Kind Code:
B2
Abstract:
A tire tube making apparatus is to continuously apply tube valves onto a tube material around air introducing bores perforated in an upper half portion of the tube material. The apparatus comprises: a conveyor mechanism for conveying a tube material; a perforating mechanism for perforating air introducing bores longitudinally equally spaced in an upper half portion of the tube material; a valve feeding mechanism for intermittently feeding a tube valve one by one to a predetermined position above the line passing through the air introducing bores perforated in the tube material which is continuously conveyed by the conveyor mechanism; a valve transferring mechanism for suckingly holding the tube valve fed by the valve feeding mechanism to transfer the tube valve one by one on the air introducing bore in synchronism with the transfer of the air introducing bore of the tube material; and a valve urging mechanism for detecting the tube valve transferred by the valve transferring mechanism to urge the tube valve against the tube material for a predetermined period of time in synchronism with the transfer of the tube valve.
