Apparatus for the control of relative strand movement, without significantly affecting or altering strand tension, on a braiding machine with two sets of carriers for a strand supply bobbin being rotated in opposite directions and being generally axially aligned, as a set of front and rear strand carriers and supply bobbins. A set of rear strands pass through peripheral and radially arcuate slots in a carrier mounting table and are guided prior to movement into the slot by a set of cam actuated swing arms movable in a common plane perpendicular to the machine axis. The rear strands move through an arc segment relative to the machine axis for interweaving with a set of front strands. The interwoven rear and front strands are led to a circular ring at the front of the machine having an effective diameter coincident with the rotational axis of the front bobbins. The interwoven strands are then pulled from the machine to a "work center" for tight braiding around a core or mandrel.
In a braiding machine having a set of rear carriers for a strand supply bobbin mounted on the rear side of a first table for rotation in one direction, the strands from a set of supply bobbins on said rear carriers passing through a set of peripheral slots in said first table, a second table in front of said first table, a set of front carriers for a strand supply bobbin mounted on and driven around the front side of said first table by rotation of said second table, a central axis stationary shaft for rotatable mounting of said first and second tables thereon, a drive mechanism for rotating said first and second tables in opposite direction, and an apparatus for control of moving strands from the sets of supply bobbins on said rear and front carriers during movement thereof around and along said central axis stationary shaft and toward the "work center" of said braiding machine, said apparatus having a set of said first table peripheral slots which are radially arcuate for movement of a set of strands from said rear carriers through an arc segment relative to the axis of said stationary shaft, said apparatus further comprising:
Apparatus for use on a braiding machine having a set of carriers for a strand supply bobbin mounted on the rear side of a rotatable table having a set of peripheral radially arcuate slots therethrough, another set of carriers for a strand supply bobbin rotatably mounted in front of said table, and a central axis stationary shaft rotatably mounting said table, said apparatus including a control element adjustably positioned coaxially around said central axis stationary shaft behind the rear side of said table, a variable radius cam track carried by said control element radially inwardly of said set of rear carriers, said cam track having a set of alternating inner and outer dwell portions connected by a ramp portion, and a set of strand guide mechanisms, each said strand guide mechanism having:
In a braiding machine having sets of carriers for a strand supply bobbin mounted for rotation around a central axis stationary shaft, a table mounted for rotation around said shaft in front of said sets of carriers, a drive mechanism for rotating said table in one direction, and a circular braid ring carried by a hub mounted on said stationary shaft in front of said table, an additional drive mechanism for rotation of said braid ring and hub in a direction opposite to the direction of rotation of said table, said braid ring drive mechanism comprising:
