Flat glass fibre built up material - made by coiling round barrels

摘要

The plastic binder sprayed glass fibre thread from a movable glass thread making melting furnace is coiled onto the circumference of a barrel. When an adequate layer has been built up the thread is deflected to an adjacent barrel without stopping the thread making and another layer of material is built up. In the meantime the first barrel is arrested to permit removal of the material to make it ready for another coiling sequence. Pref. arrangement comprises two coaxial barrels. between which is provided a coaxial roll which may be moved close to either barrel for transferring the continuously supplied thread.
