This cotton doubling machine was manufactured by Prince-Smith and Sells Ltd, Keighley, West Yorkshire in 1954 and is original to Masson Mills.

In a similar way to Arkwright’s waterframes which once filled all the floors of Masson Mill, the doubling frame combines the processes of drawing the cotton yarn and twisting it to give it strength. In the case of the doubling frame, two strands of thread are twisted together to give a double thickness to the final yarn.

The cotton yarn is taken off spools at the top of the machine, passed through rollers and twisted by means of a flyer onto spools or bobbins at the bottom.
