In a method of making garments by helically winding bands of material, the bands are laid out side-by-side on stock material of predetermined width and the width of the bands is selected so that the sum of the widths of the bands is equal to the width of the material. This achieves a high degree of material utilization. The sizes of garments to be produced is independent, within limits, of the widths of the band, since larger or smaller garments can be made by varying the length of the bands and controlling the helical winding. In making pants-type garments, side extension pieces of generally triangular or trapezoidal form are joined to side edges of first and second bands which are helically wound to form the legs. Such side extension pieces are laid out on the material in alternately reversed, intercalated relation and adjusted lengthwise relative to one another so that the sum of the width of pairs of side extension pieces is equal to the width of the material. In making dress-type garments, a band to be wound helically to form a body portion of the garment is shaped so as to impart shape to the garment and may be cut as a plurality of pieces which are then joined.
In a method of making a pants-type garment having two legs, a waist and a crotch, the steps of providing first and second bands of material each having first and second side edges, a lower edge and an upper edge, providing first and second side extension pieces of material each having an upper end, an outer side edge and an inner side edge having an upper portion and a lower portion inclined to said outer side edge, joining said lower portion of said inner side edge of said first side extension piece with at least an upper portion of the first side edge of said first band and joining said lower portion of said inner side edge of said second side extension piece with at least an upper portion of said first side edge of said second band so that said side extension pieces extend laterally at an angle from respective bands with the outer side edge of each side extension piece forming an angle with said first side of the respective band and with said second upper portion of the inner side edge of each side extension piece forming an extension of the upper edge of the respective band, said upper portion of the inner side edge of each side extension piece and an adjacent portion of the upper edge of the adjacent band being shaped to form the crotch of the garment, winding said first bsnd with its side extension piece helically and joining contiguous edges of edges of convolutions in a helical junction line to form a first leg of said garment, winding said second band with its side extension piece helically and joining contiguous edges of convolutions in a helical junction line to form a second leg of said garment, and joining said crotch-forming edge portions of said first band and respective side extension piece with said crotch-forming edge portions of said second band and respective side extension piece to thereby join said first and second bands and their respective side extension pieces to form said garment.
A pants-type garment comprising first and second bands of material each having first and second side edges, an upper end edge and a lower end edge, first and second side extension pieces each having an upper end, an outer side edge and an inner side edge having an upper portion and a lower portion inclined to said outer side edge, said lower portions of the inner side edges of said first and second side extension pieces being joined with at least upper portions of said first side edges of said first and second bands of material respectively, each of said bands of material with its respective side extension piece being wound helically to form a leg of said garment, means joining contiguous edges of convolutions in a helical junction line, upper end portions of said bands of material and respective side extension pieces being shaped to form a body portion of said garment, and means joining an upper portion of said first band of material and its respective side extension piece with an upper portion of said second band of material and its respective side extension piece to unite said legs and form said body portion of said garment.
In a process of making, from stock material of predetermined width, garments formed by winding at least one band of material helically and joining contiguous edges of convolutions to form said garment, the procedure of laying out a plurality of bands side-by-side on said material with the sum of the widths of said bands equal to said predetermined width of said material, whereby waste of material is avoided, cutting said bands from said material, winding resulting bands helically while controlling the helical winding of the bands to produce garments of predetermined sizes independent within limits of the width of said bands, and joining contiguous edges of convolutions to form said garments.
