ROTATABLE ARTICLE WHICH HAS A FIAT SHAPE

摘要

A continuous filament impregnated with a hardenable polymer is wound on a mandrel between two detachable sideplates of a mold so as to form a part of revolution having a longitudinal dimension in a direction parallel to the axis of revolution which is of small value compared with its radial dimension, the proportion of polymer being substantially constant from the vicinity of the mandrel to the periphery of the part.
