Abstract
A carrier for a strand supply bobbin used on strand fabricating machines. The carrier has a raisable and generally circular cap (32) housing a sleeve (37), a disc (38), a ring (39), a compression spring (40), a leaf spring (41), an actuator rod (42), a collar nut (43), a retainer cup (44), a planar reaction surface (45), an actuator plug (46) and freely movable force transmitting elements (47), as operative elements for bobbin control during letoff of strand material. Radial movement of the force transmitting elements (47), to brake or clutch the supply bobbin is determined by (i) the position of the bobbin control actuator rod (42), (ii) the position of the bobbin control actuator rod (46), and (iii) the position of the bobbin control disc (38) within the raisable cap (32) on the carrier.
