Abstract
On a textile machine, arL empty spool (12) is conveyed along a multiplicity of spool stations (1) situated next to one another. In a predetermined position relative to a grasping apparatus (3) the said empty spool (12) is stopped and is picked up by said grasping apparatus (3), and held by its circumferential surface. After its being lifted by the grasping apparatus (3), the spool (12) is retained in an axial alignment. This retention is discontinued, before the spool (12) is released at the spool station (1) where it is required. For the execution of this procedure, a retaining arrangement (8), composed of stopping devices (4 and 5), is provided for the spool (12) which is held by the grasping apparatus (3). The retaining arrangement (8) idles in a location outside of the transport path which the empty spool (12) will occupy when held. From this idle position, the retaining arrangement (8) can be brought into an operational position, in which it assures the correct axial position of the empty spool (12) which is being held by the grasping apparatus (3).
