ABSTRACT:
In the apparatus of this invention a plurality of cylindrical matrices 2 are used to form tubular sleeves of elastomeric material to be later cured and cut into short segments to be used as belts, usually toothed belts. A coiling station 8 places a reinforcing fiber helically around the entire length of the sleeve. The matrix having the coils is then turned to a vertical position by a transfer member 28 and transferred, by means of an adjacent rotating platform 6 to a winding station 9 for application of a sheet of elastomeric material over the thread. The matrix having the completed but uncured sleeve is then placed back on the rotating platform. The coiling station and the winding station each have a tilting member 34 or 43 with two pairs of arms 39 or 52 so that while a completed matrix is swung out of the working position, a fresh matrix is swung into position.
