An apparatus for high speed attachment of a cord to a piece of receiving
material is characterized by one or more pins which engage the cord,
pierce the receiving material and draw the cord through the receiving
material from the first side to a second side thereof so that open loops
are formed in the cord on the second side of the receiving material. The
pins may be implemented as a push pin and spreader pin pairs movably
mounted relative to each other and each of which are adapted to grasp the
cord and penetrate the receiving material. The loop(s) are formed as the
push pin and spreader pin move relative to each other. The apparatus
further comprises a floating shuttle, not attached to the frame of the
apparatus but supported by a series of gear assemblies. The pins move
relative to the shuttle in a single direction causing the shuttle to
engage an end portion of the cord, drawing the cord through the open loops
so as to complete the lacing stitch of the cord through the receiving
material. The apparatus operates without any significant reciprocating
motion, resulting in a process that can attach a cord to a piece of
receiving material at extremely high speeds. The floating shuttle may be
applied in any situation where a strand of material such as cord, thread,
wire, or fiber is to be attached to a receiving piece of material.
