ABSTRACT:
A glass tube bending apparatus according to the present invention includes a drum for bending a heated/softened glass tube into a circular shape, a first driving device, coupled to the drum, for moving the drum straight, and a second driving device, coupled to the drum, for rotating the drum in a direction, and a control for independently controlling the rotating speed and the moving speed of the drum. According to this apparatus, the operation speeds of rotating and moving of the drum can be controlled independently. Therefore, distortion of glass tubes can be decreased, and thermal bending of tubes can be performed with high precision. Further, various sorts of glass tubes can be treated. Still further, since the first driving device and the second driving device are operated in synchronism, the precision of the thermal bending of glass tubes is enhanced.
