ABSTRACT:
Each of the spinning stations is provided with a cradle having a pair of arms which are pivotally mounted on a carrier. The service tender is provided with a pair of light beam emitter/receiver units so that when the tender is called to and aligned with a specific spinning station one emitter/receiver unit is able to detect the presence of the carrier in a raised position while the second emitter/receiver unit is able to detect the presence or absence of a yarn package or bobbin tube on the cradle.
The service tender is operable in response to the combination of signals received from a calling station at the spinning station and the signals received from the emitter/receiver units.
