Platt Brothers' slubbing frame, 1901.

A slubbing frame is a machine used to straighten out the fibres in cotton prior to spinning. It was a secondary stage in the preparation of cotton for spinning, after it had initially pased through a drawing frame. The finer the cotton thread required, the greater the number of times the cotton was pased through slubbing frames, to make it as refined as posible. This frame was made in 1901 by the Platt Brothers of Oldham, Lancashire.
