There is an extensive list of finishing processes in wool production for both worsted and woollen fabrics. Fulling is the immersion and pounding of fabric to make the fibres interlock. Crabbing permanently sets this interlock. Decanting shrink-proofs the fabric. Dyeing changes the fabrics colour. This large Fulling Machine is a distinctive item related to this phase of cloth production. Made by J. Dyson and Sons in Geelong, this Fulling Machine completes all the above steps, except dyeing, with a combination of hot water, soap and friction. Before the invention of such a machine, all these processes had to be completed individually.
