A tire mold equipped with features for protecting the tread mold segments from damage is described. One or more impact absorbers are positioned between tread mold segments and operate to preclude contact between the shoulders of the tread mold segments when such are biased back into their original position as a tire is removed from the tire mold. By precluding such contact, the tread mold segments are protected from damage that can affect the appearance of the cured tire.

A generally cylindrical core for winding a web of sheetlike material has portions with a lesser diameter than other portions such that otherwise baggy areas of the web overlie the lesser diameter area of the core. The core particularly solves the problem of elongated edges on a wound film of heat shrinkable thermoplastic material caused by differential shrinkage about a core.
