[0016] The technical scheme in the embodiment of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiment is only a part of the implementation of the utility model, and not all the implementation, based on the embodiment of the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0017] As Figure 1 And Figure 2 The utility model provides a kind of folding edge mould for vamp fabric, including bottom plate 1, the bottom plate 1 is equipped with the work area 3 for placing fabric 41, one side of the fabric 41 is folding edge portion 42, the periphery of the work area 3 is equipped with limiting step 2, the limiting step 2 is fixedly connected with bottom plate 1, the height of limiting step 2 is h, the thickness of fabric 41 is t1, the thickness of folding edge portion 42 is t2, h=(t1+t2)*a, a ∈ (1.1,1.2).

[0018] The utility model provides a kind of folding edge mould for vamp fabric, select the folding edge mould with the same work area as the shape of fabric, fabric is placed in the work area of folding edge mould, so that folding edge portion falls outside the outer contour of work area, glue is brushed on folding edge portion surface, folding edge portion outside the outer contour of work area is folded to the inside of the outer contour of work area, and it is pressed and shaped, folding edge strength is high, shape is full, beautiful, folding edge tool structure is simple, convenient to use.

[0019] As Figure 1As shown, one side of the limiting step 2 is provided with a scale line, for shoes and boots that need to paste the braid, the scale line can be used to position the braid, according to the scale line drawn on the fabric 41 paste braid, braid for inserting shoelace.

[0020] The bottom plate 1 and the limiting step 2 are made of plastic material respectively, in the embodiment, the leather fabric at the boot cylinder is folded, the limiting step 2 is arranged on the side of the working area 3, so that the working area 3 is a groove relative to the limiting step 2, in actual use, the folding die is also suitable for other materials of the vamp material, the material of the vamp material is not limited, such as Figure 3 As shown, when the edge of the fabric is folded, the fabric is placed in the working area, the edge is directly folded, and a gap is formed between the fabric and the edge, which can form a full arc and an attractive appearance.

[0021] The utility model discloses the drawing only provides the folding die with a shape working area 3, in actual use, the folding die with the corresponding shape working area 3 of the fabric 41 shape can be made, as long as the fabric 41 shape and the shape of working area 3 are same, the fabric 41 can be just laid flat in the working area 3, so that the fabric can be limited by the limiting step 2 on the side of the working area 3, prevent the movement of position, the fabric 41 can be folded quickly by the folding die, and the shape after folding is full and attractive, since not completely overlap, but produce full arc, do not produce creases, so that the strength after folding is high.

[0022] The fabric 41 is placed in the working area 3 according to Figure 2 The folding is completed, as shown by the red line Figure 2 The connecting part of the folding part 42 and the fabric 41 forms a certain arc, that is to say, there is a small gap between the folding part 42 and the fabric 41 at the connecting part, so that the folding part 42 is not completely overlapped, and no creases are produced, the shape after folding is more full, and the appearance is attractive.

[0023] The specific working process of the utility model is as follows:

[0024] The embodiment is described by taking the leather material folded edge of the two sides of the boot shaft shoe belt as an example, the width of the leather material is 25mm-30mm, the thickness is 0.3mm-0.5mm, the leather material is skived on one side to form the folded edge part 42, the width of the folded edge part 42 is 10mm-11mm, the thickness is 0.4-0.6 of the thickness of the unskived leather material, the unskived is the material 41, the skived is the folded edge part 42, the skiving refers to thinning the leather material, that is, the thickness t2 of the folded edge part 42 is 0.4-0.6 of the thickness t1 of the material 41, if the material is not skived, the thickness t2 is equal to the thickness t1, and the limiting step 2 has the following relationship with the vamp material, h=(t1+t2)*a, a∈(1.1, 1.2), so that a gap is formed between the material 41 and the folded edge part 42 after folding, and the shape is full.

[0025] Before use, select the folded edge mold with the same shape as the material 41 of the working area 3, so that the material 41 can be placed in the working area 3 of the folded edge mold, after selecting the folded edge mold, the material 41 is laid in the working area 3, and the limiting step 2 on the side of the working area 3 is used to limit the material 41 in the working area 3, to prevent the material 41 from moving and affecting the folding effect;

[0026] After the material 41 is placed, at this time, the folded edge part 42 on one side of the material 41 is located outside the outer contour of the working area 3, glue is brushed on the upper surface of the folded edge part 42, the working staff folds the folded edge part 42 outside the outer contour of the working area 3 by hand or a flat plate, so that the folded edge part 42 is folded into the outer contour of the working area 3, and the folded folded edge part 42 is pressed, then, the pressure device is pressed, which can be hammered 2-4 times or directly pressed by a cylinder, so that the folded edge part 42 can be pasted on the material 41 after folding and shaping, the action is continued until all the folded edge parts 42 along one side of the working area 3 are folded and shaped, the material 41 with the folded edge is taken out, and the folding is finished.

[0027] The technical means disclosed in the utility model scheme is not limited to the technical means disclosed in the above-mentioned embodiments, and also includes the technical scheme composed of any combination of the above technical features. It should be noted that, for ordinary skilled persons in the art, without departing from the principle of the utility model, some improvements and decorations can be made, which are also considered as the protection range of the utility model.
