The staircase has art deco spindles with plain acorn top.
The spinning or throwing which follows is done on a frame with upright spindles and flyers, the yarn as it is twisted being drawn forward through guides and wound on revolving bobbins with a reciprocating motion.
This is a frame built with forty or more spindles.
The number of mills has decreased, but machinery now runs so much more quickly than formerly that more yarn is being spun on fewer spindles.
A great amount of doubled and trebled yarn is now sold, though it does not appear that recent expansions have added much to doubling spindles, and considerable developments continue in the use of dyed and mercerized yarns.
