ABSTRACT:
An apparatus for replacing full bobbins on spindles of a continuous spinning machine by empty tubes situated on fixed pegs near the spindles, and arranged in a plurality of consecutive spinning positions in the spinning machine, has a gripping mechanism for simultaneously removing the full bobbins and the empty tubes of two consecutive spinning positions from the spindles and pegs respectively, and for simultaneously replacing the full bobbins and empty tubes on the pegs and spindles, respectively, of the two consecutive spinning positions. The gripping mechanism is of the quadruple mechanism type having four separate grippers, respectively for engaging the full bobbin of one spinning position; for engaging the empty tubes of the one spinning position; for engaging the full bobbin of the other spinning position, and for engaging the empty tube of the other spinning position. There is also a mechanism for moving the grippers vertically in the direction of longitudinal axes of the spindles and pegs, respectively, and one for rotating the grippers about a vertical axis by 180.degree. in one direction about the center of a parallelogram defined by the points of intersection between a horizontal plane and the axes.
