ABSTRACT:
Device for the semiautomatic doffing of spools on cops provided with mushroom-shaped upper ends on a spindle bench in spinning with immovable closed or open flyers, characterized in that the bench upper plate has arms articulated thereto about vertical axes; the arms performing alternate angular movements in the horizontal plane with predetermined amplitude; the free end of each arm being provided with an immovable and open grip capable of penetrating into the volume of revolution of the corresponding flyer at the arrest of the spindle and coacting with the corresponding mushroom-shaped upper end of the cop following its rise to a predetermined height; a level R fixed to each pin, a rod pivotally connected to said levers to supply an alternating angular movement to the levers and means to lower the cops until there is a complete withdrawal of the spindles from the cops and the arms are rotatable in the opposite direction with respect to the previous rotation into the flyer's volume of revolution so as to take the spools out of the relative flyer's, and to conveniently accessibly position them ready for being removed.
