ABSTRACT:
Apparatus for providing resiliently compressible articles, which by being compressed have been lended a considerably reduced volume, with a casing formed of heat sealable pliable sheet material preventing the articles from regaining their original volume. The articles are first precompressed to a volume which is smaller than said reduced volume. The precompressed articles are thereafter introduced into a tube which is formed of a lengthy web of pliable sheet material by heat sealing overlapping longitudinal margin portions of the web so as to unite them. The articles introduced into the tube are prevented from expanding to said reduced volume, in which they fill out the tube, until the heat sealing seam of the tube has attained sufficient strength. The tube can be closed between the introduced articles by transverse heat sealing seams.
