convolute

* General-deburring wheels--hard density, fine-grit convolute wheels that provide an excellent value for edge deburring performance.

The cylindrical worm having the flanks as helical surfaces of a convolute helicoid of the second specie has the property that in the normal section on the reference medium helix of the tooth or of the tooth space.

General design of convolute shapes is dictated by the requirements for flexibility, bellows stiffness, diameters, extension and collapse limits.

Single-wrap convolute canisters are made in the traditional round shape (Ultrakan[R]) and also can be custom-formed (Vektor[TM]) packages that offer the billboard facings of a rectangular box with the attractive visual attributes of round canisters.

In blow molding of convolutes, the parison should be sized as close as possible to the convolute root diameter.

The closure system eliminates the common problem of sharp edges on slit convolutes that can snag, cut wires or injure assembly workers.

My favorite work in this miniretrospective of mostly late sculpture was a relatively early piece, Convolute, 1944.

Topics include injection molding, grips, shutoff design, extrusion, blow molding, seals, tubes, ducts and bellows, and convolutes. The TPV document is kept updated.
