US 4,111,376 A · Continuous strand winding apparatus

Abstract

Winding apparatus for the continuous winding of an advancing strand, having two coaxially mounted, spaced and independently driven, removable reels and a traverse mechanism for delivering strand to the reels alternately. Each of these reels is mounted on an axle which is equipped with a machine reel and snagger means assembly which is a permanent part of the machine and each of them are mounted adjacent to the remote ends of said reels when said reels are in winding position so that the reels are disposed for rotation about a common axis between the machine reels and snagger means assembly. The traverse means is controlled so as to distribute the strand onto one of the reels until a predetermined length of strand is wound thereon. Further means is provided for rapidly moving the traverse means across the empty reel into a position for directing the strand onto the machine reel associated with the empty reel. Means are also provided to restrain the strand while said traverse means is moving across the empty spool into position to wind on the machine reel. Once the traverse means is in position to wind on the other machine reel, the restraining means are removed and the strand is brought into contact with the snagger for the empty reel. After at least one revolution of the strand is wound onto the machine reel, cutter means is actuated to cut said strand adjacent to the snagger means but between the snagger means and the filled reel. This operation is controlled by a device that counts a predetermined number of revolutions. A second device is also utilized to count a second predetermined number of revolutions greater than the first so that a predetermined number of revolutions of the strand will be wound on the machine reel. After this second predetermined number of revolutions have been attained, the traverse means is moved into normal winding position on the empty reel and normal winding thereon is continued until that reel is filled.

Dependent claims

Winding apparatus for the continuous winding of an advancing strand comprising:

(a) a pair of co-axially mounted, spaced, independently driven, and removable reels;
(b) a pair of machine reels mounted for rotation with said reels about a common axis, one of said machine reels is mounted adjacent the remote end of one of said reels and the other is mounted adjacent the remote end of the other of said reels;
(c) snagger means disposed between the remote end of each of said reels and its associated machine reel and mounted for rotation with said machine reel;
(d) means for traversing strand onto one of said reels until a predetermined length of strand has been wound thereon;
(e) restraining means for temporarily restraining the strand and maintaining it in a winding relationship with the filled reel;
(f) means for rapidly moving the traverse means across the other reel into a position to direct said strand onto the machine reel associated with said other reel;
(g) means for withdrawing the restraining means thereby permitting the restrained strand to change its path to a path which intersects the path of the snagger means;
(h) means for severing the strand between the snagger and the filled reel after at least one revolution of strand has been wound onto the machine reel;
and
(i) means for moving the traverse means into normal traversing relation with the other reel after a predetermined number of revolutions of strand has been wound onto said machine reel.

Winding apparatus for the continuous winding of an advancing strand comprising:

(a) a pair of co-axially mounted, spaced, independently driven, and removable reels;
(b) strand traverse means for alternately distributing strand to each of said reels;
(c) a pair of machine reels mounted for rotation with said reels about a common axis, one of which is mounted adjacent the remote end of one of said reels so that said reels are disposed for rotation about said common axis between said machine reels;
(d) snagger means disposed between the remote end of each of said reels and its machine reel;
(e) traverse means for distributing said strand onto one of said reels until a predetermined amount of strand is wound thereon;
(f) means for restraining said strand disposed adjacent the adjacent ends of said reels and adapted to move into a position to intercept said strand when said strand moves past the adjacent end of the reel being filled and to continue to guide said strand onto said filled reel;
(g) means for rapidly moving said traverse means across the empty reel into a position to deliver strand to the machine reel associated therewith;
(h) cutter means adjacent the remote end of each of said reels and adapted to sever said strand near the snagger associated with said reel;
and
(i) control means comprising:
(1) means for moving said restraining means into strand interception position when a predetermined length of strand has been wound on a reel;
(2) means for activating the means for moving the traverse means to the machine reel associated with the other reel;
(3) means for withdrawing the restraining means;
(4) means for activating the cutter means after a first predetermined number of revolutions of strand has been wound onto the machine reel;
and
(5) means for moving the traverse means into normal winding position after a second predetermined number of revolutions of strand, in excess of said first predetermined number, has been wound onto said machine reel.
