摘要： Fibrous strip material impregnated with a hardening material is wound on a hollow open-ended mandrel, continuously advanced through and cured in an in-line infrared heating apparatus and cut into separate lengths after curing. A vacuum applied to the mandrel withdraws gases and vapors from within the tube, enhancing the curing.

摘要： Multi-ply tubular members of non-circular cross-sectional shape are convolutely wound of sheet material on a mandrel of the desired non-circular shape. High bond strength is obtained by continuously pressing the sheet against the mandrel and wound plies during winding. For this purpose a presser roll of noncircular cross-sectional shape is biased against the mandrel and wound plies and rotated in timed relationship with the mandrel. The presser roll is shaped so that the combined distance from the axis of the presser roll to its surface and from the axis of the mandrel to its surface, in a plane passing through the axis of each, remains constant during winding.

摘要： A plastic piston and tubular container for dispensing semisolids, such as ice cream and the like. The piston has a flat, flexible, obturating wall; a depending peripheral skirt or flange, proportioned to guide the piston axially along the tubular container, with a flared lower edge to provide a fluidtight seal; and a central tubular hub, corrugated to provide radial flexibility, for connecting either a rodlike or tubular push device to the piston.

摘要： A tubular member with a cross section forming a three-sided figure, especially useful as a container reinforcement. The member is convolutely wound of fiber-containing sheet material and the fibers extend predominantly longitudinally of the member. When located in a corner of a box-like container or carton, the member provides substantial area contact with the container walls while occupying little volume and imparts a high degree of cubical rigidity to the container.

摘要： A helically wound tube comprised of sheetlike plies including a liner and a plurality of body plies. The liner and a first surrounding body ply are interwoven along a helical butt joint defined by adjacent edges of the surrounding body ply, and the liner forms a helical lap joint. The tube is continuously formed and an interior protective coating is concurrently applied to the tube as an airless spray of coating material comprising 100 percent solids in a liquid state, which hardens substantially on contact with the tube.
