Abstract
A bobbin control mechanism for a strand carrier for operational mounting before a braid point on a strand fabricating machine. A carrier base member (28) has an axial post (29) for rotatable mounting of a bobbin. The carrier has a series of posts radially around the axial post, a series of guide rollers, a mechanism for tensioning a moving strand on the guide rollers and a reciprocating rod (55) projecting into the base member and reacting to strand tension. The bobbin control mechanism (60) includes a finger cam (61) connected to the reciprocating rod, a free cam (62) movable by the finger cam, a ratchet gear (63) rotatable around the base of the axial post, a first pawl cam (64) preventing clockwise rotation of the ratchet gear, and a second pawl cam (65) preventing counter-clockwise rotation of the ratchet gear. A detachable cover plate (66) around the axial post closes off the interior of the base member. A spool drive ring (69) is connected to a spool control side flange (25) above the axial post and to the ratchet gear through the cover plate.
