Abstract
A rewind shell having particular utility in the textile industry is comprised of radially extending webs arranged in an angularly displaced array symmetrically about a common longitudinal axis of the rewind shell, the webs each having flanges at their radially outer edges curved about a radius of the common longitudinal axis, the webs and flanges being formed integrally as a unitary metal extrusion. End caps are provided at each end of the rewind shell having support segments extending into the interior of the shell for them to dimensionally stabilize the shell.
Claims4
A rewind shell assembly, of particular utility in wet processing in the textile industries, comprised of:
- a unitary extrusion of an extrudable metal providing, in transverse cross-section, radially extending webs extending in angularly spaced relation radially of a central longitudinal axis of said extrusion, and each interconnected with the other at a radially inner longitudinal edge of each said web;
- a laterally extending flange integral with each said web at a radially outer edge of each said web, each flange being curved about a radius of said central longitudinal axis;
- and,
- a drive member separate from said rewind shell and inserted into each axial end of said unitary extrusion, each said drive member including a radially extending flange portion, and, driving dogs formed integrally with said radially extending flange portion and respectively extending axially into said unitary extrusion, said respective driving dogs being of substantially greater axial length than the wall thickness of said respective webs and each having axially extending walls complimentary to an adjacent pair of said webs and their associated said flanges for each said driving dog to internally engage a said adjacent pair of said webs and said associated flanges in supporting and driving relationship therewith;
- said driving dogs being operative to prevent movement of said webs from their radially extending orientation and being operative to prevent collapsing movement of said laterally extending flanges in directions radially inwardly of said unitary extrusion.
