A 1929 article by engineer E. Toenniessen describing two devices for speeding up doffing (changing full bobbins or tubes) on cotton spinning and doubling frames: a press-on wheel that seats empty tubes on all spindles of a frame side in seconds, and a press-off fork carriage that lifts 20 to 25 tubes at once. It explains the problems of loose tubes slipping, the drawbacks of pressing them by stick or by hand, and the time savings found in mill trials. Two line drawings and two photographs illustrate the devices, and a recommended doffing procedure is given.
