ABSTRACT:
An apparatus and method for measuring yarn storage at a spindle assembly station in a textile yarn processing machine, such as a two-for-one twister or the like, in which each station includes a spindle assembly for carrying a package of yarn to be withdrawn and processed while producing a rotating balloon of the yarn around the package and having a driven rotor mechanism including a yarn reserve disc providing a passageway for the yarn therethrough from the package and for storing a length of the yarn therearound prior to formation of the balloon of yarn, as follows. First and second electrical pulse generating devices generate electrical pulses in response to the frequency of rotation of the rotor mechanism and the balloon of yarn, respectively. A mechanism is connected with the pulse generating devices for counting the generated pulses and for evaluating the time t.sub.B required for the first pulse generator to generate a predetermined number of pulses and the time t.sub.S required for the second pulse generator to generate a predetermined number of pulses and for calculating and displaying the time difference .DELTA.t = t.sub.B - t.sub.S as a measure of yarn storage on the reserve disc.
