the cold plastic film.
- the adjoining ends of the plastic film are heated, the melted mass cannot become thicker than is predetermined by the distance between the two pressure surfaces.
- the cooled weld seam along the entire width of the plastic film has the same thickness as the plastic film itself.
- the weld seam therefore has no raised shape and is only subject to a lot of use of the endless belt as an intermediate carrier belt in a printer or copier. low wear.
- the weld seam is so uniform that this area can be fully used as a functional surface when functioning as an intermediate carrier tape.
- the area of the weld seam can be covered with a photoconductive layer within which latent image structures are formed by exposure.
- this area can be used as an intermediate carrier belt for the transfer of toner images, for example also superimposed toner images, this area can
- Welding point can also be used. The result of this is that an endless intermediate carrier tape produced in this way can be fully utilized on its surface, as a result of which its total length can be short and there are further structural advantages in the construction of the printer or copier.
- the plastic film has at least the width of a standard print format, i.e. at least the width of a DIN A4 sheet.
- the pressure surfaces must also be designed accordingly in the respective length. Due to the guidance through the pressure surfaces, it is possible to produce a uniform and functional weld seam along this relatively large width.
- the force exerted on the contact surfaces must be determined empirically. It depends on the type of plastic film, the thickness of the plastic film and the length of the weld seam to be produced.
- a device for producing an endless belt made of thermoplastic material for an intermediate carrier belt in an electrographic printer or copier is specified.
- the advantages that can be achieved with this device correspond to the advantages described in the method.
- the invention is explained in more detail below using exemplary embodiments according to the figures of the drawings. It shows:
- Figure 1 is a schematic representation of a first embodiment of a device according to the invention.
- FIG. 2 shows a schematic illustration of a second exemplary embodiment of a device according to the invention.
- FIG. 3 shows a schematic illustration of part of a device according to the invention, which can also be used in the exemplary embodiments according to FIGS. 1 and 2,
- FIG. 4 shows a schematic illustration of an inventive device according to FIG. 1 with two absorption devices as a fourth exemplary embodiment
- FIG. 5 shows an absorption device consisting of stainless steel sheet with an absorption layer
- Figure 6 shows an absorption device with a transparent glass pane, a DLC layer and a non-stick coating.
- a thermoplastic plastic film 10 is inserted between a transparent holding element, for example a glass pane 11, and a transparent counter-holding element, also for example a glass pane 12, in such a way that the ends of the film lie flush against one another at the end.
- a transparent holding element for example a glass pane 11
- a transparent counter-holding element also for example a glass pane 12
- Pressure frames 13 and 14 are provided, which exert a predetermined force F on the glass panes 11, 12 and thus on the plastic film 10.
- the flat surfaces of the glass panes 11, 12 abutting the plastic film 10 form flat pressure surfaces 11a, 12a.
- these pressure surfaces 11a, 12a can also be concentric, for example cylindrical surfaces.
- the corresponding glass panes are then cylinder jacket elements.
- the plastic film has a width of at least the width of a standard print format, for example DIN A4.
- Glass panes 11, 12 have a length that is greater than this width.
- Radiation conductor fibers 15 and 17 and focusing optics 16 and 18 supply radiation from heating sources (not shown) for heating the plastic film 10 in the region of the film ends lying against one another to beyond the melting point. This creates a weld seam 19 between the ends of the film.
- the radiation sources are preferably laser radiation sources, such as diode lasers, solid-state lasers, gas lasers or laser diode arrays. Depending on the absorption capacity of the material of the plastic film 10, a certain part of the radiation is absorbed and converted into heat.

This distance is maintained when the ends of the plastic film 10 are heated and melted, i.e. the force F is chosen to be correspondingly high. The melted material is then distributed along the butt-jointed ends with a thickness corresponding to this distance.
- the thickness of the plastic film 10 and the radiation supplied by the radiation source 15, 16 are matched to one another such that the optical penetration depth of the radiation is less than or equal to half the thickness of the plastic film 10. This ensures that sufficient energy can be supplied to the plastic film 10 in order to be able to weld it correctly.
- one of the holding elements 11 and 12, preferably the counter-holding element 12, can preferably be designed to be reflective on the relevant pressure surface 12a. Then transmitted radiation is reflected back into the plastic film 10.
- the support element 12 can e.g. be designed as a mirror or as a polished metal sheet, preferably a copper or aluminum sheet, or comprise a reflection-coated material.

- the plastic film 10 can also be turned over so that irradiation takes place from both sides in succession.
- an additional clamping of the plastic parts 10 is provided with the aid of a fixed clamping element 30 and a movably mounted clamping element 31 , The movement of these clamping elements 30 and 31 for pressing the ends of the plastic film 10 together is indicated by an arrow A.
- both the clamping element 30 and the clamping element 31 can be movably mounted. With the help of the clamping elements 30, 31, the quality, in particular the strength of the weld seam, can be improved by pressing them together.
- the device according to the invention can be moved with the plastic film 10 fixed in it with a linear table in the direction perpendicular to the plane of the drawing under the focused radiation. It is also possible to move the radiation over the film area to be welded and fixed in the device according to the invention.
- the radiation source i.e. the radiation guide fibers 15 and 17 as well as the focusing optics 16 and 18 can be designed to be movable.
- the radiation can also e.g. distracted with a galvanometer mirror or e.g. can be expanded with line optics. In the latter case, simultaneous welding over the entire width of the film is possible.

- the absorption device 40 is located directly between the holding element 11 and the plastic film 10 and forms the first pressure surface 11a.
- the absorption device 42 lies directly between the counter support element 12 and the plastic Fabric film 10 and forms the second pressure surface 12a.
- the side of the absorption device 40, 42 which faces the radiation source 16 or 18 respectively absorbs the emitted radiation energy and converts it into heat which is passed on to the opposite ends of the plastic film 10 and which brings about the welding.
- any thermoplastic material can be used regardless of the particular absorption property, for example completely transparent plastic film.
- the absorption device 40, 42 consists of a thin metal sheet, for example CrNi steel sheet, which is arranged between the plastic film 10 and the holding element 11, 12.
- the side of the metal sheet 52 facing the irradiation side can be roughened for the purpose of improved absorption or can be provided with an absorbent coating 50, in particular with black chrome or stove paint.
- the absorption device 40, 42 consists of an absorbent layer 62, in particular a hydrophobic DLC layer or a hard material layer, preferably each with a thickness of approximately 0.2-3 .mu.m, on a transparent glass pane 60 serving as a carrier Glass pane 60 simultaneously takes over the function of the holding element 11 or 12 (see FIG. 4).
- the absorbent layer 62 can additionally be provided on the side facing away from the radiation with a non-stick layer 64, in particular a DLC coating, Teflon or silicone, preferably with a thickness of approximately 0.5-3 ⁇ m. This prevents the plastic film 10 from sticking during the welding process.
