Apparatus for friction welding synthetic plastic container parts and the like
Abstract
Abstract Apparatus and methods for friction welding thermoplastic synthetic container parts of non-cylindrical configuration wherein a holder for one part is moved toward another holder for a second part to engage the respective surfaces of the parts to be friction welded, and wherein an eccentric shaft extending substantially perpendicularly to the surfaces to be welded together oscilates one of the holders and parts to relative to the other in the plane of engagement of the surfaces for a time sufficient to achieve a friction weld of the surfaces, sensing means being provided in the path of movement of the holder for the non-oscillated part which senses when the weld is achieved and is connected to disable the drive for oscillating the one holder, for withdrawing one holder relative to the other to permit unloading and reloading, and for releasing the vacuum employed by the holders to hold the parts.
