Glass roving is directed through a soaking tub which is supplied with resin and a setting agent, and trained as a flat-pressed band to a forming unit. The forming unit comprises a two-part mold which is formed by the flange portions of two mold discs and becomes automatically coupled in its closing position. The mold discs are supported on separate coaxial shafts, each of which is associated with a drive for opening and closing the mold. One of the mold parts comprises a cylindrical portion by which, upon opening the mold, the finished sleeve is supported. Pusher pistons provided at this mold part becomes effective automatically as the mold is opened to push off the molded sleeve. All working, drive and conveying means, as well as all switching and control elements are under the control of a common programmable central unit. |
