ABSTRACT:
The invention is concerned with the manufacture of articles of a substantially sack-like or tubular structure and made of a material in sheet or strip form, the articles having openings with elastic bands therearound so as to resist circumferential expansion of the openings.
The invention is particularly concerned with the continuous manufacture of babies' pants, and more especially with the securing, for example by high frequency welding, of elastic bands to the waist and leg openings.
A succession of support members for the blanks is indexed to a plurality of work stations, in sequence, clamp elements being provided on the support members for holding the elastic bands in place and juxtaposing marginal portions of the material, preferably a plastics material, in a suitable manner for performing the welding operation.
