An air cylinder is mounted on the central portion of a plurality of vertical frames disposed between upper and lower frames in a circular arc shape, and a vertical groove is formed in each of the vertical frames to allow a blade inserted therein to be connected to the air cylinder. Also, left and right guide rods are mounted at the outside of a through-hole defined in the center of the upper frame, and a corrugated tube holder and a support are inserted and elastically mounted into the left and right guide rods using springs. A stepped protrusion formed on an upper end of a corrugated tube is inserted into and supported by a recessed groove and a semicircular groove defined in a central portion of a vessel holder. Thus, the manufacturing device for the corrugated tube of a compression spray vessel has a simple structure and very fast corrugation working speed. Also, the device is reduced in manufacturing costs and has almost no malfunction, and is free from accidents of a worker. |
