Abstract
Abstract The invention relates to a bobbin winding machine for yarn products in which the yarn is traversed reciprocably during winding by means of a traversing device guided in an endless manner over two guide shafts and incorporating a freely rotatable yarn guide which thus adopts its own rotary position suited to the path of the yarn at any particular moment. The traversing device may conveniently consist of an endless flexible belt or a length of coil spring the ends of which are joined to form an endless unit. The belt or spring may be varied in length by stretching to control the winding length.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
Winding machine having a yarn guide for reciprocating lengthwise along a bobbin, comprising spaced guide shafts; traversing drive means guided over said guide shafts in an endless manner and rotatably driven means for adjusting the effective length of said traversing drive means; a yarn guide directly mounted at the traversing drive means; the traversing drive means being disposed in a plane substantially parallel to the path of yarn passing through said yarn guide; said guide being pivotably mounted to said traversing drive means such as to permit the yarn guide to pivot about an axis substantially perpendicular to the plane of the traversing drive means; and said traversing drive means being flexible in the longitudinal direction thereof so as to permit adjustment of the effective length of said traversing drive means.
Claim 2
Dependent Claim
131 words
Winding machine having a yarn guide for reciprocating lengthwise along a bobbin, comprising spaced guide shafts; traversing drive means guided over said guide shafts in an endless manner and rotatably driven means for adjusting the effective length of said traversing drive means; a yarn guide directly mounted at the traversing drive means; the traversing drive means being disposed in a plane substantially parallel to the path of yarn passing through said yarn guide; said guide being pivotably mounted to said traversing drive means such as to permit the yarn guide to pivot about an axis substantially perpendicular to the plane of the traversing drive means; and said traversing drive means being flexible in the longitudinal direction thereof so as to permit adjustment of the effective length of said traversing drive means.
Claim 3
Dependent Claim
40 words
Winding machine according to claim 1, in which the yarn guide is rotatably mounted in a sleeve on the traversing drive means about an axis parallel to the guide shafts and incorporating means to hold the yarn guide in position.
Claim 4
Dependent Claim
28 words
Winding machine according to claim 2 in which the traversing drive means consists of a belt and the sleeve is incorporated in the cross section of the belt.
Claim 5
Dependent Claim
22 words
Winding machine according to claim 3, in which the belt consists of a vulcanizable material and the sleeve is vulcanized in position.
Claim 6
Dependent Claim
32 words
Winding machine according to claim 2, in which the traversing drive means consists of a coil spring connected at its ends and in which the sleeve is secured to the coil spring.
Claim 7
Dependent Claim
18 words
Winding machine according to claim 2, wherein the inner surface of the sleeve consists of a sintered product.
Claim 8
Dependent Claim
29 words
Winding machine according to claim 1, wherein the yarn guide consists of a circular pin having a semispherical head incorporating at least one slot adapted to receive the yarn.
Claim 9
Dependent Claim
39 words
Winding machine according to claim 1, in which the yarn guide is of cranked shape having offset pin elements one of which is rotatably supported in the traversing drive means and the other is guided in a slide member.
Claim 10
Dependent Claim
21 words
Winding machine according to claim 1, in which said adjusting means includes means for adjusting the spacing between said guide shafts.
Claim 11
Dependent Claim
60 words
Winding machine according to claim 1, in which the guide shafts have a varying diameter along their length, said traversing drive means comprising a belt, and said adjusting means including means for displacing said guide shafts so that the belt can operate at different diameters on said guide shafts to provide an alteration in the stroke of the yarn guide.
Claim 12
Dependent Claim
102 words
Winding machine according to claim 1, wherein the traversing drive means is mounted on a swing frame terminated by a roller which bears on the bobbin being wound, said frame being deflected by contact with the bobbin and providing a mounting for the traversing drive means, said traversing drive means being movable in a plane parallel to the path of the yarn passing over the surface of the frame towards the roller, and the yarn guide being freely rotatably mounted to adopt a rotary position in the traversing drive means dependent on the path of the yarn being wound on the bobbin.
