This invention relates to the manufacture of
threads of synthetic origin, and is more particu
larly concerned with a process and apparatus
for the continuous manufacture of wet spun
threads.
Continuous spinning as the name implies, com
prises the introduction of a hydrated colloid into
a spin bath to form a thread, the after-treatment
0f successive portions of the freshly formed
`thread while it is moving from the spin bath to
a point of collection and the collection of the
completely finished thread into a commercially
salable package. The very nature of continuous

handling of the thread during these periods is of
extreme importance and demands the exercise of
unusual precautions to avoid loss of time and `í
waste of materials.
One of the objects of this invention is to reduce
to a minimum the time required for the transfer
of the thread from one element of the machine
to another and hence avoid any more loss of pro
duction than is absolutely necessary for the
transfer.
Another object is to properly support the
thread at all times, i. e., during the threading
