Abstract
A workpiece transfer arm for supporting and moving a workpiece from one position to another has a telescopic arm one end of which is secured to a mounting bracket and the opposite end of which carries a workpiece support for engagement by the workpiece. The telescopic arm has a rod accommodated in a sleeve. The rod has a plurality of annular grooves occupied by a thermoplastic adhesive which, when at ambient temperature, is solid and fixes the rod in the sleeve. At elevated temperatures, however, the adhesive liquefies and enables relative movement between the sleeve and the rod to enable the position of the workpiece support to be adjusted.
