ABSTRACT:
A method and apparatus for automating the production of pants from at least four workpieces, whereby construction is initiated by aligning the outseam edges of one front workpiece with one back workpiece, and joining these edges for forming a composite workpiece, the operation is then repeated for obtaining a second composite workpiece; the composite workpieces are folded open and like edges are aligned together; either one of the aligned front or back rises are joined; the unjoined rise may be folded open and a waistband joined to the waist edge portion; the material is folded back to place the unjoined rise edges in alignment, and the other rise is joined; one leg is folded back to place the unjoined rise edges in alignment, and the other rise is joined; one leg is folded over or under the waist for leg bottom finishings; the material is next folded about the central longitudinal axis of the pants with the legs spread away from one another; inseam edges for each pant leg are aligned; and the inseams are joined for completing the primary assembly or construction of the pants. Apparatus for carrying out the method of the invention includes a plurality of work modules including material manipulating and orienting tooling and material joining machines.
