No. A knot-tying machine according toclaim 4, wherein the elongate member of the knot-tying assembly ismounted for rotation on an axis perpendicular to the axis ofrotation of the package.An embodiment of the method according to the invention of tying a knot in a strand carried on a package comprises the steps of mounting a package having a supply of a strand material with an exposed free end wound onto an outer surface of the package, gripping and holding a length of the strand adjacent the exposed free end of the strand, forming a loop in the length of the strand adjacent the exposed free end of the strand and intermediate the gripper and the package by relative rotational movement of the package and a loop-forming assembly, and forming a slip-knot in the loop of the strand formed in the strand of a type adapted to be subsequently removed when desired by pulling on the free end of the strand.It is another object of the invention to provide a knot-tying machine which ties an easily-removable slip-knot in a yarn end.A knot-tying machine, including a package support for holding a package having a supply of a strand material with an exposed free end wound onto an outer surface of the package, a strand gripper for releasably gripping and holding a length of the strand adjacent the exposed free end of the strand, a loop-forming assembly for forming a loop in the length of the strand adjacent the exposed free end of the strand and intermediate the gripper and the package, the package support and the loop-forming assembly mounted for rotational movement relative to each other for forming the loop in the strand, and a knot-forming assembly for forming a slip-knot in the loop of the strand formed by the loop-forming assembly adjacent the free end thereof, the slip-knot being adapted to be subsequently removed when desired by pulling on the free end of the strand. In one type of textile winder, packages are doffed from the individual winding stations and carried by a conveyer to one end of the machine, where the automatic knot-tying machine 10 finds the free end of the yarn “Y” and ties it into a slip knot in accordance with the invention disclosed herein.FIG. A knot-tying machine according toclaim 1, wherein said knot-forming assembly includes:According to yet another preferred embodiment of the invention, the step of forming the loop comprises the step of rotating a loop-forming assembly about an axis of rotation of the package in spaced-part relation thereto for capturing and separating a length of the strand from the surface of the package.After insertion of the knot, the package is rotated 90 degrees and a label is inserted into the interior of the package. From the starting position shown in FIG. A gripper 16 holds the free end of the yarn “Y” taut during knot formation. 19; and6. Yarn to form the loop is unwound off of the package “P” during rotation of the loop-forming tube 24. China Knot Tying Machine manufacturers - Select 2020 high quality Knot Tying Machine products in best price from certified Chinese Wire Coil manufacturers, China Rebar suppliers, wholesalers and factory on Made-in-China.com A knot-forming assembly is carried by the elongate member for capturing a second length of the yarn separated from the surface of the package and pulling the second length of yarn through the secondary loop and thus forming a slip-knot in the loop of the strand formed by the loop-forming assembly adjacent the free end thereof.
A gripper 16 holds the free end of the yarn “Y” taut during knot formation. The mandrel 11 remains stationary. 11, the swing arm 27 rotates around the package “P” and in so doing passes the yarn “Y” being held by the gripper onto the loop-forming tube 24.
