PCT No. PCT/SE96/00117 Sec. 371 Date Sep. 24, 1997 Sec. 102(e) Date Sep. 24, 1997 PCT Filed Feb. 1, 1996 PCT Pub. No. WO96/23465 PCT Pub. Date Aug. 8, 1996A method of elastifying a non-woven or plastic jacket of a pants-type article in its unassembled hour-glass form, arranged end-to-end in a longitudinal web, includes the steps of stretching a web length of elastic net, film or elastomeric non-woven material, which is rectilinear in its unstretched state, transversely but not longitudinally at the two end portions (113) which will form the waist, stretching the length of elastic net, film or elastomeric non-woven material longitudinally but not transversely at the intermediate crotch portion (14) therebetween, whereby the net or film will naturally assume the desired hour-glass shape of the jacket to be elastified, then bonding the stretched net or film in its hour-glass shape to the jacket (5). |
