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.
