Textilmaschine

摘要

A textile machine with switchable multistage gearing for the adjustment of the turning speed ratio between rotating parts of the textile machine, such as drives, spindles, delivery members, stretching members, and the like, having a control system for switching the respective couplings of the multistage gearing upon a command from a decimal feed-in means having the capability of storing the desired fed in turning speed ratio. The decimal input is converted into a binary coded signal independent of time and compared in a comparison stage with pre-programmed signals representative of settable turning speed ratios.
