Abstract: 1,250,788. Making trousers. C. R. PIERRON. 5 Nov., 1968 [6 Nov., 1967; 20 Feb., 1968; 15 Oct., 1968], No. 52318/68. Heading A3V. A method of manufacturing trousers and like garments comprises the steps of: superposing two layers 201, 202 of supple material, bringing the two layers together, as in stage IV, fig. 25a arid assembling them along the back medial seat line 211 and the fork line 214; forming two flattened tubular legs by superposing two additional layers of material, as in stage IX, fig. 25b, and assembling the layers into two pairs along at least the back fold line 226 and severing the two pairs of trousers formed along the line 226. In stage I of a production line for carrying out the method, two parallel rolls 203, 204 of material feed the production line with two webs 201, 202; transverse spaced edging 206, which are preferably of adhesive strip, is attached to each web on the sides of the webs which face one another. In stage II, fly fasteners 207, 207', such as an unstickable glue, buttons, or sliding fasteners are laid in two parallel rows across the edgings 206. In stage III, glue is laid along seat lines 210 on at least one of the webs. In stage IV, the two webs are brought together, and stuck along the seat lines 210 by the previously applied glue. In stage V, the two webs are cut along line 211, 211' and 212, 212', and along hip pocket openings 213, 213'. The webs are also perforated along lines 214, 214', so that the material bounded by lines 211, 214, 211' and 214' may eventually be used as an inner part of the hip pockets. In stage VI, longitudinal fly fastening glue lines 215, 216 and 215', 216' are laid on the upper face of web 201 and the lower face of web 202. In stage VII, the flaps formed in stage V by cuts 211, 212, and 211', 212' are folded outwardly and stuck against the webs by the glue applied in stage VI. In stage VIII, glue is applied to the lower web on its lower side along a marginal line 219a, an undulated medial line 220a representing the back fold of the trousers and along the outlines of the inner parts of the pockets defined by perforations in stage V. Similar gluing is carried out on the upper face of web 201. In stage IX, the two webs are folded outwardly so that the edges 223a, 224a of the lower web are joined together along a line 225a forming a tube, and similarly with the upper web. At the same time the tubes are joined along the undulated glue line 220 so that two pairs of trousers are formed. In stage X the trousers are cut along the undulated join 226 in the middle of glued area 220, and also along the middle of the transverse edging 206. Belt passing holes 227 are also made in the parts of edging 206 which are at the top of each pair of trousers. In stage XI the trousers are piled up. The length and waist of the trousers may be varied by altering the separation of edgings 206 and the web width respectively. Alternative securing methods such as stitching, sewing, or hot welding may be used in place of gluing. In another embodiment, Figs. 45a, b (not shown), trousers are made with their length transverse to the web length, and four webs are used to replace the folding into tubes in stage IX above. The position of the seams in the trousers legs may be varied relative to the front and back folds to give any. of the configurations in figs. 11-22 (not shown). A mechanical layout suitable for the embodiment of figs. 45a, b is also given, figs. 43a, b (not shown).
