Abstract

A yarn feeding apparatus for yarn-processing textile machines such as circular knitting machines has a feed element which advances the yarn with its circumference. The feed element is rotatably supported on a holder which is arranged to be secured on a carrier and has yarn guide and/or monitoring devices for the yarn being fed to and/or delivered by the feed element. The feed element is driven by a regulated electric motor disposed on the holder. To provide for yarn feeding apparatus which is both compact and inexpensive, the electric motor is a stepping motor coupled to at least one yarn feed element, which advances a yarn in a slip-free manner with its circumference, each element having its own yarn guide and monitoring devices associated with it.
