Abstract
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. The package support may be stationarily mounted and the loop-forming assembly mounted for rotation around the periphery of the package support for capturing the length of the strand adjacent the exposed free end of the strand for forming a loop therein.
