ABSTRACT:
A new locking arrangement is disclosed for effectively locking bobbins in place on associated roving machine spindles. The locking arrangement includes a body that is drivingly connected to the spindle and has torque transmitting surfaces coacting with the bobbin. A deformable retainer is moveably coupled to the body. An over center cam is moveably coupled to the body and is coactable with the retainer in retainer compression and a retainer release position. When the cam is in the compression position, the retainer is deformed into a lock producing position securing the body and the bobbin in a torque transmitting relationship with forces which include an axial vector urging the members together. When the cam is in a release position, the bobbin can be removed from the spindle.
