Perform this procedure.

Description!

1.) The subject matter of the invention is a method and a device used to carry it out for the production of flawlessly cut-offs Curtain fabrics and simultaneous attachment of a hanger edge that ensures an even sewing of the hem.

2.) Ss methods are known curtain fabrics with auxiliary devices cut off, but not in a hanging position and with this accuracy that by parallel guidance of the cross rails in those the knives for cutting the fabric are guaranteed.

5) The invention is based on the object of using a method that guarantees precise, flawless cutting of curtain fabrics.

Inaccuracies in cutting the fabric mean that the curtain does not sag evenly after opening. The invention is based on the object of using a method which has this disadvantage avoids.

The advantages of the invention are particularly significant when there are several curtains that are all the same size, or if there are fabrics with larger dimensions.

k.) A process that can be used to carry out the method is shown in the drawing.

5 ·) The device, consisting of the frame "r" in width and height about Jm, two brake motors "i", the drive shafts "k" that run in screwed-on bearing blocks, and the toothed belt rqdem on which the toothed belts "d" and "e run which ensure an accurate transport of the crossbars a and b ". The guide rails "c" take over the exact lateral guidance.

6.) The work process

The bar "a" is brought to the working height that was previously with the

" h" at which the dimensions in the direction of the line "a" me "h"

are registered. At the desired point on the measuring tape, dfi

Shut-off pin for the limit switch of the bar "b ·· clamped, then the transport is switched on in the direction of the shut-off pin for strip "b", whereby it should be noted that the otherwise exposed Nail strips "η" and "ο" now through a protective flap are covered.

The bar "b" then remains in the desired position, the protective flap is opened so that the fabric is now on the Nail strips "η and ο" can be knocked open. Has this happened so the fabric can be cut to the exact length by the ripping machine "f" which is now done by hand from the starting position from the right pushed to the left will be cut off. Me ripper is precisely guided by a ball machine.

When the cutting process is finished, an edge for the hem is ironed into the curtain material, which is still hanging on the nail bars "1 and η", using a bracket device on the bracket bar "m". Once this has been done, the fabric is ^{removed from the Nt-rail bar 11} η ", the bar '· a" is moved to working height and here too the fabric is removed from the needle bar "1". The curtain fabric is now ready for sewing aes hem.

Claims (1)

'S Claims 1,) Method of making flawlessly cut curtain fabrics with simultaneous attachment of a bracket edge for the hem of the curtain. 2,) Device for carrying out the method according to claim 1 characterized due to the precise height transport of the cross bars a and b through the toothed belts d and e, the precise lateral guidance the transverse strips also over larger widths through the guide rails c, as well as the bracket edge strip m on the transverse strip b and the fabric fastening on the crossbars a and b through the nail strips 1, η and o. 1098'i 7/0343 Leeward
