This invention relates to an apparatus for a

is essential that it be not contaminated, and it

by the viscose process. ‘The-invention will be
therefore becomes necessary to build a machine
described with particular reference to the liquid
treatment of regenerated cellulose thread in the
form of centrifugally wound cakes. It is to be
understood, however, that the invention is equal
10 1y applicable to the liquid treatment of yarn
packages generally, regardless of the kind or
of materials which will withstand the action of
dilute acids, alkaline solutions and oxidizing
agents. ‘Materials which are satisfactorily re-’

provide improved liquid treating apparatus for
type of yarn, or the method of preparing or
winding the same.
Arti?cial threads are commonly produced from
15 viscose by extruding the latter into an acid co
treatment of packages of yarn in which that por
tion of the apparatus which must necessarily
contact the treating liquids is made of substan 15
tially chemically inert material, and the remain
ing portions of the apparatus may be constructed .
of cheaper materials which are not chemically
inert to the treating liquids, said apparatus be

bundle of ?laments formed at the spinneret
through a coagulating bath and winding the
same on or in suitable collecting devices such
ing protected against corrosion by means here?
0 as, for example, bobbins or centrifugal spinning
buckets.
The packages of yarn formed con
tain large quantities of? spinning bath liquor and
various chemical by-products of its manufacture
which must be removed'before the yarn can be
25 used in the textile'industry; The yarn packages
must furthermore be treated with bleaching an
desulfuring solutions to render the yarn suitable
for the trade.
'
'
'
It has been common practice in the past to
30 wash the cakes acid free by means of drip, pres
sure and centrifugal washing methods. The
washed cakes were then commonly subjected to
a drying procedure and thereafter the dried yarn
was reeled into skeins for‘ further puri?cation.
35 The skeins of yarn were subjected to a desulfur
ing and bleaching operation on a so-called wash
and bleach machine wherein a plurality of skeins
were hung'on a rod and ‘lafplurality of rods so
loaded with skeins carried by means of a suitable
40 progressing mechanism " under the necessary
ashowers with which the yarn‘ would be in contact
a‘ suitable length‘ of time to properly purify the
same.‘

,
Centrifugally wound bucket cakes, containing
45 large quantities of acid,_ as they come from the
spinning machines,‘ have also been'treated in a
continuous manner "by stringing them on. rods,
which are carried ‘along by 1 suitable advancing
.inechanism under drips or showers of liquids to

It is therefore an object of this invention to

It is another object of this invention to pro
vide a liquid treating apparatus for the treat
ment of yarn packages comprising yarn holding
means and yarn turning and conveying means in
which the yarn turning and conveying means is
protected from corrosion by the treating liquids.
It is a further object of this invention to pro‘
vide apparatus for ‘the liquid treatment of yarn _
packages comprising a plurality of carriages
comprised of yarn supporting means and yarn
turning ‘and conveying means, said yarn turning
and conveying means being protected from cor
rosion by‘ the treating liquids by means of indi
vidual panels or partitioning means positioned
on each carriage between saidv yarn supporting
means and said yarn turning and conveying
means, the partitions of the several carriages
interlocking with‘ each other‘ to prevent the,
escape of spray or, fumes and thereby prevent
their, contact with the yarn turning-and con‘
