Yarn winding apparatus

Claim 1

An apparatus for winding a yarn on a bobbin comprising: a guide for serving as a fulcrum of the traverse motion of a yarn; a mechanism for positively driving and holding said bobbin; a traverse mechanism interposed between said bobbin and said fulcrum guide further comprising a traverse guide having a narrow opening and a wide yarn holding portion through which said yarn may travel and reciprocating means for traversing said traverse guide along the direction of the generatrix of said bobbin so as to form a yarn package on said bobbin, said yarn moving to and fro in accordance with said traverse guide forming a path between said fulcrum guide and said bobbin; a yarn catching guide substantially parallel the moving direction of said traverse guide and substantially perpendicular to the plane of said yarn path, adjacent said traverse guide and movable along the moving direction of said traverse guide, having an inclined portion proximate said yarn path and having a hook portion adjacent said inclined portion for catching said yarn, said inclined portion positioned to intersect said yarn path, and said hook portion projecting away from said yarn path and being positioned more distant from the plane of said yarn path than said opening of said traverse guide.

Claim 2

An apparatus for winding a yarn on a bobbin comprising: a guide for serving as a fulcrum of the traverse motion of a yarn; a mechanism for positively driving and holding said bobbin; a traverse mechanism interposed between said bobbin and said fulcrum guide further comprising a traverse guide having a narrow opening and a wide yarn holding portion through which said yarn may travel and reciprocating means for traversing said traverse guide along the direction of the generatrix of said bobbin so as to form a yarn package on said bobbin, said yarn moving to and fro in accordance with said traverse guide forming a path between said fulcrum guide and said bobbin; a yarn catching guide substantially parallel the moving direction of said traverse guide and substantially perpendicular to the plane of said yarn path, adjacent said traverse guide and movable along the moving direction of said traverse guide, having an inclined portion proximate said yarn path and having a hook portion adjacent said inclined portion for catching said yarn, said inclined portion positioned to intersect said yarn path, and said hook portion projecting away from said yarn path and being positioned more distant from the plane of said yarn path than said opening of said traverse guide.

Claim 6

An apparatus for winding a yarn on a bobbin comprising: a guide for serving as a fulcrum of the traverse motion of a yarn; a mechanism for positively driving and holding said bobbin; a traverse mechanism interposed between said bobbin and said fulcrum guide further comprising a traverse guide having a narrow opening and a wide yarn holding portion through which said yarn may travel and reciprocating means for traversing said traverse guide along the direction of the generatrix of said bobbin so as to form a yarn package on said bobbin, said yarn moving to and fro in accordance with said traverse guide forming a path between said fulcrum guide and said bobbin; a waste spool which is disposed proximate and axially parallel said bobbin and on which said yarn is temporarily wound; a mechanism for rotatably supporting said waste spool and for positively driving said waste spool; a means for transferring said yarn further comprising: a yarn catching guide substantially parallel the moving direction of said traverse guide and substantially perpendicular to the plane of said yarn path, adjacent said traverse guide, having an inclined portion proximate said yarn path and having a hook portion adjacent said inclined portion for catching said yarn, and said hook portion projecting away from said yarn path and positioned more distant from the plane of said yarn path than said opening of said traverse guide; a fixed guide substantially parallel said yarn catching guide having an inclined portion projecting into an area proximate said yarn path, distant from said traverse guide; and a movable guide which is engaged with said fixed guide and which cooperates with said yarn catching guide; said fixed guide being secured so as to extend substantially in parallel with the moving direction of said traverse guide and having a length substantially equal to that between a position aligned with a part of said bobbin and another position aligned with said waste spool; and said yarn catching guide being adjacent to said fixed guide and arranged movably along the lengthwise direction of said fixed guide so that said incline of said yarn catching guide intersects said yarn path and so that said hook portion is movable between a position proximate said yarn path, distant from said traverse guide and a position aligned with said waste spool.

Claim 7

An apparatus for winding a yarn on a bobbin comprising: a guide for serving as a fulcrum of the traverse motion of a yarn; a mechanism for positively driving and holding said bobbin; a traverse mechanism interposed between said bobbin and said fulcrum guide further comprising a traverse guide having a narrow opening and a wide yarn holding portion through which said yarn may travel and reciprocating means for traversing said traverse guide along the direction of the generatrix of said bobbin so as to form a yarn package on said bobbin, said yarn moving to and fro in accordance with said traverse guide forming a path between said fulcrum guide and said bobbin; a waste spool which is disposed proximate and axially parallel said bobbin and on which said yarn is temporarily wound; a mechanism for rotatably supporting said waste spool and for positively driving said waste spool; a means for transferring said yarn further comprising: a yarn catching guide substantially parallel the moving direction of said traverse guide and substantially perpendicular to the plane of said yarn path, adjacent said traverse guide, having an inclined portion proximate said yarn path and having a hook portion adjacent said inclined portion for catching said yarn, and said hook portion projecting away from said yarn path and positioned more distant from the plane of said yarn path than said opening of said traverse guide; a fixed guide substantially parallel said yarn catching guide having an inclined portion projecting into an area proximate said yarn path, distant from said traverse guide; and a movable guide which is engaged with said fixed guide and which cooperates with said yarn catching guide; said fixed guide being secured so as to extend substantially in parallel with the moving direction of said traverse guide and having a length substantially equal to that between a position aligned with a part of said bobbin and another position aligned with said waste spool; and said yarn catching guide being adjacent to said fixed guide and arranged movably along the lengthwise direction of said fixed guide so that said incline of said yarn catching guide intersects said yarn path and so that said hook portion is movable between a position proximate said yarn path, distant from said traverse guide and a position aligned with said waste spool.
