PROCEDIMIENTO PARA LA FABRICACION DE PRENDAS DE UN SOLO USO

摘要

Adhesive is intermittently coated onto an elastic strip 4 which then passes over a grooved pulley 9 mounted on a slide or carriage 10 able to move intermittently on a slideway 11. A continuous flexible sheet consisting of a moisture-impermeable heat-sealable material is unreeled over the periphery of a rotary drum 3. The point of contact between the elastic strip 4, and the travelling impermeable sheet 2 is moved periodically in a direction transverse to the direction of travel of the sheet 2. This results in laying, along a curved path 4a of, a stretched elastic adhered to sheet 2. It is thus possible to make diaper units comprising crotch elastics edging the curvilinear profile of the leg openings or cut-outs.
