Abstract
Abstract The provision winding machine for tape includes a takeup spindle on which the tape from a letoff source is wound, a reciprocating traverse guide having sidewalls for guiding the tape in passing to the takeup spindle, a tape guide bar movably positioned in the tape path leading from the letoff source, and means for altering the relative positions between the tape guide bar and the takeup spindle during winding to assist the tape to move with the traverse guide away from its natural straight line path on the outward strokes, and to retard the movement of the tape back towards the natural straight line path on the return strokes, thereby preventing the tape from being crushed against the sidewalls of the traverse guide.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
A precision winding machine for tape comprising a takeup spindle on which the tape from a letoff source is wound a reciprocating traverse guide having sidewalls for guiding said tape in passing to the takeup spindle; a tape guide bar movably positioned in the tape path leading from the letoff source; and means for altering the relative positions between the tape guide bar and the takeup spindle during winding to assist the tape to move with the traverse guide away from its natural straight line path on the outward strokes, and to retard the movement of the tape back towards the said straight line path on the return strokes, thereby preventing the tape from being crushed against the sidewalls of the traverse guide.
Claim 2
Dependent Claim
123 words
A precision winding machine for tape comprising a takeup spindle on which the tape from a letoff source is wound a reciprocating traverse guide having sidewalls for guiding said tape in passing to the takeup spindle; a tape guide bar movably positioned in the tape path leading from the letoff source; and means for altering the relative positions between the tape guide bar and the takeup spindle during winding to assist the tape to move with the traverse guide away from its natural straight line path on the outward strokes, and to retard the movement of the tape back towards the said straight line path on the return strokes, thereby preventing the tape from being crushed against the sidewalls of the traverse guide.
Claim 3
Dependent Claim
29 words
A tape winding machiNe as claimed in claim 1, in which the tape guide bar is positioned to engage the tape prior to its engagement by the traverse guide.
Claim 4
Dependent Claim
22 words
A tape winding machine as claimed in claim 1 in which the tape guide bar has the shape of a wide-angled V.
Claim 5
Dependent Claim
33 words
A tape winding machine as claimed in claim 3 in which the tape guide bar is of circular cross section, and is pivoted to the machine framework adjacent the apex of the V.
Claim 6
Dependent Claim
38 words
A tape winding machine as claimed in claim 4 wherein the bar is arranged so that when one arm of the V is parallel to the axis of the takeup spindle the other arm slopes towards the spindle.
Claim 7
Dependent Claim
57 words
A tape winding machine as claimed in claim 1 in which the traverse guide is reciprocated by a pair of gears mounted on a pivoted plate, the gears being driven in opposite directions; and means to pivot the plate to position in which the gears alternately engage a corresponding gear on a screw driving the traverse guide.
Claim 8
Dependent Claim
92 words
A tape winding machine as claimed in claim 1 in which the means to alter the relative positions of the tape guide bar and the spindle operates only when the traverse guide has reached either end of its reciprocating motion; and in which the means for altering the relative positions of the tape guide bar and takeup spindle comprises a fluid actuated piston and cylinder, and valve means associated with the drive for the traverse guide to reverse the direction of movement of the piston at each end of the traverse movement.
