Further'it' willEbe noted that almost all of'such
slight amount of moisture in the printing "area
. washing ?uid as remains within the printing area
is of importance since it helps to hold the work
- piece I‘! in position during the printing operation
is removed'by a vde?nite plowing action which
avoids wetting of the clean dry margins while
and permits effective penetration of the fabric
assuring retention of a very small amount of
with the inks or colors. However, the percentage
of retained moisture must not be so great as to
moisture for promotion of the printing operation.
Any lint and ink particles which remain‘in the
printing area after 'passingrbeyond'the spraying
' cause the inks or colors to run when the work
piece is printed therewith. This rather critical
device 133 are effectively removed by‘ a de?nite
functioning of the doctor blade is assured either 10 sheering action obliquely across the blanket sur
by lateral adjustment of the tensioning roll 25,

Undue wearrof the outer surface of the blanket
in-the printing area 50 by the relatively sharp
- does‘not interfere'in any way with the feed ‘of
"a back grey between the work-piece I1 and the
edge 48 of the doctor blade pressed thereagainst
is avoided by lubrication inherently afforded by 20 backing blanket 10 as contrasted with other ma‘
chines equipped with, washing and drying ap
the washing ?uid. It has been found in practice
that the doctor blade eventually does produce
paratus which have been developed and which,
some noticeable wear in the dry- margins 49, 49
due to their characteristic constructions, prevent
the‘ready employment of a back grey.
while causing relatively little if any apparent
7' doctor blade but, preferably, is obtained by rota‘- '
wear in the printing area even after the‘ so
equipped printing machine has been used to pro
wduce millions of yards of printed fabrics. Of
course it is apparent that the wear in the‘ dry
‘margins is of no importance since these zones
of the outer surface of the blanket have no func
tion ‘in the printing operation.
Practically all textile printing plants at the
present time employ back greys indicating that
prior art proposals with regard to ‘blanket wash
ing and drying apparatus have not been entirely
satisfactory. This practice is quite generally fol
30 lowed despite the fact that the employment of
20'
7
back greys costs a printing plant thousands of
Such lint and ink or color particles, graphically
indicated in‘Fig. 5 at 60,.as may remain in the
printing area after the blanket has passed the
dollars monthly and that the cost of handling
of color which becomes dissolved in the washing
?uid, will be sheered obliquely along in the direc
art, is an unusually fast speed and it "is to'be
understood that the cleaning and'washing- ?uid
removing means of thepresent invention places
and rewashing them ‘is also very large. An ap
paratus'of the present invention equipped as de
' sprayingdevice 33 will becollected ahead of the 35 scribed above has been found to be readily and
efficiently operable at a‘printing'speed upwards
edge 48. ofthe doctor blade as indicated, at 6!
of one hundred yards per minute which, in this
and almost all'of it,‘ except possibly some amount
_ tion of the arrows to the edge of the blanket at
62 there to fall away from-the latter as indicated
in an exaggerated manner in Fig. 5 for clarity.
This action has also been observed.
‘It will thus be seen that the depositions of
inks or colors to the outer surface of the blanket '
are limited to a printing area ?anked by mar
ginal zones whichremain free from such deposi
tions and that thewashing and scrubbing are
no practical limitations on the speed at which
the machine may operate. One apparatus of the
present invention has produced more than two
million yards of printed textiles and to all’ap
pearances the backing blanket theréof'is in as
good or better condition than when this machine
was ?rst adapted to the present invention, al
though that backing blanket was not new at the s
accomplished in a manner so that approximately
only the printing area is wetted with a main- “
time the machine was provided with the cleaning
tenance of the dry ?anking margins at the
blanket edges to prevent creeping of washing
contrasted therewith,'in our experience machines
?uid to the inside surface of the'blanket thereby
avoiding any difficulties which would be attend-v
life of a blanket to about one million yards. This
ant upon such condition.
Such difficulties would "
and. drying means of the present invention. ' As
equipped with heating driers generally limit the
particular machine of. the present invention has
brought about a net saving of at least $5,000
in back greys alone, but this saving in‘ vback
