Abstract
Abstract A cable fairing system is disclosed which contains a rotatable cable strand opening die connected to a rotatable cable strand closing die by means of a hollow, slotted tube. Bearings respectively connected to brackets attached to a bench support said dies for rotation therein. A feed reel supplies multi-strand cable for threading through said dies and hollow tube, and a take-up reel receives the reconstructed cable after thrums have been inserted between the opened strands thereof by a human or other operator. A controlled motor drives said take-up reel at such speed as to pull the multi-strand cable through the aforesaid dies and tube and still allow the aforementioned thrums to be installed therein immediately prior to the reconstruction thereof.

Claim 6
Dependent Claim
45 words
The device of claIm 1, wherein said means connected to said cable for the pulling thereof through said multi-strand cable receiving, opening, separating, and closing means comprises: a rotatable take-up reel; and a motor connected to said rotatable take-up reel for the rotational driving thereof.
Claim 7
Dependent Claim
61 words
The device of claim 1, wherein said means connected to said cable for the pulling thereof through said multi-strand cable receiving, opening, separating, and closing means comprises: a rotatable take-up reel; a motor connected to said rotatable take-up reel for the rotational driving thereof; and an adjustable motor control connected to said motor for starting, stopping, and regulating the speed thereof.
Claim 8
Dependent Claim
37 words
The invention of claim 1, further characterized by means disposed adjacent to said multi-strand cable receiving, opening, separating, and closing means for inserting fairing thrums between the strands of said cable immediately prior to the closing thereof.
Claim 9
Dependent Claim
44 words
The device of claim 1, further characterized by adjustable brake means connected to said rotatable multi-strand cable containing means for regulating the speed and tension at which the cable contained thereby is received by the aforesaid cable strand receiving, opening, separating, and closing means.
Claim 10
Independent Claim
400 words
A system for installing fairing thrums in a multi-strand cable, comprising in combination: a rotatable feed reel upon which is wound the multi-strand cable in which fairing thrums are to be installed; a first rotatable die having an axis of revolution, a journal disposed equidistantly around said axis of revolution, a center core hole disposed through said first die along said axis of revolution, and a plurality of outer strand holes disposed through said first die in such manner as to be substantially equidistant from said axis of revolution; a second rotatable die having an axis of revolution substantially in alignment with the axis of revolution of said first rotatable die, a journal disposed equidistantly around said axis of revolution, a center core hole disposed through said second die along the axis of revolution thereof, and a plurality of outer strand holes disposed through said second die in such manner as to be equidistant from the axis of revolution thereof; a hollow pipe connected between said first and second rotatable dies along extensions of the axes of revolution thereof in such manner as to be in alignment with the center core holes thereof and to effect rotation thereof as a unit; an elongated slot located in the wall of the aforesaid hollow pipe; a first bearing disposed around the journal of said first die in such manner as to effectively allow relative rotation therebetween; a second bearing disposed around the journal of said second die in such manner as to effectively allow relative rotation therebetween; a pair of mounting brackets respectively attached to said first and second bearings; a bench connected to said pair of mounting brackets for support thereof; a clamp attached to said multi-strand cable after the center core strand and the outer strands thereof have been threaded through the aforesaid core and outer plurality of holes in said first die, said hollow pipe, and said second die, respectively, for effecting the urging thereof toward a closed multi-strand cable condition as it is pulled along; a rotatable take-up reel connected to the clamped end of said closed multi-strand cable for the pulling and storing thereof thereon; a motor connected to said take-up reel for the rotational driving thereof, so as to effect the pulling and storing of said closed multi-strand cable thereon; and a motor control connected to the aforesaid motor for starting, stopping, and speed regulation thereof.
