Abstract: The apparatus is associated with a spinning or twisting machine and removes individual textile bobbin tubes from a reservoir, such as a container which contains such bobbin tubes. The container has in its lower portion a funnel-shaped structure through which the bobbin tubes move downwardly towards an opening. As is known, there is the danger that the bobbin tubes undesirably form "bridges" and thereby the further delivery of such bobbin tubes is interrupted. Such bridge formation is avoided by providing a break-up rod or bar which is arranged substantially horizontally and parallel to the broad sides of the container, in the interior and in the region above an opening of the container. The break-up rod or bar is supported in the longitudinal sides of the container with play on all sides and in a freely rotatable manner. The thickness of the break-up rod or bar and the thickness of the bobbin tubes are of the same order of magnitude.

Abstract: A stationary service unit at one end of an elongate spinning machine coacts with a supply carriage delivering bobbins wound with rovings from a flyer at a preparatory stage and loads these bobbins onto depending grippers which are movable, manually or automatically, on an overhead guide rack. The rack may form an endless loop about the machine bed or may be divided into two parallel sections flanking same; in the latter instance the service unit may be swingable about a vertical axis toward one or the other section.

Abstract: Bobbins wound with rovings from a preparatory stage are loaded onto a carriage which receives them on an orthogonal array of horizontal pegs and transports them to a holding station for transfer, one column at a time, to a service unit moving continuously or intermittently past a multiplicity of working positions of a ring spinning machine whose spindles draw the roving from bobbins on a supply rack. The service unit, whose primary function may be that of a yarn-tying device or a traveling air blower, has a vertical conveyor with stems alignable with the pegs of the carriage in the holding station for picking up the bobbins to be transferred and delivering them, individually, to storage areas at or near the supply rack where fresh bobbins are needed as determined by a sensor aboard that unit. The storage areas may have overhead grippers onto which a bobbin is pushed from an erected stem at the upper vertex of the vertical conveyor.
