Description
- 1. Field of the Invention
- The present invention relates generally to shoes, and more particularly to a method of making insoles, in which no hot-press molding is applied in the method.
- 2. Description of the Related Art
- Conventional insoles are classified into flat insoles and molded insoles. The flat insole is made from a foamed substrate, which is made of Polyurethane (PU) or Ethylene Vinyl Acetate (EVA) etc., put on a mold and cut by a cutter to have a shape of the insole. The substrate after cut still keeps its original character to provide a well damping capacity. As shown in
FIG. 10 , an aspect of ashoe 10 is decided by the aspect of last, such that an interior sidewall of alining 11 and a top of a sole 12 have specific curvatures, such that aflat insole 20 with aflat periphery 21 cannot be fitted to thecurved lining 11 and sole 12. As shown inFIG. 11 , when a foot (shown as the dot line) is on theinsole 20, the insole cannot provide the foot a complete support. In addition, as shown inFIG. 12 andFIG. 13 , if theinsole 20′ is wider than the sole 12 of theshoe 10′ (referring toFIG. 13 ), the insole is warped at a margin thereof to compress the foot that makes people feel not so well. In addition, the flat insole cannot fit the profile of foot as well. - The molded insole is made of a thicker substrate being hot pressed into a predetermined sharp. The molded insole has a predetermined profile at a top thereof to fit foot and a curved periphery to fit shoe, such that the molded insole is considered to support foot well. The molded insole, which is processed by hot press, is harder than the flat insole, such that people feels not so well with the molded insole. In addition, if the curvature of the molded not fitting the shoe, it provides foot more compression than the flat insole.
- The aspect of insole is decided by the cutter and the mold, in other words, the insoles with various sizes are cut by various cutters and molds respectively. Furthermore, it has to prepare a plurality of hot-press molds of various sizes for the insoles also. Therefore, it cost much for the manufacturers to have the cutters and the molds. To reduce cost on the cutters and the molds, manufacturers usually select the insoles closing to the aspect of shoes rather than design the insoles to fit the shoes. As a result, the molded insoles are not fitted to shoes as expectation.
- The advantages and the disadvantages of the conventional flat insole and the molded insole are described hereunder:
- The advantages of the flat insole: lower cost in fabrication, softer and well elasticity (it is because the substrate keeps the original character still) and lighter in weight.
- The disadvantages of the flat insole: poor support to the arch of foot and cannot put in a shoe with a protrusion on the sole associated with the foot arch.
- The advantage of the molded insole: well support to foot and can put in a shoe with a protrusion on the sole associated with the foot arch.
- The disadvantages of the molded insole: higher cost in fabrication (because the cutters and molds and the raw material needed more than the flat insole) and harder, heavier in weight and poor elasticity.
- The primary objective of the present invention is to provide a method of making insoles, which the insoles can be applied to any shoe and keeps the original character of the foamed substrate, as well as the insole provide foot a well support than the conventional flat insole. The insole of the present invention is not processed by the hot press to lower the cost thereof and reduce the waste of raw material.
- According to the objective of the present invention, a method of making insoles comprises the steps of: a) Preparing a substrate having a foamed main member. b) Cutting the substrate to have a plurality of plates, wherein each of the plates has a top and a bottom at opposite sides and a periphery between the top and the bottom thereof. c) Removing parts of the peripheries of the plates to have a taper periphery respectively.

FIG. 1 toFIG. 8 , a method of making insoles comprises the steps of: - As shown in
FIG. 1 , to have amain member 31, which is made of foamed Polyurethane (PU), anonwoven fabric layer 32 and abottom layer 33. The bottom layer is a meshed film with a friction coefficient greater than that of themain member 31. - As shown in
FIG. 2 , to attach thefabric layer 32 on a top of themain member 31 and thebottom layer 33 on a bottom of themain member 31 to have asubstrate 30. - As shown in
FIG. 3 andFIG. 4 , to cut thesubstrate 30 to have a plurality ofplates 40. A conventional cutter and mold are providing for the cutting procedure. Each of theplates 40 has atop 41, abottom 42 and aperiphery 43 between thetop 41 and thebottom 42. Theplates 40 have anarch portion 44 at a middle section thereof respectively. - As shown in
FIG. 5 andFIG. 6 , to cut theperipheries 43 of theplates 40 respectively, and theperipheries 43 are cut more at thearch portions 44 respectively (referring toFIG. 6 ). As a result, each of theplates 40 has ataper periphery 43, and a width of thebottom 43 is narrower than that of thetop 41, and theplates 40 now areinsoles 50. Furthermore, a width of thetaper periphery 43 at thearch portion 44 is greater than that of at the rest. - As shown in
FIG. 7 , while theinsole 50 of the present invention is put in ashoe 60 having aprotrusion 61 associated with the foot arch, thetaper periphery 43 of theinsole 50 fit an interior sidewall of alining 62. Thetaper periphery 43 at thearch portion 44 is wider than at the rest to fit theprotrusion 61 of theshoe 60. - As shown in
FIG. 8 , when a person wears theshoe 60 and steps his/her foot on theinsole 50 of the present invention, thetaper periphery 43 thereof has a complete structure and a well strength, such that theinsole 50 of the present invention has a complete attachment on theinterior sidewall 62 of theshoe 60, and there is less space between theinsole 50 and theshoe 60 to provide the foot a well support and to locate the foot at a correct position. In addition, theinsole 50 of the present invention is not processed by hot press, such that it has a well damping capacity and softness. In conclusion, theinsole 50 of the present invention has the advantages of both of the flat insole and the molded insole but the disadvantages. - It has to be mentioned that the taper periphery of the insole should have various profiles to meet the actual requirement. The manufacturers should have the unique design to cut the periphery to meet the very shoes. The fabric layer is provided to prevent the main member from damage when the person steps on the insole and walks, and the bottom layer is provided to give a greater friction between the shoe and the insole, therefore, there is less movement of the insole in the shoe when walking. The process of cutting the periphery should apply scrubbing or grinding also. In conclusion, the main scope of the present invention is to manufacture an insole with a taper periphery, and the taper periphery is not formed by hot press, such that the profile of the taper periphery, the arch portion, which kind of the material made of the insole and with or without the fabric layer and the bottom layer are not the restrictions of the present invention.
- As shown in
FIG. 9 , a method of makinginsoles 70 of the second preferred embodiment of the present invention comprises the steps of: preparing asubstrate 71, cutting thesubstrate 71 by laser to have a plurality of theinsoles 70. In the laser cutting process, ataper periphery 72 is formed directly on theinsole 70, in which a width of a top 73 of theinsole 70 is greater than that of a bottom 74.
