ABSTRACT:
The servicing apparatus is mounted for running movement along, and for pivotal movement laterally of, a path of travel having a first section extending adjacent spinning units of the spinning machine and a second section extending adjacent an end cabinet of the spinning machine. During movement of the apparatus from the first and to the second section of its path of travel, it is pivoted laterally of such path to provide clearance between interfering components of the apparatus and the cabinet of the machine that would otherwise preclude movement of the apparatus along the second section of its path of travel. Pivotal movement of the apparatus is realized by a cam means so located as to not impede traffic adjacent the machine or access to the interior of its end cabinet, and as to minimize the magnitude of the force required to produce the aforesaid pivotal movement. In an alternative embodiment one of the interference-causing components of the apparatus is moved to a retracted position as the apparatus passes from the first and to the second section of its path of travel, as a result of which the clearance-producing pivotal movement of the apparatus may be of a lesser magnitude than would otherwise be required.
