Abstract: Apparatus movable along a spinning frame to doff full bobbins from the spindles thereof and to don empty bobbins onto such spindles. Low pressure pneumatic sensors are provided for emitting a stream of low pressure air into the path of movement of selected elements of the apparatus and generating a pneumatic signal each time a stream of low pressure air is interrupted by the movement of such elements, and a low pressure pneumatic control system receives the pneumatic signals and operates the selected elements of the apparatus in a predetermined sequence.
