Title: Process control method for a machine for manufacturing thermoplastic tubes

Abstract: A machine for manufacturing thermoplastic tubes from hollow thermoplastic sleeves by a variety of different manufacturing processes. The machine is a single apparatus having an indexing table with a plurality of mandrels for holding hollow thermoplastic sleeves for the purpose of transporting the same around a closed manufacturing path. The manufacturing path of the machine is a series of stations which are mechanical devices for carrying out the manufacturing steps necessary to produce tubes from thermoplastic blank sleeves. The stations of the manufacturing path are modular so that they may be removed, added or rearranged; may be optionally connected to a process logic controller and may optionally have sensors for information feedback to the PLC device.
