Doff
Doff turns up in 2 fields: nonwovens, textiles. Here is what it means to the people in each one.
Doff in nonwovens
To take a finished roll off a winder and start winding on a fresh core or shaft.
On the line winder, a doff transfers the web to a new shaft, cuts it and takes the full mother roll off, ideally without slowing the line. On slitters, doffing means unloading the full set of slit rolls. Fast, clean doffs cut waste and wrinkles at the start of each roll.
"Doff the winder at 6,000 meters, then walk the roll over to the slitter."
Doff in textiles
To remove full bobbins, cones, or processed fiber from a spinning frame or carding machine.
Doffing is the mechanical or manual process of stripping accumulated textile fibers from a machine. In spinning, it means taking off the full bobbins of spun yarn and replacing them with empty ones so the machine can continue running. In carding, it refers to the removal of the combed fiber web from the main cylinder using a smaller doffer cylinder. It is a critical, time-sensitive step in mill production to keep machinery operating continuously.
"Stop the ring frame, we need to doff these bobbins before the yarn backs up."
