Abstract: A method of and apparatus for making a longitudinally partitioned tubular body and sealingly securing a longitudinally divided head fitment to one end of the body to form a collapsible, longitudinally partitioned tubular dispensing container assembly. A single sheet of body forming material is configured, looped, spindled, and seamed to integrally form a tubular exterior wall and a chordal partition which are sealingly secured together along two longitudinally extending lap seams in the tubular wall. An end of the tubular wall is sealingly secured to the radially outwardly facing cylindrical surface of a longitudinally extending cylindrical skirt portion of the head fitment, and the adjacent end portion of the chordal partition is sealingly secured to a longitudinally extending chordal divider portion of the head fitment.

Abstract: An improved process and equipment for seed defiberization, for example cottonseed delinting, wherein the seed is defiberized by contact with particular abrasive surfaces. In one preferred embodiment, a conventional cotton-seed delinter is equipped with an abrasive faced cylinder instead of the conventional shaft mounted ginning saws. The abrasive cylinder comprises a shaft mounted cylinder of approximate gin saw diameter which cylinder has bonded or adhered to its facial surface an open pattern of about 40 to about 80 abrasive grit particles per square inch. The abrasive grit particles, preferably tungsten carbide grit, are sized to U.S. Sieve Series numbers of about 12 to about 40. Replacement of the ginning saws with the abrasive face cylinder requires modification to the delinter gratefall rake and seed seals to adapt their shape and clearance to the comparatively flat abrasive cylinder face.
