Abstract

<PICT:1066102/C1/1> In glass tubing drawing apparatus which includes means for maintaining the outer diameter of the tubing T constant, a control system for adjusting the wall thickness comprises a gauge 55 for continuously producing a first signal 54 representing the entire annular cross-sectional area of the tubing T, a pre-set signal 58 representing the annular cross-sectional area of tubing of the required outer diameter and wall thickness, means 57 for continuously comparing the signals 54, 58 and continuously producing a third signal 59 representing the deviations in wall thickness, and speed control means 65 responsive only to the third signal 59 for adjusting the speed of draw of the tubing T by tube drawing means 68 to adjust for the deviations in wall thickness. The means for maintaining the outer diameter of the tubing T constant may be as disclosed in Specification 943,305 and the gauge 55 may be as disclosed in Specification 905,307.
