This is the Silver Needles Cardboard Electric Cone Winder - the SN100. See more on this winder on the YARN WINDERS page.
This winder uses witch hat style cardboard cones while the newer SN200 uses open top cones.
My current winder is missing the “knot detector” wire piece that mounts onto the power switch - which when used correctly will turn off the machine if there’s a knot hopefully. When I use this Winder, I usually hand tension or the cone comes out floppy.
