Patent ES-372059-A1 (ES)
Title: Method for making thermoplastic synthetic resin hollow structure articles
IPC: B29C48/11
Filed: 1969-09-30
Abstract: A method for continuously making hollow structures of thermoplastic synthetic resin. The resin is heated and extruded to form a continuous hollow structure.
