Dobby Loom Setup and Style Change Procedures
topic
Dobby loom style changes require warp change through tying or drawing-in when the threading changes, reed change for different thread counts, heddle replacement when shaft loading changes, and dobby programme download for the new pattern, with electronic dobby reducing style change time from the hours required for mechanical chain changes to the minutes of software programme transfer, enabling economically viable production of shorter fabric batches for fashion markets requiring frequent style rotation.
Role
Determines the economic batch size for dobby fabric production by governing the total warp change and style change downtime that must be amortised across the production run, with electronic dobby programme change being the element that most significantly reduced dobby style change time compared to earlier mechanical dobby systems, enabling the batch size reductions that have made dobby weaving economically viable for the shorter production runs of modern fashion fabric markets.
