Abstract: An apparatus and method are disclosed for a continuous compressing operation involving receiving pliable articles, compressing them along a single axis, and releasing them once compresssed. The apparatus and method each involve the use of a pair of disks arranged in a V-shaped configuration, with their opposing surfaces contoured to form opposing recesses which, together with a flexible barrier spanning the space between the disks, define a pocket opening toward the rims of the disks for receiving the article and retaining it during compression. The disks are rotated while maintaining the V shape, thereby causing the pocket and hence the retained article to become compressed. Once the narrowest point of the V is passed, the compressed article is released by gravitational force.

Abstract: An overlay molding press which includes a pair of oppositely disposed jaw members.

Abstract: A vertical format corrugator or the like tube producing apparatus has two sets of independent mold sections that circulate on respective paths. The mold sections co-operate to define a travelling mold cavity into which a thermoplastic tube may be extruded to be molded. Fixed tracks extend along the forward and return runs of the mold section paths and are engaged by track followers on the mold sections. The track followers support and guide the mold section, thus enabling the elimination of chains linking the mold sections. In preferred embodiments, transfer mechanisms are provided at the ends of the runs to transfer the mold sections individually from one run to the next. The mold sections may include removable mold blocks, means for automatically changing the configuration of the mold cavity and a system for internal cooling of the mold sections.
