RU2205578C2 - Method for manufacture of warmed boots - Google Patents

Abstract

FIELD: shoe industry. SUBSTANCE: boot has felt top part or part adhering to shinbone and provided with rear joint. Top part or shinbone part may be extended. Boot is supplemented with circular layer, with beveled cut extending from said layer. Method involves cutting single top part from roll material; applying form stability improving solution to zones of top part corresponding to boot top, tip and heel parts; providing preliminary extension of front line of top part or shinbone part, with following forming and fixation by means of vibrocassette configured to conform boot profile; cutting layer from rolled felt and connecting rear edges to form rear joint; making beveled cut extending from face so that layer is flush with inner side of top part; applying solution to zones corresponding to tip and heel parts for further forming on press and fixation; connecting felt layer to top part; securing said parts and attaching them to sole. EFFECT: improved quality, provision for obtaining comfortable and warm boots and improved appearance. 6 dwg

Description

 The invention relates to the shoe industry and can be used in the manufacture of, for example, insulated boots with felt tops.

 A known method of assembling shoes containing a flexible upper and a rigid sole, between which insert an intermediate part made by molding a flexible material. The method involves at least two stages, in the first of which a part of the sole is closed with an intermediate part, as a result of which a connecting surface is obtained, in the second stage, pressure is applied to the outer surface of the shoe, which presses the part against the sole in the area of the connecting surface [1].

 A known method of manufacturing insulated shoes, according to which on the sole of a felt stocking, previously worn on the block, at a distance of 14-16 mm from the edge an oblique incision is made for 1/2 the thickness of the stocking. Then, this incision is lifted and impregnated with various adhesives. A welt is sewn to the felt lip processed in such a way [2].

 The closest in technical essence and the achieved result is a method of manufacturing insulated boots with felt top, consisting in cutting a workpiece from a rolled material and connecting it to each other in the form of a stocking with the formation of a bottom assembly, the boot workpiece is cut from one part in zones corresponding to the front line the bootleg, toe and heel of the boot, apply a solution to increase the dimensional stability, pre-stretch the front line of the bootleg bootstrap with its subsequent molding and fixing by means of a vibrocassette. Then the workpiece is connected to each other in the form of a stocking and attach the bottom node, consisting of a molded cup-shaped sole [3].

 The disadvantage of this method is that the felt is a sufficiently rigid material and it is difficult to form a boot or shoe in the shape of a foot so that it is aesthetically receptive.

 The invention solves the problem of combining two materials in a product - felt and felt in order to increase aesthetic and heat-shielding properties.

 The goal is achieved by the fact that in the method of manufacturing insulated shoes, which consists in cutting a workpiece from rolled material, and the workpiece is cut out from one part, in areas corresponding to the front line of the shaft or berets, the toe and heel parts of the shoe, a solution is applied to increase the dimensional stability, after which pre-stretching the front line of the shaft or sides of the workpiece and its subsequent molding and fixing by means of a vibro cassette having a profile corresponding to the profile of the boot, according to the invention The blank is cut out of the roll felt, and the liner is made from the roll felt, made as a circular squeegee or sub-dress, each connected to each other by the rear seam, from the edge they make an oblique cut so that the lining or the sub-shell is flush with the inner side of the work, in the areas corresponding to to the heel and toe parts, a solution is applied for subsequent molding on the press and fixing, then they are connected to the felt blank from the felt, fastened and secured to the sole.

 A method of manufacturing insulated shoes is shown in figures 1-6.

 FIG. 1 - zone application form-resistant material; figure 2 is a workpiece assembled at the rear seam and fixed on a vibro cassette; figure 3 - blank top with a lining or in a row, bottom view; figure 4 - lining of felt, made as a circular vamp; figure 5 - section aa in figure 4; 6 is a subcontract.

 A method of manufacturing insulated shoes is painted on the example of the manufacture of women's boots.

 They make boots or boots from felt felt 1 with a thickness of 2.0-2.5 mm. The workpiece is cut from one part, taking into account the change in the angle of inclination of the front line of the shaft and its forthcoming molding. The angle of inclination is performed individually on the foot. From the felt felt 2 of a thickness of 2 mm, a lining is made that is made as a circular vamp 3 [4] (Fig. 4) or a sub-dressing 4 [5], and an oblique cut is made from the face (Fig. 5). On the inner side of the lining 3 or contract 4 and the workpiece top 1 in the zones of the forefoot and heel, and on the workpiece top also on the front line of the shaft, a resin-based chlorinated polyvinylchloride adhesive composition is applied (Fig. 5). The top blank is preformed on the front line of the shaft and stitched along the back seam. After grinding the workpiece at the rear seam, moistening, insert a vibro cassette with teeth in the workpiece to fix it, expose the workpiece to a hood, at which the material is redistributed during vibration and fixed in the extreme extended position (figure 2). Subcontract or lining is subjected to wet-heat treatment, assembled and finally molded on the block. After that, the top blank is also subjected to wet-heat treatment, stretched to a sub-board or lining, on which glue based on chloroprene latexes is preliminarily applied, assembled in the form of a stocking, and finally molded. The lining or sub-trim and the blank of the top are sewn along the track (Fig. 3). Then the sole is glued to the top. A thin felt insole is inserted into the shoes.
