  • Method of making a tube using a cylinder air cooled heat welder
    Patent number: 8500935
    Abstract: A method of welding a thermoplastic sheet, having a first side and a second side, into a cylinder, the method comprising the steps of folding the thermoplastic sheet into a cylinder such that the first side and the second side overlap, positioning the thermoplastic sheet in a cylinder tube having a longitudinal opening such that the overlapping portions of the first and second sides of the thermoplastic sheet are aligned with the longitudinal opening, and activating a heat welder so that a press of the heat welder moves into the longitudinal opening of the cylinder tube and presses the thermoplastic sheet against an opposing surface to weld the overlapping portions of the first and second sides.
