ABSTRACT:
A transferring apparatus for a textile spinning machine for transferring empty tubes and full yarn packages between the spindles on which yarn packages are built and an endless belt for supplying the tubes and discharging full yarn packages. The transferring apparatus includes a tube gripping assembly, a device for vertically moving the tube gripping assembly, a device for laterally moving the tube gripping assembly, and a device for controlling the apparatus to position the tube gripping assembly in a predetermined position relative to the textile spinning machine. The controlling device measures the movement of an operating component, compares the measured value with a predetermined value, and stops the movement of the transferring apparatus in response to an indication that the measured value and the predetermined value are equal. The movement of the operating component corresponds to the vertical and/or lateral movement of the tube gripping assembly. The transferring apparatus can be readily provided with the limits of movement of the tube gripping assembly without the need for mechanical limit switches or the like.
