Abstract

PURPOSE: A glass tube is held at the top end and taken out along the locus corresonding to a desired shape and simultaneously pushed out with the tail end held, thus forming a glass tube with any accurate bent shape such as circular fluorscent lamp.
CONSTITUTION: The top end of bulb A is passed through guide hole 16 and heater 10 and the tail end and top end are held with chuck 7 in feeding mechanism 2 and chuck 27 in taking-up mechanism 17 respectively. The bulb A is a little pressurized at the inside. The heater 10 evols heat to soften the bulb A locally. Then, the bulb A is pushed with shifting bed 3 and vertically revolving shaft 26 is made to revolve by 180°C so that the top end moves along a semisphere locus to form a U-shape in the vertical direction. The shifting bed 23 in straightly moving mechanism 22 proceeds to form the stragiht part of a certain length and bulb A is bented horizonrally by 180°C revolution of the revolving arm 20 in horizontally revolving mechanism 18. These operations are repeated to form complicately bent glass bulbs with high accuracy and steadiness.
