Abstract: This invention is directed to a manipulator for automatically supplying centrifuge machines for rotating bobbins of yarn in which the manipulator includes a carriage equipped with stop wings and tightening arms which grip the bobbins conducted to the carriage by a conveyor and wherein the carriage moves the bobbins to the baskets of the centrifuge machines and thereafter returns to its initial position while flaps mounted on the carriage cover the centrifuge machine as the bobbins are rotated therein and thereafter the flaps urge the bobbins from the centrifuge machines to a receiver plate.

Abstract: A device for loading and unloading a rotating basket in a centrifuge for spin drying bobbins of yarn wherein a hub is provided centrally of the basket and which guides an annular bearing plate which is vertically shiftable with respect to the basket so as to be selectively engageable with and supportive of a bobbin of yarn which is lowered into the basket, subjected to centrifugal action, and thereafter raised to a discharge position above the basket.

Abstract: The turntable 1 bears eight rods 3 on which are mounted stacks of packages 4, which are brought on slides 20. The latter recoil each time to allow the stack to drop onto the table 19, then advance to push the lower package 14 towards a drying station where a jack 25 descends thereon and applies it on the rotating plate of an individual drying machine. This plate lowers inside a vessel; it rotates to ensure drying; finally, it rises and the dried package is pushed by the following one onto a corridor 28 which takes it to an evacuation conveyor 27. The drying stations may be disposed in a circle and various means are provided to ensure guiding of the packages between the turntable 1 or equivalent and the various stations.
