The specific embodiment

The present invention is described in detail below in conjunction with drawings and Examples:

Shoe-pad making method first preferred embodiment of the present invention comprises the following steps:

Step 1: as shown in Figure 1, prepare a foaming elasticity base pad 10 and a press unit 100 with predetermined thickness.The foaming elasticity base pad 10 of present embodiment is monochromatic ethene-vinyl acetate copolymer (EVA) or thermoplastic elastomer (TPE), and applied thermoplastic elastomer is TPU (a thermoplasticity polyamine fat elastomer), TPR (thermoplastic rubber), TPO (polyolefin elastomer) ... etc., and this foaming elasticity base pad 10 has two and is opposing lateral surface 101, the press unit 100 of present embodiment has first rolled-up stock 110 and second rolled-up stock 120 that is oppositely arranged and is the running roller shape with this first rolled-up stock 110 that are the running roller shape, this first rolled-up stock 110 has most and protrudes and be laid in first protuberance 111 on the outer peripheral face towards this second rolled-up stock 120, this second rolled-up stock 120 have most with the stagger setting and be laid in second protuberance 121 on the outer peripheral face of described first protuberance 111.

Step 2: as shown in Figure 2, utilize 100 pairs of these foaming elasticity base pad 10 crampings of this press unit, and first and second protuberance 111,121 of this first and second rolled-up stock 110,120 is pushed by lateral surface 101 and towards these foaming elasticity base pad 10 inside respectively, and at the most individual positions 111 ' of pushing of lateral surface 101 each formation.

Step 3: more as shown in Figures 1 and 2, utilize 200 pairs of crampings of a cutter to dissect, and make this foaming elasticity base pad 10 form two lamellar bodies 11 in the foaming elasticity base pad 10 of 110,120 of this first and second rolled-up stocks.

Step 4: make described lamellar body 11 in this press unit 100, shift out, that is to say, make the press power that this press unit 100 discharges lamellar body 11, and as shown in Figure 3, described lamellar body 11 respectively has the opposing medial surface 102 of a lateral surface 101 and and this lateral surface 101, originally the extruding position 111 ' that was formed at lateral surface 101 is replied because extruding force allays and is plane, relatively, on medial surface 102, because the extruding force at extruding position 111 ' disappears and forms most depressed parts 112 ' in the corresponding position, the periphery of described depressed part 112 ' then relatively forms most juts 113 '.

Step 5: as shown in Figure 4, at fit a respectively cloth cover 20 and respectively form semi-finished product 30 of the lateral surface 101 of described lamellar body 11.

Step 6: described semi-finished product 30 are cut, locate to carry out punching at the described depressed part 112 ' of correspondence simultaneously.

Utilize above-mentioned steps, make most shoe-pads 30 ', described shoe-pad 30 ' respectively has the opposing air-vent 32 ' (see figure 5)s that bottom surface 31 ' and most connect layer of cloth 20 ' and bottom surface 31 ', this bottom surface 31 ' constitute wavy by depressed part 112 ' and jut 113 ' of being provided with of one deck layer of cloth 20 ', and this layer of cloth 20 '.

And this shoe-pad 30 ' is because bottom surface 31 ' is wavy, so have three-dimensional appearance and modeling, and also, be formed with the permission deformation space and the position is set, and make shoe-pad 30 ' have preferable support elastic at depressed part 112 ' because this bottom surface 31 ' is wavy.

Shoe-pad making method second embodiment of the present invention comprises the following steps:

Step 1 ': as shown in Figure 6, prepare a foaming elasticity base pad 40 and a press unit 100 with predetermined thickness.The foaming elasticity base pad 40 of present embodiment is double-colored ethene-vinyl acetate copolymer (EVA) or thermoplastic elastomer (TPE), this foaming elasticity base pad 40 has two base materials 41 and the intermediate wood 42 between 41 of described base materials, the color of described base material 41 is identical and respectively have a lateral surface 411, and the color of this intermediate wood 42 is different from described base material 41.This press unit 100 also has first rolled-up stock 110 and second rolled-up stock 120 that is oppositely arranged and is the running roller shape with this first rolled-up stock 110 that are the running roller shape, this first rolled-up stock 110 has most and protrudes and be laid in first protuberance 111 on the outer peripheral face towards this second rolled-up stock 120, this second rolled-up stock 120 have most with the stagger setting and be laid in second protuberance 121 on the outer peripheral face of first protuberance 111.

Step 2 ': as shown in Figure 7, utilize 100 pairs of these foaming elasticity base pad 40 crampings of this press unit, and first and second protuberance 111,121 that makes this first and second rolled-up stock 110,120 is respectively by described lateral surface 411 and towards these intermediate wood 42 inner extruding, and at most extruding of lateral surface 411 each formation positions 411 ', and this intermediate wood 42 also can be wavy by first and second protuberance 111,121 extruding.

Step 3 ': Figure 6 and Figure 7 for another example, utilize 200 pairs of crampings of a cutter to dissect, and make this foaming elasticity base pad 40 form two lamellar bodies 400 in the foaming elasticity base pad 40 of 110,120 of this first and second rolled-up stocks.

Step 4 ': make described lamellar body 400 in this press unit 100, shift out, that is to say, the press power that this press unit 100 is discharged lamellar body 400, and as shown in Figure 8, described lamellar body 400 respectively has the opposing medial surface 412 of a lateral surface 411 and and this lateral surface 411, originally the extruding position 411 ' that was formed at lateral surface 411 is replied because extruding force allays and is plane, relatively, on medial surface 412,, the extruding force at extruding position 411 ' forms most depressed parts 412 ' because disappearing in the corresponding position, the periphery of depressed part 412 ' then relatively forms most juts 413 ', and the surface of described jut 413 ' can utilize this intermediate wood 42 to be cut open and form double-colored.

Step 5 ': as shown in Figure 9, at fit respectively one deck cloth cover 200 and respectively form semi-finished product 300 of the lateral surface 411 of lamellar body 400.

Step 6: described semi-finished product 300 are cut, locate to carry out punching at corresponding depressed part 412 ' simultaneously.

Utilize above-mentioned steps, make most shoe-pads 300 ', described shoe-pad 300 ' respectively has the opposing air-vent 320 ' (see figure 10)s that bottom surface 310 ' and most connect layer of cloth 200 ' and bottom surface 310 ', this bottom surface 310 ' constitute wavy by depressed part 412 ' and jut 413 ' of being provided with of one deck layer of cloth 200 ', and this layer of cloth 200 '.

Whereby, this bottom surface 310 ' also utilizes the setting of part intermediate wood 42 and forms the three-dimensional contouring of double-colored staggered color matching.
