A few more explanations (specially for Joe):

rag 'ole dust; I suspect this is a reference to the willy 'ole (see below) but I am unsure.

piece makes the menders grieve; a piece being a woven length of cloth, it then gets passed to burlers & menders for finishing work (very skilled work, and taxing on the eyesight). A piece which makes the menders grieve is presumably one with a high number of faults needing repair.

Traps; IIRC when the weft snags in the flying shuttle rather than paying out smoothly; gives rise to stopping and weaving faults, so more work for the menders and poorer quality product (hence lower price too)

Morley made a lot of shoddy, so there was a high incidence of willy 'oles and their inhabitants the willyers (aka willy 'ole lads, see separate thread) They were among the lower ranks of mill workers, producing cheap stuff to be spun into warps from a mixture of recycled rags and oil for the weaving of shoddy. The little that couldn't be reused in cloth ended up in nearby fields fertilising rhubarb.

Roll a few woods; play a game or two of bowls Bowls the game - wikipedia
