Application Marcus, 1932; Serial No. 597,085

3 Claims. K01. 223-15) i This invention relates to improvements in device for folding and initially hot-pressing marfor theapplication of heat or the hot-pressing of a such marginal edges for the purpose of causing the same to be retained in turned or folded position.

Another object of this invention is to produce a device which in one operation accomplishes the functions of opening up the slit between parallel rows thereof in a fabric, turning and folding down the marginal edge or edges of such fabric, and ironing or hot-pressing the same to cause the folded edges to be retained in folded position.

With these and other objects in view, the invention comprises the combination of members and arrangement of parts so combined as to coact and co-operate with each otherin the" performance of the functions and the accomplishment of the results herein contemplated, and comprises in one of its adaptions the species or preferred form illustrated in the accompanying drawing, in which:-

'Fig. l is a view in plan of a piece of material orjfabric used in faggoting embroidery and superimposed upon apiece of vanishing fabric having a design stitched thereunto with a faggoting stitch and showing the fabric slit and the tool in the act of turning the edges;

Fig. 1 is a section on the line I* l of Fig. 1;

Fig. 2 is a side elevation of the device or tool; Fig. 3 is a bottom view of the tool shown in Figs. 1 and 2.

Referring now to the drawing which illustrates a preferred embodiment of my invention, i indicates a piece of fabric or material,v to be embroidered, which I shall hereinafter call an embroidery fabric, 2 indicates a piece of heatdischargeable fabric, adapted on subjection to heat to be discharged and to be brushed away, and which, in the preferred embodiment of my invention, I utilize as a protective foundation fabric or protective element. As illustrated, the embroidery fabric is superposed over the heat-dischargeable fabric with the front face of the embroidery fabric abutting the dischargeable fabric, and a faggoting-em'broidery stitch is stitched through both of said fabrics. My preferred stitch,

'3 comprises a. chain-stitch portion 3, faggoting cross-threads 3a and connecting stitch portion 3b. When this stitch is made in the superposed embroidery fabric and dischargeable fabric, the cross-threads3a extend beneath or on underside or bottom of the dischargeable fabric 2 and these faggoting embroidery threads will thus, as hereinafter described, be protected by this dischargeable fabric, which is stiff and tough, during the further operations on the fabric, d

The stitch 3 being made through the embroidery' fabricand the protecting heat-dischargeable element '2, the portion of embroidery fabric extending over the cross-threads and between the parallel edge-stitch portions 3' and 3b may be slit, as shown at 4 in Fig. 1 by a pair of scissors,

a knife or in any other suitable manner, and in this slitting operation, the heat-dischargeable protectiveelement 2, being disposed between the fabric I and thecross-threads 3a. will serve as a protectivefoundation to prevent engagement and severing of cross-threads by the severing tool, thus permitting greater speed 'in manufacturing than would otherwise be possible.

After the fabric is-slitas shown at 4 in Fig. 1,

I open up the slit, turn over the edge and initially iron or hot-press the same, and for this purpose, I utilize a novel device combining in one tool a slit-opener, edge turner and initial hot-presser.

The slit-opening portion of this tool is inserted in the slit and upon sliding the tool along through the slit on the dischargeable fabric'I turn or fold outwardly and downwardly in opposite directions the marginal edges adjacent to the slit and in the same operation I iron, or

hot-press these edges so as to cause such edges to initially retain their folded position.

As illustrated in Figs. 1, 2 and 3, inclusive, I

determined or given width equal to the width of the faggoting slits the edges of which ,are to be folded and also having a pointed insertion head portion 1 provided with an upwardly-inclined edge-raising surface I merging with a reversely-inclined wall portion 1a. Said wall portion Ea has a bevelled edge or conical surface lb serving as an edge turning or guiding portion and extending upwardly and outwardly from said neck portion and connected with pressing wing portions, as hereinabove specified. This bevel-edged or conical surface lb of the wall la preferably surrounds the semiconic pointed nose, constituting a major circumference merging at its lower ends with flat pressing wing portions beneath which the fabric margin is led to permit hot pressing, said pressing-wing portion of l'd merging with the ends of the conical surface 5b and extending outwardly from the bottom of the edge-raising portion 1. The fiat surface also preferably extends to the point 1. Suitable means is employed for supplying heat to the tool 5 and in the embodiment shown, the head 6 is provided with a shank 5' which screws into a handle 8. The handle 8 has a suitable socket 8 and contains an electric heating element of conventional form.

In using the tool 5, the pointed insertion-portion I is as above indicated, inserted in the slit, the fiat portion 7c being passed along between the edges 33b of the stitch 3 and over the protecting fabric 2 and forming a guide for the semiconic opening surface I. This portion 1' lifts and opens the marginal edges of the slit and these edges upon reaching the bevelled edge lb of the wall Ea are turned outwardly and downwardly beneath the outer wing portions Ed which merges with the flat portion To. The heating of the heating element thereupon supplies the necessary heat and pressing or ironing means to initially retain said folded portion in folded condition.

After initially folding down the marginal edges as above described, I apply on the reverse side of the fabric beneath the folded edges of the slit a conventional fastening material such as rubber, which is sprayed beneath said initially folded marginal edges by the use of conventional spraying apparatus.

The embroidered fabric is then, preferably in one operation or simultaneously, subjected to heat and pressure which not only securely fastens down the said marginal edges but also serves to discharge the protective dischargeable fabric, which, after such pressing and heating may be brushed away to leave the open faggoting channel with the cross-threads only of faggoting stitches exposed at the front side as shown in Fig. 1, while the parallel chain and connecting stitch portions 3, 3b are concealed on the reverse side by the fastened down marginal edges of the slit.

As many changes could be made in the above construction and many apparently widely dif ferent embodiments of this invention could be made without departing from the scope thereof; it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

Having described my invention, I claim:

1. A device for folding and initially pressing marginal edges of slits in fabrics, embodying, in combination, a body having adjacent to its forward end a neck portion of a predetermined width and provided with a pointed head portion extending forwardly from said neck and having an edge raising surface, said body being provided at the rear of said edge-raising surface with a pressing surface extending outwardly to opposite sides of said neck portion to provide fiat pressing wing portions, said body also having an edge-guiding surface between said edge-raising and pressing wing portions, and means for heating said body.

2. A device for folding and initially pressing marginal edges of slits in fabrics, embodying, in combination, a body having adjacent to its forward end a neck portion of a predetermined Width and provided with a pointed head portion extending forwardly from said neck and having an edge raising surface, said body being provided at the rear of said edge-raising surface with a pressing surface extending outwardly to opposite sides of said neck portion to provide fiat pressing wing portions, said body also having an edgeguiding surface between said edge-raising and pressing wing portions, said pointed head portion having beneath said edge raising surface a flattened surface continuous with the fiat wing portions, and means for heating said body.

3. A device for folding and initially pressing marginal edges of slits in fabrics, embodying, in combination, a body having a flat base-portion provided adjacent to its forward end with a neck portion of predetermined width, and a head portion extending forwardly from said neck portion and having a conical edge-raising surface, said body being provided at the rear of said edge-raising surface with an edge-pressing surface extending outwardly to opposite sides of said neck portion to provide fiat wing portions, said body also being provided at the rear of said edge-raising surface with a conical edge-turning surface extending upwardly and forwardly from said neck portion, and means for heating said body.
