Abstract

A thermally-operated switch (see Group XXXVII) is used to control the temperature of a number of hot plates on a draw-twisting machine for hot stretching yarns of polyethylene terephthalate. It is stated that a temperature of 170.5 DEG C., for example, may be maintained within \sB 1 DEG C.
