Title: Thermoplastic pipe bends cut to length are mechanically handled - by turntable onto work-table in correct alignment
Inventor: STEWING ALBERT
IPC: B29C48/09
Filed: 1973-09-11
Abstract: A device for manipulating pipe bends as they are cut to length from a continuously extruded curved pipe is used for passing them in their correct orientation to a station where a socket is formed on each bend. The extruded tube is cut to length and the cut length, resting on a turn-table, is swung about an axis into alignment and discharged onto a fixed work-table at a lower level. Here it is taken over by tongs from below, which advance it in the conveying direction. The cutting operation is initiated when the pipe length held on the turntable by a holding-down clamp, reaches a stop. Cylinders receive the cut length from the turntable. Uses for extruded thermoplastic pipe bends. Rapid and accurate mechanical handling of cut lengths is achieved.
