Device for folding the longitudinal edges of continuous textile webs

The invention relates to a device for folding the Longitudinal edges of continuous textile webs, especially large ones Fold width, consisting of a U-shaped profiled, fixed to the frame, in the direction of transport of the textile web Bich extending and the fold encompassing folding sheet in which a closed, frame-fixedly held, in the textile web fold engaging folding plate is arranged.

In the case of a known only from operational practice, such a folding device from which the invention is based, and those for the production of SMumen, especially of fine grains 2 cm wide and more is required, the edge of the textile web before it enters the folding device to be continuously pre-folded by hand and fed into the folding device to ensure a constant width Get crease. Ultimately, however, it is particularly in the case of textile webs with poor seams, fine fabrics and / or large ones Hem widths of, for example, 5 cm wide do not ensure that a warp-free fold is achieved.

The object of the invention is now to create possibilities in a device of the type described above for manufacturing

Warp-free, especially wide s urn in use manual aid measures can be dispensed with more easily do.

The solution to this problem is characterized according to the invention in that the inner folding plate to the textile web transport direction parallel over the sweeter folding plate arranged on the front side protruding, and that a frame-fixed, Motorized rotating and lowerable on the above folding sheet metal brush is arranged, the The axis of rotation runs parallel to the direction of transport of the textile web is arranged.

These measures now mean the circumferential Round brush the folding edge continuously aligned in the correct position and at the same time also solidified without a manual Action is required.

It is advantageous to ωεηπ the above part of the inner folding plate of the textile web transport direction opposite is arranged.

A preferred embodiment of the above-described folding device , which also applies to textile webs with extremely poor seams ensures a distortion-free folding, is thereby

characterized in that the inner folding plate is also channel-shaped is profiled, is arranged in the same direction as the outer folding plate and at a constant distance from it and one protruding over the sweeter folding sheet on the front side, the corresponding part with the round brush, whereby preferably also the leg facing away from the folded edge of the inner folding plate is formed protruding on the front side over the outer folding plate.

Another, advantageous, particularly simple measure in the above-described subject for adaptation to the respective Characterizes the seaming behavior of the textile web to be seamed and the intended change in the seam width by measuring the distance between the round brush and the inside Folding sheet optionally adjustable adjustment device.

In addition, it is advantageous if the brush can be adjusted parallel to the textile web and transversely to the folded edge Adjusting device is arranged.

This has the advantage that the rotational speed of the Round brush may remain constant.

To also in every case, for example in the case of irregular napped d.M. Textile webs to ensure a constant hem width is characterized by an advantageous one Further development of the subject described by motorized edge scanning devices that operate without contact controllable brush actuating devices.

In addition, it has proven to be advantageous if the round brush has a diameter that is approximately the width of a double folded sheet metal.

An embodiment of the invention is in the drawings and is described below.

in which a folded plate U, profiled similarly to the latter, is arranged and connected to the folded plate 3 by means of two webs 5.

A part of the leg 6 of the folding plate h , which is otherwise arranged flush on the inside with the folding plate 3, is formed protruding in the opposite direction to the tranaport direction of the textile web 2.

Opposite this protruding folded sheet metal part 6, a motorized rotating round brush 7 is held fixed to the frame, whose axis of rotation θ to the transport direction of the textile web 2 is arranged to run parallel.

AIb drive is an electric motor 9 is provided on a Slide 1D of a cross support 11 that is fixed to the frame is attached.

With the carriage 10, the distance between the round brush 7 and part 6 of the folding plate k can be adjusted. The second slide 12 of the cross support enables the brush 7 to be adjusted parallel to the plane of the textile web 2 and transversely to its transport direction.

Below the folding device is an optically effective one Textile web edge scanning device 13 supported gestellfeat, which causes a shutdown of the textile web transport, provided that the fold width reached is the desired Wrinkle width deviates.

The scanning device 13 is for adjusting the slide 12 designed to be adjustable in parallel (not shown). In order to increase the throughput rate, it is advantageous to assign at least the carriage 1D a motorized adjusting device which can be controlled by the scanning device 13, whereby maintenance of the specified value is ensured without manual intervention being required for this purpose.

One leg H * of the folding plate 3 protrudes laterally beyond the folding plate k .
