Hand bobbin winders are available in single-end and double-end models. The single-end winder has a tapered shaft that will accommodate bobbins up to 6″ long. The double-end winders can be used for bobbins, pirns, and large-flanged spools up to 9″ long and 5-1/2″ in diameter. A clamp incorporated into the base means you’ll never have to hunt around for a “C” clamp again. They are belt-driven with self-lubricating bronze bearings.
Electric bobbin winder is double-ended and will accommodate bobbins, spools, and pirns up to 9″ long and with flanges up to 4″ in diameter. An electric winder saves time, especially when there’s a lot of winding to do. The speed of the winder is controlled by a foot-powered rheostat like that of a sewing machine.
