DEVICE FOR AUTOMATIC REPLACEMENT OF ROVINGFILLED BOBBIN WITH EMPTY TUBE PER GROUP IN ROVING FRAME

PURPOSE: To provide the subject service unit having such a scheme that the mutual spacing between grippers is altered along X-direction by the aid of the regulator for a gripping device doubling as a turning device and the mutual spacing between pegs is altered along Y-direction by the aid of the regulator possessed by a turntable to facilitate the exchange between full roving bobbins and empty tubes. CONSTITUTION: This service unit has such a scheme that grippers 5 are connected via three traction members to piston cylinder units 17, 18, 19 and the spacing between the grippers 5 is regulated along X-direction within the zone of a gripping device doubling as a turning device 30; and the spacing between pegs 51 and 51' to deliver full roving bobbins is altered to Y-direction by the aid of a regulator mounted on a turntable 9.
