BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase application of PCT/DE91/00118 filed 14 Feb. 1991 and based upon a German Application G90 02 121.5 filed 22 Feb. 1990.
FIELD OF THE INVENTION
The invention relates to a device for applying fabric webs or lengths of fabric, particularly of fabrics covered by pile on both sides, with a pile-free area (smooth-woven fabric) adjacent the pile area, in order to feed the fabric webs or lengths of fabric to hemming and sewing stations equipped with a conveying device consisting of a pair of belts.
BACKGROUND OF THE INVENTION
The concept "covered by pile" applies to any desired thickening of a fabric, such as terry cloth, looped or tufted fabrics or the like. In the processing of such goods difficulties have arisen, particularly during hemming and sewing, since it is difficult to obtain a hem or a seam precisely applied to the pile edge without particular care from the operator. However, the latter costs time and money.
OBJECT OF THE INVENTION
It is therefore the object of the invention to provide a device for applying such fabric webs during hemming and sewing, so that the seam to be formed will run precisely along the pile and that no pile loops will be stitched into the seam.
SUMMARY OF THE INVENTION
The device according to the invention includes an upper runner resiliently mounted on an intermediate device and a lower runner rigidly mounted on a frame. A step-like formation provided on respective running edges of the runners is a simple and cost-efficient way to process terry cloth to be hemmed. The stitching of pile loops is certainly avoided. The device is operated at allows high operational speeds with low skill requirements for the operator. The device can work with a tolerance of about 4 mm with respect to the reference line when inserting the fabric web, because the edges of the runners are shaped so that the pile is always pushed back from the pile-free area.
BRIEF DESCRIPTION OF THE DRAWING
The above and other objects, features and advantages of the invention will become more readily apparent from the following description, reference being made to the accompanying highly diagrammatic drawing in which:
FIG. 1 is a lateral elevation view of the device according to the invention;
FIG. 2 a top diagrammatic view of the device shown in FIG. 1;
FIG. 3A is a cross sectional view along line III A--III A shown in FIG. 2;
FIG. 3B is a cross sectional view along line III B--III B shown in FIG. 2; and
FIG. 3C is a cross sectional view along line III C--III C shown in FIG. 2.
SPECIFIC DESCRIPTION
FIG. 1 shows the device in a side view. It is designed as an intermediate device 8, preceding a conveying device 9 and fastened via a bracket 5 to the machine frame. An essential part of the device are two runners 1, 2. The runner 1 is a rigid support under the fabric web 10 and the runner 2 is resiliently suspended on the intermediate device 8. The contact pressure of runner 2 can be varied by means of screw bolts 4 acting upon springs 3. The conveying device 9 consists in a manner known per se of two endless belts 6, 7, which at their contact surfaces take over the fabric web 10 and move in the direction of arrow 13 towards a hemming and sewing station (not shown in the drawing). The fabric web 10 to be inserted is introduced manually between the two runners 1, 2. Beyond the runners 1, 2, the fabric web 10 is taken over by the belts 6, 7 of the conveying device 9, whereby the plane between the two runners 1, 2 and the two mutually touching belt segments 6, 7 are at the same level.
FIG. 2 shows a top view of the device. The fabric web 10 consisting of a pile area 11 and a pile-free area (smooth-woven fabric) 12 has a pile edge 14, along which the goods are supposed to be hemmed and sewn. In the top view the runner 2 can also be seen, while the runner 1 located underneath is covered by the fabric web 10. The runners 1 and 2 are basically identically shaped, however the lower runner 1 can be shorter. Respective edges of the runners
