` s claims. (ci. 1zss) This invention relates to the'manufacture of ladies shoe `uppers and more particularly to the application p l Applcants development This is accomplished by providing the marginal instepengaging edge of the upper with an inward inclination. The French binding is applied partly in the normal manner and at the same time the upper is deformed to round it so that the margin projects slightly inwards.

This can be accomplished by an apparatus which is adapted to feed the margin of the upper and to fold in the binding over the inner side of the marginal edge, at the same time to hammer it with a reciprocating hammer whose head is provided with a projection which co-operates with a cavity in an anvil underlying the material. This causes the deformation of the material tending it to be inclined inward.

The invention has been generally described, and the applicant will now refer to it in more detail by reference to the accompanying drawings. These drawings illustrate the application of French binding to a shoe upper in accordance with the invention. They also show, in enough detail to explain to one skilled in the art, the working parts of an apparatus adapted to carry out the method.

In the drawings:

A represents the upper of a ladies shoe, it is made up of an outer layer of leather 15 and a juxtaposed lining 17 of textile fabric. The inner marginal edge of the upper A is provided with a French binding B.

The following is a method by which this binding is applied in accordance with this invention. First, the fabric layer 17 is juxtaposed to the leather layer 15 and to the binding B, and the marginal edges of these layers and the binding B are joined together by stitching 21 as best shown in Figure 2. Then, the binding B is rolled about the edge as shown in Figure 3 and is secured to the cloth layer by adhesive 23.

In accordance with the invention, after binding tape B is in juxtaposition to the cloth layer 17 the three layers are hammered together at about the middle of the binding tape over an anvil having a special cavity so as to round the marginal edge and to give it a tendency to protrude inwards. The preferred means of doing this are illustrated in Figure 4 and the following.

The upper A is fed into an apparatus as shown in Figure 4. The marginal edge passes by an adhesive tube 41 which serves to apply the adhesive 23 to the margin of the fabric 17. Then, the binding tape B is urged inwards towards the margin of the upper by a fixed guide member 43 and by a reciprocating guide member 45 which protrudes from the slot 47 in the body of the apparatus.

Finally, the binding tape encounters a hammer 55 which reciprocates and hammers the binding tape against the underlying layersof cloth 17 and leather 15. Thus far, the procedure is conventional and the apparatus described is similar to the USMC Thermo-Cementing and Folding Machine- Model A (symbol TCF) disclosed in the literature of the United Shoe Machinery Corporation, which is hereby incorporated by reference.

In accordance with the invention, the edge of the machine over which the margin of the upper passes is provided with an anvil 61 provided with a depression or moulding cavity 63 and the hammer 55 is provided with a protuberance 57 which works in combination with the cavity 63 in the anvil 61. As the hammer 55 comes down it jams the material i.e. the edge portion of the upper, into the cavity 63 causing the forming rounding elect above described causing the upper to curl inwards. The hammer reciprocates quickly continuously striking the top of the margin of the upper as the latter is fed beneath it.

The apparatus has only been illustrated suciently for anybody skilled in the art to understand its operation. It will be understood that the various parts shown are driven by a most suitable drive through linkages connected to these parts as will be clear to one skilled in the art, since the apparatus is generally the same as that described in the USMC literature mentioned above.. The basic machinery is not a part of this invention only the modification claimed.

Further the selection of materials of the shoe is also within the skill of one in the art. Usually the upper will be made of leather but of course can be of suitable substitute material c g. synthetic leather in the nature of plastic material which will act in a manner similar to leather and so on. The lining is usually of a woven textile fabric of the type usually applied in linings, and, the binding tape is of a narrow woven fabric as usually applied for French bindings. The nature of these materials is not part of the invention and their selection will prove no problem to one skilled in the art.

I claim:

1. An apparatus for applying French binding to the margin of a shoe upper comprising means -for advancing the upper with the French binding attached, means for guiding and folding the tape Vover the edge of the upper to juxtaposition of the upper, and means for tamping the tape and portion of the upperto which it is juxtaposed including a hammer and means for reciprocating the hammer and an anvil .adapted to underlie the material being tamped, the anvil being provided withan acute depression and the hammer being provided with a correspondingly acute protuberance adapted to press the material into said depression whereby a hollow is formed at one side of the material and a convexity at the other side of the material causing it to be permanently bowed out of the flat thereby to provide an inwardly projecting multi-ply bowed edge adapted to engage the instep.

2. An apparatus for applying vFrench binding as defined in claim 1` in which means is provided for applying adhesive between the tape and the edge of the upper to which the tape is applied prior to juxtaposing the tape thereto.

3. An apparatus for applying French binding to the margin of a shoe upper having a reciprocating hammer and an anvil against which the hammer operates on the material, in which the anvil is provided with an acute rounded cavity and the hammer with a corresponding protuberance whereby the hammered material is permanently bowed out of the flat thereby to provide an inwardly projecting multi-ply bowed edge adapted to engage the instep.
