Abstract:

A method and apparatus for winding fiber glass roving, tape rope, and/or the like, on a mandrel. The apparatus includes a turntable rotatable in either direction about a vertical axis and carrying means for winding the reinforcing material on the mandrel in response to rotation of the turntable, the mandrel being located on the turntable axis. The machine also includes means for shifting the axis of a shaft carrying the mandrel angularly relative to a vertical position wherein the mandrel shaft axis coincides with the turntable axis. The apparatus further includes means for rotating the mandrel shaft about its axis in either direction, when the mandrel shaft is in its vertical position, to assist the rotation of the turntable in winding the reinforcing material about the mandrel. With this construction, the reinforcing material may be wound on the mandrel in a variety of patterns. Also disclosed are a method of making wound articles with the reinforcing material applied to a mandrel in various patterns, and various products made by the disclosed apparatus and in accordance with the disclosed method, including a T-shaped hollow article, such as a pipe fitting or a valve body, an elbow, a valve ball, and the like.
