Method and device for securing a reserve winding on a tube
First Claim
1. A device for securing a reserve winding on a tube supported by winding apparatus having a thread delivery source, drive means for rotating said tube causing said thread to be wound thereon, a traversing thread guide member for traversing along said tube causing said thread when grasped thereby to be uniformly wound along the length of said tube, and a thread-holding device disposed in the vicinity of a path of the thread from said thread delivery source to said tube for receiving and holding a portion of said thread, said device for securing a reserve winding comprising:
- an auxiliary thread guide disposed adjacent said tube in the region of said reserve winding between said thread-holding device and said tube for receiving a length of said thread extended from said thread source to said thread holding device and guiding said thread held by said thread holding device to said tube for forming said reserve winding;
thread-catching means carried by said tube for grasping said thread guided by said auxiliary thread guide, said auxiliary thread guide guiding thread extending from said thread delivery source to said tube to be grasped by said traversing thread guide while causing said thread extending from said thread holding device to said tube to form said reserve windings on said tube; and
means for movably carrying said auxiliary thread guide adjacent said tube for movement towards the center of said tube and means for producing a free end in said thread extending to said thread holding device, said auxiliary thread guide including a thread-deflection guide for deflecting said thread guided thereby towards the center of said tube when so moved causing said free end of thread to be covered by thread grasped and laid by said traversing thread guide securing said reserve winging on said tube.

Abstract
A device and method for securing a reserve winding of thread on a tube supported on winding apparatus having a main thread guide and a thread delivery source wherein a reserve winding is formed from thread extending to a thread-holding device and thereafterwards severed with the free end of the reserve thread deflected toward the longitudinal center of the tube and covered with thread subsequently laid by the main thread guide.

6. A device for securing a reserve winding on a tube supported by winding apparatus having a thread delivery source, drive means for rotating said tube causing said thread to be wound thereon, a traversing thread guide member carried adjacent said tube longitudinally movable for traversing said tube causing said thread when grasped thereby to be uniformly wound along the length thereof, and a thread-holding device disposed in the vicinity of the path of the thread from said thread delivery source to said tube for receiving and holding a portion of said thread extended from said thread source, said device for securing a reserve winding comprising:
-
a thread catching projection carried on said tube oriented in the direction of rotation of said tube; a holder assembly; auxiliary thread guide means carried by said holder assembly including a first thread-deflection guide for receiving a length of thread extending to said thread-holding device and a second thread deflection guide spaced from said first deflection guide between which said thread is held substantially parallel with said tube with the remaining length of thread extended from said second deflection guide to said thread delivery source; a space defined between said first and second thread-deflection guides through which said thread-catching projection passes to grasp said thread held therebetween; and means for supporting said holder assembly adjacent said tube within the working range of said thread-catching projection means causing said thread held between said first and second deflection guides to be grasped by said thread-catching projection, said second thread deflection guide causing said thread extending from said thread delivery source to said tube to come within the range of said traversing thread guide and to subsequently be grasped by said traversing thread guide whereby said thread is uniformly wound along the length of said tube while said first thread-deflection guide causes said thread extending to said thread holder device to form said reserve windings. - View Dependent Claims (7, 8, 9, 10, 11)
