Abstract

Abstract A package of limp material is wound on the inside of a rotating drum or container having an opening in its wall substantially centrally of its length by feeding the material while conveyed by a current of air through and out of a tube which extends into an opening in one end of the drum which is reciprocated back and forth. The ratio between the number of rotations of the drum per unit of time and the number of reciprocations of the tube is substantially equal to an integral multiple of one-half, so that the limp material is laid up inside the drum in a series of figure-8 bights. The relative speeds of rotation and reciprocation are varied at one point in each layer of bights so as to leave a radial hole in the package opposite the hole in the container through which the inner end of the material is paid out for twistless payout. The container is foraminous and a suction is applied to the outside to assist in laying the material in the inside of the wall.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 129 words
A method of producing a package of limp material in a cylindrical container having an opening in the side thereof comprising feeding the material into the container, producing such relative movement between the material and the container as to lay up on the interior of the container a series of figure-8 bights of the material, and maintaining such material under longitudinal compression in the direction in which it is laid during the formation of the package, rotating said container, guiding said mAterial in movement axially of the container from end to end thereof, and interrupting the relative axial movement of the material and rotation of the container atone point so as to form a radial opening through the layers of the material aligned with the opening in the container.
Claim 2
Independent Claim 129 words
A method of producing a package of limp material in a cylindrical container having an opening in the side thereof comprising feeding the material into the container, producing such relative movement between the material and the container as to lay up on the interior of the container a series of figure-8 bights of the material, and maintaining such material under longitudinal compression in the direction in which it is laid during the formation of the package, rotating said container, guiding said mAterial in movement axially of the container from end to end thereof, and interrupting the relative axial movement of the material and rotation of the container atone point so as to form a radial opening through the layers of the material aligned with the opening in the container.
Claim 3
Dependent Claim 158 words
A machine for winding a flexible elongated material comprising means for holding a cylindrical container open at one end and having at least one opening substantially midway of its length, means for feeding flexible material endwise into the interior of the container through the open end, and means to produce such relative movement between the container and the material as to lay the material on the inside wall of the container in layers each comprising a series of figure-8 bights, said feeding means including means to feed the material into the container under longitudinal pressure so as to maintain the material within the container in compression exerting a force on the interior wall of the container, and means to vary the relative movement at least once in each layer to form a radial opening opposite the opening in the container to allow the inner end of the material to be drawn out through the openings for twistless payout.
Claim 4
Dependent Claim 158 words
A machine for winding a flexible elongated material comprising means for holding a cylindrical container open at one end and having at least one opening substantially midway of its length, means for feeding flexible material endwise into the interior of the container through the open end, and means to produce such relative movement between the container and the material as to lay the material on the inside wall of the container in layers each comprising a series of figure-8 bights, said feeding means including means to feed the material into the container under longitudinal pressure so as to maintain the material within the container in compression exerting a force on the interior wall of the container, and means to vary the relative movement at least once in each layer to form a radial opening opposite the opening in the container to allow the inner end of the material to be drawn out through the openings for twistless payout.
Claim 5
Dependent Claim 53 words
A machine as claimed in claim 2 for winding limp material in which said feeding means comprises a tube movable inward and outward through an open end of the container, means to reciprocate the tube, and means to supply a current of air through the tube directed towards the interior of the container.
Claim 6
Dependent Claim 25 words
A machine as claimed in claim 3, in which the tube has at least one opening therein close to but spaced from its inner end.
Claim 7
Dependent Claim 28 words
A machine as claimed in claim 2, in which the sidewall of the container is foraminated, and means for applying a suction to the outside of the sidewall.
