Method of manufacturing jackets and like garments

Abstract

A method of continuously manufacturing jackets, in series in an assembly line, from a web, consisting in making pairs of right and left sleeves and laying them flat in a longitudinal row on said web, superposing thereon over said sleeves two bands laterally secured to the edges of said web, respectively, and covering each a different row of sleeves, to form the left and right front sides of the jackets, assembling said bands and web to the outer periphery of the sleeve arm-opening lines and severing the finished jackets.

What is claimed is: 
     
       1. A method of manufacturing jackets and garments and like wearing apparel with sleeves of various lengths from any kind of supple sheet material, wherein the improvement consists in an industrial mass production by means of a substantially continuous assembly line formed from at least one indefinite initial web of material the width of which is at least equal to the maximum width of a jacket back and consisting in successively making respectively right and left pairs of sleeves and placing them in a flat-spread condition in at least two longitudinal rows of respectively right and left sleeves against and all along the said web in such a manner that the two sleeves of each pair are substantially symmetrical with respect to a longitudinal axis, longitudinally superposing on the said web over the said sleeves at least two elongated layers of materials laterally adjoined to the said web respectively along a longitudinal line extending at least close to one edge of the web and freely transversely juxtaposed so as to each cover a different row of sleeves and intended to form respectively the left and right front sides of the jackets, assembling the two layers and the said web respectively to the outer periphery of the upper end of the sleeves along corresponding arm-opening lines so as to form a series or sequence of jackets whose own longitudinal direction corresponds to the longitudinal direction of the assembly line, and separating or severing the finished individual jackets of the assembly line by cutting along at least approximately transverse jacket-bottom, neck-opening and shoulder lines, the jackets obtained at the exit of the assembly line being in a state folded inside out on the sleeves.
