fabricating machines.
The spinning machine comprises a plurality of
spindles having bobbing mounted thereon, the
bobbins upon which the rayon is wound before it
is twisted being below the line of bobbins which
receive the rayon after it has been properly ten
sioned and twisted.
When the spinning machine is in motion, the
yarn running from the delivery bobbin to the
take-up bobbin is tensioned resulting in stretched
yarn and broken ends due to the high tension. If
the stretched yarn and broken lilament yarn are
