Definitions

• the invention relates to a process for the production of textile thread images, in which differently colored and / or different-like thread sections are arranged and fixed perpendicular to the image plane in image pattern foils, in each case the threads that are required for one image line are drawn off from storage holders and parallel to one another in one plane be arranged on a field length that corresponds to a multiple of a thread section length, the thread layers produced for the individual image lines are stacked one after the other, all thread layers of an image are layered and fixed to one another and the thread block is cut into image fields in slices perpendicular to the thread direction
• Such a method is known from DE-AS 20 22 263.
• the threads of a thread layer are individually woven one after the other as weft threads in a warp thread arrangement, which requires a high amount of machine time.
• the resulting tissue web sections are only held at the edges, while they are stacked on top of one another for cutting into image fields. This fixation in the tissue and on the edges provides only a limited point accuracy of the threads in the image plane.
• the solution to the problem is that the threads arranged in parallel correspond to the respective image line are fixed at their r eld rotating and their End field in their position to one another on a support releasably and then the Felde ⁇ den be cut, and the cut image frames are each tillkelbt with a cutting side, a protective plate, the stacked Fadenlage ⁇ fixed, and by an adhesive to each other their carriers are removed .
• the method is advantageously carried out in such a way that the field adjoining one thread layer, catch of a similar further thread layer, is glued together with the end of the preceding fade, after which the field end of the beginning of the field is separated, whereupon the finished thread layer is fed to a supply stack and the beginning of the field of the subsequent field is pulled up by a field length, the threads being drawn off in parallel from the supply holders.
• the threads are expediently pulled through a guide gate which lies behind the end of the thread field and keeps the threads in the required parallel distance.
• the thread ends can be fixed in each case between clamping tabs at the ends of the carrier plates, or it is preferably carried out with adhesive strips which are easily detachable from the carrier plate and are further used in the formation of stacks.
• a transverse layer of relatively distant transverse threads or transverse paper strips can be inserted and glued there, these transverse inserts preferably being close to or in the later cutting planes that are are directed towards the protective plate.
• the stacking is preferably carried out by means of a device consisting of a table with a wedge gauge and storage holders for the transverse threads or strips and guide gates for these.
• the product produced by this process is completely new and of high image quality.
• the images can also be processed in mirror image on the border.

• the thread sections (1) are arranged one above the other in a line-shaped thread section layer (10, 11) and connected to one another by adhesive.
• Cross threads (30, 31) are inserted between the thread section layers (10, 11) and are also glued. In the example shown, a cross thread is only inserted between every second layer.
• the rear thread section ends are attached to the protective plate (2) with an adhesive layer (21).
• the thread image is framed with a frame (20), which can be equipped as desired in the manner of a picture frame, but preferably has at least a depth of half the length of the thread section in the contact area (22) so that it forms a defined closure .
• the various symbols shown in the figure on the front of the image symbolize the different thread colors from which the image results.
• Fig. 2 shows a sub-device with which the Fade ⁇ lagen (50, 51) are produced as an intermediate. It consists of a table (4) on which the apple side, preferably offset downward, arranges container A for the yarn balls of the different types of yarn. are. Edge strips (42, 43) are attached to the sides of the table (4), between which the support plates (45, 46) can each be inserted and moved in the longitudinal direction of the table. A cutting joint (49) is introduced between the two carrier plate positions, which adjoin one another in the longitudinal direction of the table, and a cutting ruler (47) is attached transversely above the table (4).
• the individual threads (5) of the supply balls in the supply containers (41) are each carried out individually between two creel pins (40) of a gate which is arranged on the head side of the table (4) and oa: llel to one another via the carrier plates (45, 46) over the table length.
• an adhesive tape roll (44) is arranged adjacent, the center of which is aligned with the end of the carrier plate (45).
• the parallel pulled threads (5) with the adhesive strips (54, 55) from the roll (44) are releasably fixed to each other and with the carrier plate (45) and with the separator (48) cut off from the roll (44).
• the adhesive tape section (52, 53) the is fixed to the threads (5) and the carrier plates (45, 46) in the intermediate region of the two carrier plates (45, 46), passes along the cutting ruler (47) together with the threads (5), so that the thread layer (50), which is fixed on the end carrier plate (46) with the adhesive strip section (52) can be removed.
• the remaining gate-side carrier plate (45) is then pushed further by a carrier plate length, the threads (5), which are attached to it with their adhesive strip sections (53, 54), being retightened.
• a free carrier plate is then pushed into the gate-side position.
• the adhesive strip area (55), which had previously only adhered to the threads, is then fixed to this new carrier plate; it is then in the former position of the adhesive strip area (53), which has been pushed forward by a corresponding length of the carrier plate.
• the process step described is then repeated.
• the finished thread layers (50) are fed to the intermediate plates with the carrier plates (45, 46) and from there fed to the further sub-device for block formation.
• Fig. 3 shows the partial device for producing the Faden ⁇ blocks from the thread layers (50) in plan.
• a stop wall (64) is attached to the table (6) at one end and is used to support one end side of the thread layer (59).
• two rows of vertical limiting rods (61, 62) are placed on both sides of the table (6) against which the thread layers (50) lie laterally.
• a row of storage containers (63) for transverse threads (30) is arranged.
• a pair of the delimitation bars (62) with a passage gap for a transverse thread (30) is preferably arranged next to a storage container (63).
• the limiting rods (61) are each assigned to the passage gap, so that a transverse thread (30) can be aligned perpendicular to the direction of the threads (5).
• an adhesive layer is applied, for which a spray application is preferably used. Then the adhesive strips (53, 54) removed.
• Fig. 4 shows the sub-device for producing the thread blocks in vertical section after the insertion of the first thread layer (50) between the stop wall (64 and the limiting rods (61, 62), and after the transverse drawing _ ⁇ transverse threads (30).
