Bobbin winding system

Abstract

A bobbin winding system embodying an apparatus and method for simultaneously winding two separate bobbins independent of a sewing machine is provided. The apparatus may include a bobbin winder having a thread tree and two independent bobbin sets. Each bobbin set may provide a spindle, a spindle disc, a tension guide and a bobbin bumper. For each bobbin set, a user may removably secure a spool of strand on the spindle, wherein the strand is threaded to a bobbin removably secure to the bobbin bumper. Whereby each strand may be received by at least one guide loop of the thread tree, then received by the tension guide and then secured by the bobbin of the bobbin set. The user may adjust the height of each spool by adapting the relevant spindle disc. The bobbin winder may then separately rotate each bobbin bumper so as to pull strand from at least a portion of each spool to wind around the bobbins. The bobbin winding system provides a method of winding the bobbins independent of a sewing machine whereby the interruption to the underlying sewing project is minimized, especially for multi-colored fabrics and projects.

What is claimed is: 
     
         1 . A double bobbin winder comprising:
 a body forming an internal containment space for housing two motors;   two spindles rotatably connected to an external portion of the body;   a telescopic thread tree connect to the external portion of the body, wherein the tree provides two branches of guide loops, each branch extending in the direction of each spindle; and   two bobbin bumpers for removably securing a bobbin, each bobbin bumper disposed on the external portion of the body, and wherein each bobbin bumper is rotatably connected to one of the two motors so as to selectively and independently receive rotational torque from the respective motor.   
     
     
         2 . The double bobbin winder of  claim 1 , further comprising a spindle disc operatively connected to each spindle, wherein each spindle disc is configured to adjust the height of each spindle relative to the external portion of the body. 
     
     
         3 . The double bobbin winder of  claim 2 , further comprising two tension guides disposed on the external portion of the body between the two spindles and the two bobbin bumpers, each tension guide configured to apply tension to a received strand 
     
     
         4 . The double bobbin winder of  claim 3 , wherein the body is formed in part by a upwardly facing wall and a front side,
 wherein the upwardly facing wall provides the two spindles, the two spindle discs and the thread tree, and   wherein the front side provides the two bobbin bumpers.   
     
     
         5 . A system for simultaneously winding two separate bobbins independent of a sewing machine utilizing a double bobbin winder of  claim 1 , comprising:
 two bobbins, each operatively engaged by each bobbin bumper; and   a first spool of a first strand received by one of the two spindles,   wherein the first strand is received through one of the two branches of guide loops, terminating in a removably secure connection to one of the two separate bobbins.   
     
     
         6 . The system of  claim 5 , further providing a second spool of a second strand received by the other of the two spindles, wherein the second strand is received through the other of the two branches of guide loops, terminating in a removably secure connection to the other of the two separate bobbins. 
     
     
         7 . The system of  claim 6 , wherein the first strand is a first color and wherein the second strand is a second color. 
     
     
         8 . The system of  claim 6 , wherein the first strand is a first fabric and wherein the second strand is a second fabric. 
     
     
         9 . A system for simultaneously winding two separate bobbins independent of a sewing machine utilizing a double bobbin winder of  claim 3 , comprising:
 two bobbins, each operatively engaged by each bobbin bumper;   a first spool of a first strand received by one of the two spindles; and   a second spool of a second strand received by the other of the two spindles,   wherein the first strand is received through one of the two branches of guide loops, and then through one of the two tension guides, terminating in a removably secure connection to one of the two separate bobbins, and   wherein the second strand is received through the other of the two branches of guide loops, and then through the other of the two tension guides, terminating in a removably secure connection to the other of the two separate bobbins.   
     
     
         10 . The system of  claim 9 , wherein the first strand is a first color and wherein the second strand is a second color. 
     
     
         11 . The system of  claim 9 , wherein the first strand is a first fabric and wherein the second strand is a second fabric.
