The invention relates to a method for the sectional assembly of web pieces made of rubber embedded wires or similar pieces of track of the same width to form a long track, in which the edges of the ends of a piece of web and the web after alignment with a straightening bar in the Conveying level can be connected to one another with an overlap by gluing or a similar measure. Usually, the pieces to be assembled and the pieces assembled from the pieces Train transported on a conveyor level with any equipment for moving the pieces and the track are provided. The advancement of the web for winding on a roller and the approach new pieces to be added requires independently movable devices on the Funding level. At the point where the assembly takes place, the end of the web has to be connected to the one to be attached Piece or vice versa are aligned, which is usually done by an operator. Apart from that from the fact that the work is physically difficult for the operator with large pieces, it is not to avoid inaccuracies when aligning laterally and especially when overlapping, which have a detrimental effect on the further processing of the composite web. These Disadvantages appear regardless of whether the pieces are glued, welded or otherwise be connected to each other.

Methods and devices are already known in which the cutting of a web into pieces and assembling the pieces to form a diagonal strip web in a single or at least in several interrelated devices takes place, so that an alignment is looser Pieces is not required. The pieces are already being separated from the web by suction heads seized and inevitably moved on to assemble. Other assembling machines of the pieces use movable plates to grip and hold the ends of the web or pieces but no device for aligning pieces that are displaced from one another.

It is also known to form loops in the processing of webs, through which a supply of material is created is held when machining is carried out intermittently during continuous transport. These Although long loops can be straightened by hand due to the lateral mobility of the ends without Making bulges easier, but not a substitute for manual alignment. The invention is based on the object of a Ver method and device for section-wise Assembling of track pieces to form a track

¹ S drive and find a suitable device through which an automatic mechanical alignment of the parts is possible with great accuracy when the pieces are put together.
For the above method it is proposed according to the invention that at least one end close to the edge for alignment, in particular for alignment with the other edge, after interruption of the conveying movement shortly before contact with the alignment strip, arched out of the conveying plane transversely to the conveying direction and then for striking is released to the alignment strip.

The bulge is provided as close as possible to the edge of the web or piece and causes that the part of the piece or web lying between the edge and the bulge of the The rest of the part is free to move because the bulge allows the surface piece to go up to the front edge in all directions the plane can be moved and pivoted without the lying behind the bulge Part of the movements must be involved. Accordingly, it becomes a corrective movement of the edge the track or the piece possible in the area of a relatively small area. The size of the bulge and the area size of the independently movable end of a web and / or piece will be coordinated so that the restoring force that prevails in the bulge on can influence the movement of the end. It is therefore necessary that during the formation the loop or the like or at least at the moment when the restoring force takes effect, the straightening strip is brought into the area of the edge of the web or of the piece.

The invention also relates to a device for carrying out said method with devices for magnetic or pneumatic detection, holding, conveying and alignment of the

According to the invention, the conveyor level 1 of the device is proposed by gen that to form the bulges, the rollers fed a feeder 2 on which the Zuüber arranged on the conveying level and under this composition determined path pieces in the same way are, during the moderate distances to the end of the track section or on a special signal and suction nozzles assigned to the track or moved towards them.

In order to keep the machine device as small as possible, in which, through a partial cutting drawing and a great deal of control expenditure, to avoid a suction mouthpiece or organs, it can be seen in the context of a wide magnet 18 Ren proposal is appropriate that the forehead is. In front of the holding plate 17, a straightening strip 19 is located on the lower sides of the holding plates and is mounted so as to be displaceable over them. A second full-width retaining plate from the loading 20 is located below the track 16 and can be moved out precisely near the conveying level and preferably, like the retaining plate 17, are designed as permanent magnets with retaining elements. Around 35 equips. In front of the holding plate 20 there is also a possibility of straightening, with the aid of the device also bar 21 is provided, which is vertically displaceable to connect such pieces to a track, but whose edges run downward outside the area of the conveyed obliquely to the conveying direction , it is moved to level 1. , ··., Another suggestion expedient that the holding From F i g. 2 it can be seen that the straightening strips 19, plates and the straightening strips alone can be arranged at an angle 40 21 obliquely to the conveying direction, range from 5 to 90 ° to the conveying direction when the edges 22, 23 of the piece 12 and the path correspond to the angle the edges of the web 16 to be connected run obliquely.

They make the remaining part of the piece 12 movable. The end 28, which is then likewise to be subjected to a corrective movement via the Ar path 16, can trigger the moving cylinders 33 and 39 so that the ends follow the movements of the holding plate 17. If the end 28 is in a certain position to the light barriers, namely corrected sideways with the help of the holding plate 17 and lent in the correct assembly position, leveled off, then by a renewed stroke, the operation of the device is as follows:

according to requirements, it is possible to simultaneously provide the opposite side on the edge 22 with an adhesive spread by a similar device. After the device 52 has been shifted to the side, the holding plate 17 is moved in the conveying direction according to the arrow 15 through the working cylinder 31, until it strikes the stop 42 (FIG. 3). In this position of the holding plate 17 shown in FIG. 7, the edge 22 has overlapped the edge 23 to the intended extent. The working cylinder 37 is now put into operation, which, as FIG. 8 shows, moves the holding plate 20 upwards and presses the edge 22 onto the edge 23. The holding plate 20 can then be lowered again, and at the same time the holding elements can be brought out of action by the piston 26, since the piece has meanwhile been connected to the track. The holding plate 17 is moved back into the starting position by the work cylinder 31 after the holding elements have been pulled up and thus rendered ineffective. This in FIG. The process indicated in FIG. 9 enables the device again to convey the resulting web to the winding drum and, according to FIG. 1, to convey a new piece for the assembly process. The process is then repeated as described. Patent claims: 1.
