Abstract: Apparatus for freeing the bottom wraps and the downwinds of yarn from a textile bobbin to provide a free yarn end in preparation for subsequent unwinding of the bobbin, including three bobbin engaging and rotating rollers arranged in a triangle with two of the rollers being driven and the third roller being movable into engagement with the top of the bobbin to rotationally support the bobbin by the three rollers. The axes of rotation of two of the three rollers are skewed with the skewing being related to the direction of rotation to cause an upward component of rotational support of the bobbin to raise it against a stop member and away from a bottom support plate that is then pivoted downwardly to form an opening to accommodate jets of compressed air acting somewhat downwardly against the bobbin to free the downwinds and bottom wraps of yarn.

Abstract: Device for feeding cops to winding stations of a winding machine includes an endles conveyor belt traveling in axial direction past the winding stations and feeding thereto, as needed, cops carried by a forward traveling upper run of the conveyor belt, the endless conveyor belt having a reversing location beyond the last winding station of the machine, a first reversing device located between the last winding station and the reversing location of the conveyor belt, the first reversing device having means for removing from the forward traveling upper run of the endless conveyor belt cops which had not been fed to the winding stations and for depositing the cops on a returning lower run of the endless conveyor belt, and a second reversing device in vicinity of the returning lower run, the second reversing device having means for removing the cops from the returning lower run, and for transfering the cops to the forward traveling upper run of the endless conveyor belt.
