Scrap winder

A scrap winder for use with a slitting machine, said slitting machine having an uncoiling portion, a slitting portion, and a recoiling portion, said slitting machine adapted to generate a strip of edge trim, said scrap winder having:

• a pivoting frame pivotable between a release position and a winding position, said pivoting frame having a mandrel rotatably affixed thereto and rotatable about a mandrel axis;
• a sliding hub axially moveable between an extended position and a retracted position on a driveshaft along a driving axis, said sliding hub fixed from rotation with respect to said driveshaft, said sliding hub having a front face, said retracted position defined by said front face being at a relatively large distance from said mandrel, said extended position defined by said front face relatively close to said mandrel, said sliding hub having a puller cable reel portion consisting of a sheave on said sliding hub located adjacent said front face, said puller cable reel portion is outward of said mandrel facing surface when said sliding hub is in said extended position, said front face adapted to receive a distal end of said strip of edge trim;
• a yoke having a sliding hub mating portion mated with said sliding hub for shifting said sliding hub axially between its said extended position and retracted position;
• and
• a cable affixed at one terminal end to said puller cable reel portion, said cable having a retrieving end at another terminal end, said retrieving end adapted to affix a start end of said edge trim;
• and
• when said pivoting frame is in said winding position, said mandrel is located at a relatively close position to said sliding hub.

A scrap winder for use with a slitting machine, said slitting machine having an uncoiling portion, a slitting portion, and a recoiling portion, said slitting machine adapted to generate a strip of edge trim, said scrap winder having:

• a mandrel moveable between a release position and a winding position, said mandrel rotatable about a mandrel axis and tapered along its length;
• an inboard plate having a center aperture and fixed from rotation with respect to a driveshaft rotatable about a driving axis, said inboard plate having a mandrel facing surface and a yoke facing surface;
• a sliding hub fixed from rotation with respect to said driveshaft and axially moveable along said driving axis through said center aperture between an extended position and a retracted position, said sliding hub having a front face, said refracted position defined by said front face being at a relatively close distance to said mandrel facing surface, said extended position defined by said front face extending outward from said mandrel facing surface, said sliding hub having a puller cable reel portion consisting of a sheave on said sliding hub located opposite said front face, said puller cable reel portion is outward of said mandrel facing surface when said sliding hub is in said extended position, said front face having a protrusion adapted to receive a distal end of said strip of edge trim;
• a yoke having a sliding hub mating portion mated with said sliding hub for shifting said sliding hub between said extended position and retracted position;
• and
• when said mandrel is in said winding position, said mandrel located at a relatively close position to said sliding hub and said mandrel axis substantially coaxial to said driving axis.
