Shoe Making Method with One-side Cementing by Applying Powder Adhesive

Abstract

A shoe making method includes adhesion of an outsole and a midsole, and adhesion of a sole and a vamp. When the outsole and the midsole are attached, an upper adhesion surface of the outsole is processed by coating absorbent and by spraying powder adhesive, while a lower adhesion surface of the midsole is processed by spraying two-in-one primer, to achieve a one-side cementing. When the sole and the vamp are attached, an upper surface of the sole is processed by coating absorbent and by spraying powder adhesive, while a lower adhesion surface of the vamp is processed by spraying two-in-one primer, to achieve a one-side cementing. The powder adhesive is uncharged powder adhesive which is directly sprayed by a machine, without needing static attachment. The two-in-one primer is made of reinforcer and glue.

1 . A shoe making method comprising:
 adhesion of an outsole and a midsole, and adhesion of a sole and a vamp;   (a) the adhesion of an outsole and a midsole including:   (1) washing and buffing: washing and baking the outsole and the midsole or directly buffing an adhesion area of the outsole and the midsole;   (2) surface modifying: wiping a modification agent on a surface of the outsole and the midsole;   (3) coating and spraying: coating an absorbent and spraying a powder adhesive on the outsole, and spraying a two-in-one primer on the midsole;   (4) adhering: attaching the midsole and the outsole so that the midsole and the outsole are adhered to form a sole;   (b) the adhesion of a sole and a vamp including:   (b1) a step of processing the sole including:   (1) washing and buffing: the upper surface of the sole is processed by washing and baking or buffing;   (2) surface modifying: the upper surface of the sole is processed by wiping a modification agent and baking; and   (3) coating and spraying: the upper surface of the sole is processed by coating absorbent, spraying powder adhesive and baking;   (b2) a step of processing the vamp including:   (1) vamp treatment: the vamp is processed by surface buffing or surface modifying;   (2) brushing: the vamp is processed by brushing two-in-one primer and baking: and   (3) adhering: the vamp and the sole are attached;   the improvement comprising:   when the outsole and the midsole are attached, an upper adhesion surface of the outsole is processed by coating absorbent and by spraying powder adhesive, while a lower adhesion surface of the midsole is processed by spraying two-in-one primer, to achieve a one-side cementing; and   when the sole and the vamp are attached, an upper surface of the sole is processed by coating absorbent and by spraying powder adhesive, while a lower adhesion surface of the vamp is processed by spraying two-in-one primer, to achieve a one-side cementing.   
     
     
         2 . The shoe making method of  claim 1 , wherein:
 when the outsole and the midsole are attached, the upper adhesion surface of the outsole is processed by spraying two-in-one primer, while the lower adhesion surface of the midsole is processed by coating absorbent and by spraying powder adhesive, to achieve a one-side cementing; and   when the sole and the vamp are attached, the upper surface of the sole is processed by spraying two-in-one primer, while the lower adhesion surface of the vamp is processed by coating absorbent and by spraying powder adhesive, to achieve a one-side cementing.   
     
     
         3 . The shoe making method of  claim 1 , wherein the powder adhesive is uncharged powder adhesive which is directly sprayed by a machine, without needing static attachment. 
     
     
         4 . The shoe making method of  claim 1 , wherein the two-in-one primer is made of reinforcer and glue.
