Abstract
The purpose of this invention is to change the direction of the feed so that the user/operator can now use the free arm of the sewing machine to the optimum advantage. The conventional domestic free arm sewing machine has, heretofore, been limited to sewing in a lateral direction across the free arm. The use of this invention allows the machine to be used so that tubular shaped garments can travel along and around the free arm of the sewing machine this sewing can be accomplished with any outside seams, something, heretofore, impossible with a conventional free arm sewing machine.
