sufficient pressure against the side walls of a wide trough
to prevent the continued passage of the sliver. In any
event these crepe ends do not remain properly positioned
in the sliver to form the desired slubs. The tube con
fines the crepe slubs to the sliver bundle to produce a
satisfactory spun yarn even when the'crepe yarn is of
relatively heavy denier.
It is to be understood that a machine of this type
consists of a plurality of the drafting and breaking places
described arranged to form a double sided machine. The
roll pressures at all places on the machine are the same
because the pressure is applied through the common mani
folds.
While Iv have described this invention in detail with
respect to certain embodiments thereof, it is not desired
to limit it to the details described and illustrated except
insofar as they are set forth in the following claims.
