larly concerned with a process and apparatus for
the continuous manufacture of Wet> spun threads.
Continuous spinning., as the name ` implies,
comprises the introduction of a, hydrated colloid
into a spin bath to form a thread the after-treat
ment of successive portions of the freshly formed
thread While it is moving from the spin hathl to a
point of collection and the» collection of the com
pletel’y ñnished thread into a commercially sale
VThe very nature of continuous operation ren
ders the handling of the thread, for instance
fromone treating unit to another or during the
exchange of. an empty bobbin for a full one,
extremely diiiicult. :Def-t and accurate handling
of the thread during these periods is of extreme
importance and demands the exercise of unusual
precautions to avoid loss `of time and waste of
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-v 25
duction than is absolutely necessary for the
This invention relates to the manufacture of
threads of synthetic origin„and is more particu
able package.
Another Yoloject is to properly support the
thread at all times, i. e., during the threading-up
of» the machine or'during the exchange of a full
bohbin for an empty one and hence facilitate the
handling ofthe thread during such periods so. as
to avoid undue Waste.

" Inasmuch as roller 45 does not extend in atruly
horizontal direction, it is evident that this roller
will, when properly disposed with respect to roller
46,’ cause thread wound in a coil around the two
rollers to move axially of the unit. The theory
of _operation of two-roller thread-storage, thread
advancing units is the familiar one that thread
drawn onto a roller will approach the same at a
right angle to the direction ofjpull which is, of
course, from the axis thereof. Thus, if roller 45
is slightly inclined with respect to the horizontal
so that thelaxis thereof and that of roller 46
converge in the direction of their unsupported
ends, thread wound around the two rollers will
necessarily progress in the direction of con-vergence, i. e., toward the unsupported end of the
unit. Since the spacing between adjacent con
nected coils is a function of the angle of con
` vergence, it is also evident that the angle will
determine the number of coils in unit II at any
given vtime which», in turn, will control the dura
tion of any treatment they may receive wduring

of the small cylinder 'Il constituting the tem

speed of bodily movement of the temporary col

this way, the occurrence of slack is avoided while
