Bobbin and spool management system
A bobbin and spool management system includes a bobbin topper having a central disc with upwardly and downwardly extending stanchions projecting therefrom, each being capped with a mushroom bolster and having a medially located chamfered collar. The upwardly projecting stanchion is adapted to mate with an axial bore in the barrel of a bobbin and retain the bobbin while the downwardly projecting stanchion is adapted to penetrate the axial bore in the barrel of a supply spool and be retained on the supply spool.
1. A multi-cavity spool holder having, on a first face, a multiplicity of lower end receptacles each adapted to receive a first end of a cylindrical supply spool ranging from about 19 mm up to about 42 mm in diameter, each lower end receptacle having an upright post positioned therein adapted to enter a central throughbore in the cylindrical supply spool having a diameter of from about 6.9 mm up to about 7.8 mm whilst a second face has a plurality of dual level upper end receptacles formed therein, each upper end receptacle having an upper wall comprising a lowermost portion of one of the lower end receptacles, a shoulder being formed in each upper wall approximately 12 mm beneath an upper surface of the dual level upper end receptacle forming a bobbin receptacle adapted to receive a bobbin having an outside diameter of up to 26 mm and a height of from 8.6 up to about 12 mm and a retention portion adapted to receive a second end of the cylindrical supply spool having a diameter up to 42 mm when the bobbin is mounted upon the second end of the cylindrical supply spool using a bobbin topper interpenetrating a throughbore in the bobbin and the central throughbore in the cylindrical supply spool;
wherein the multi-cavity spool holder is comprised of a translucent polymer or a transparent polymer.
2. The multi-cavity spool holder of claim 1 , wherein the multiplicity of lower end receptacles is adapted to receive the first end of the cylindrical supply spool ranging from about 19 mm up to about 38 mm in diameter, and the retention portion is adapted to receive the second end of the cylindrical supply spool having a diameter up to 38 mm.
3. The multi-cavity spool holder of claim 2 wherein the spool holder is comprised of a polymer chosen from the group consisting of transparent polystyrene polymer and translucent polypropylene polymer.
4. The multi-cavity spool holder of claim 1 wherein the spool holder is comprised of a polymer chosen from the group consisting of transparent polystyrene polymer and translucent polypropylene polymer.
