~; This invention relates to the supply, feeding and stag-
ing and in particular instances overlapping of narrow fluid
bands in variable individual and in variable total width
comprising an infinite number of combinations and variations
and means to guide these generally narrow fluid bands in a
controlled and reliable manner to an application plane where
they are adhering to and removed by one continuously or inter-
mittently moving surface representing a substrate or a
carrier.
One object of this invention is to provide means and app-
aratus for multiple fluid feeding to be applied to a moving
surface either stretched between a number of rollers or
carried with the assistance of an elastic blanket, or directly
: to a transfer medium with means or patterns for additional
105~7S0
modifications of the fluid deposits.
Another object of this improvement provides means for
efficient and inexpensive patterning of a multitude of
generally narrow fluid bands in a manner which prevents
boundary interference and friction from influencing the
ready and unimpaired feeding of the multiple liquid streams
to the application plane.
It is a special object of this invention to permit
overlap of two or more liquids within the same design loca-
tion on the application plane producing a continuous overlay
of several narrow fluid bands according to the predetermined
design on the surface being moved across the application
plane of the pinstripe system.

Another object is the formation of staging chambers with dividers
such as ribs and bridges serving also as sealing supports of the pinstrip
during operation and adjustable means for perfectly even s-tretching of the
laterally extending pin-strip across the supporting elements.
It is a further object of this invention to assure the smooth passage
of the substrate in front of the pin-strip by recessing part of the small
liquid orifices in a way to prevent the passing area of the substrate from
getting caught, snagged or abraded in any conceivable way.
Other objects of the invention will in part be obvious and will in
part appear hereinafter. The invention accordingly comprises the process
involving the seve-ral steps and the relation and order of one or more such
steps with respect to each of the others and the apparatus possessing the
construction, combination of elements and arrangement of parts which are
examplified in the following detailed disclosure, and the scope of the
inventionl which will be indicated in the claims.
; For a fuller understanding of the nature and objects of this invention,
reference should be had to the following drawings illustrating simple forms
of the pinstripe application system. It must be understood that the infinite
variety of possible combinations under these improvements cannot be dis-
~ played exhaustively and that the drawings are merely illustrations of one
i single modus of patterning which anyone acquainted with the art may vary
without leaving the scope of this invention. ~ith these and other objects
in view, which will become apparent in the following detailed description,
the present invention will be clearly understood in connection with the
accompanying drawings in which :
Figure 1 is a partial side elevation of the pinstriping arrangement
in combination with a diagrammatic depiction of the passing substrate
and the supporting roller.
Figure 2 is a partial front elevation of the left section of the
pin-stripe arrangement showing the pressure adjustment omitted for
clarity considerations in figure 1.
Figure 3 is a diagrammatic view of the diagonal cross-channeling
- in the application plane with a pattern strip,- or pin-strip,- in place
and examples of patterning orifices.

strate the connection between main supply, bore connector and staging area.
Figures 5a and 5b are schematic side and plan views respectively,
to show one example of recessed orifices,- the arrow illustrates the
direction and position of the substrate in relation to the orifices.
The principal body of the pinstripe applicator is composed of
numerous feeder chambers 1 to supply diversified liquids which are physi-
cally separated from each other feeder and each is filled or replenished
- 3 - 105975
through one or more supply ;openings 2 with a capability of one or more
liquid components in each feeder 1. Openings 2 are conveniently loca-ted at
an area designed as the upper side at any particular modus of application.
~his area will be structurally modified according to varying demands on
actions and locations of the pin-stripe-applicator. The position shown in
figs. 1 and 2 iS almost vertical but the pin-stripe-applicator functions
equally effec-tive a-t any other angle going even beyond the horizontal axis
as long as enough fluid pressure is present to ensure the constant refurbi-
shing of liquid into the staging area 3.
The feeder chamber 1 is connected to the staging area 3 with the
open bore 5 which is optionally pierced by the valve rod 6 penetrating all
bores 5 simultaneously and having a multitude of valve orifices at distances
equal to the bores 5 with the ability to partially open, fully open, or close
all bore-5-connections to the staging area at the same instance. For acti-
vating purposes a lever is attached to one or both extremities of the valve
rod and a turn of ninety degrees accomplishes opening or closing. The dia-
meter of bore 5 is small enough to permit the conversion from the wider cross-
section of feeder 1 to the narrower rhomboidal staging area 3. The area 3
is capable to carry an increasing number of overlapping positi~s- the more
the angle deviates from the vertical borderline to the near hori~ontal.
Figure 3 illustrates one 45Q position of the diagonal ribs 20D
The pin-stripe-applicator generally comprises the feeder chambers 1,
the staging area 3 and the pin-strip 4 and is held in operating position and
guided by -the two collars 7 and 8. Collar 7 has a shaft extension 9 on both
lateral extremities, but shown only as section of the left half. The shaft
extension 9 is used to receive and apply adjustable pressure of the entire
pin-stripe-applicator against the substrate 10 or a carrier or both in c~n-
junction. The direction of the movement is either in the sense of the arrow
or 180 degrees in reverse.
Figure 2 shows the pressure arrangement with the collar of the plun-
ger 11 being pushed forward by the coil spring 12 which is adjustably depres-
sed by the screw 13 and acts on the shaft 9 being attached to the collar 7
which holds the pin-stripe-applicator. This arrangement of two plungers 11
at both lateral extremities will hold the applicator against the substrate
with just enough adjusted pressure to form a continuous hollow depression
to fit and pass around the pin-strip 4. It is obvious that this pressure
adjustment may be carried out by any other pneumatic, hydraulic, or
mechanical set-up within the meaning of this improvementO
To regulate kinetic energy of fluid supply and to put the curve of
the pin-strip 4 into the desired position in regard to the roller 14 the rod
15 on collar 8 permits an angle adjustment without losing r~gidity.The angle

I of the two nuts 18 and 19. During this movement the bolt 16 slides in the
pivoting cube 17. The two forces acting downward or forward on collar 7 and
in angular direction on collar 8 provide all necessary guidanca to bring and
hold the pin-stripe-applicator in the most favourable production position.
The pin-strip 4 has to be stret~hed tightly across the diagonal ribs
20 of staging area 3. To this purpose one lateral se,lva;~e of pinstrip 4 is
¦ perforated at short intervalls to be hooked into the equidistant pins 21
positioned laterally along one side of the pin-stripe-applicator. The opposite
selvage of the pin-strip 4 is equally perforated to engage the fitting pins
of bar 22 which is threaded at convenient distances for the insertion of
scréws 23 turning freely in bores 24 going through collar 7. Tightening the
screws 23 will pull the bar 22 upward and proceed un-til the equally upward
moving pins completed stretching the pin-strip 4 into sealing position con-
tacting the diagonal ribs 20 as they present in their totality a curved sur-
face. For more efficient sealing the ribs 20 are optionally covered with a
resilient sealant and/or the pin-strip 4 has a layer of elastic material
affixed to it to facilitate sealing at all points of contact.
The pin-strip 4 is perforated for selective passage of decorating or
acting liquids along its lateral extension and across a large part of its
width withiorifi:ces 25 designed to release a narrow flow of liquids of the
type emanating from the staging area 3 right behind it. ~he diminutive cross-
section of the pin-strip 4,- it is sheet material of one type or another,-
obviates boundary interference in laminar flow and makes it feasible to re-
lease even liquids with relative high viscosity at considerable speeds of
production~
The staging area 3 is oriented at an angle best capable to serve spe-
cific pattern notations. The angle of forty-five deg~ees depicted in figure
3 is an average mean of the possibilities. The section A-B in figure 3 para-
lells the direction of passage of any substrate or carrier 10,- movement is
,either up or down. The section A-B traverses four pattern orifices 25 in the
second staging area 3, none in the third, and one more orifice in the fourth
staging area. A substrate passing in the direction of this section A-B,-
going downward for example,- would pick up in passing four fluid contacts
,out of the second area 3 and on top of this would take on the last fluid
.of one orifice from the fourth area 3. To the left of this fall-,on of one
~orifice in the fourth area will be deposited,~ive outlets and~four^ additio-
nal ones to the righ-t. Going up diagonally to the right in the fourth area 3
there are twelve more outlet orifices 25 just below center and twelve more
orifices higher up to the right. In relation to the passing substrate all
three horizontal orifice lines join to produce a liquid deposit of a width
correspon ing to the total width of all three 1ines but inter~persed and
10597S0
added on by more deposits coming from clusters of orifices 25 in the third
and fifth area ~liAs your eye proceeds more examples of orifice combinations
are illustrated without being able to show fully all the millions of possi-
bilities feasible to a knowledgable designer.
me number of staging areas possible to overlap through orifices falling
into the same vertical line increases with inclining of ribs 20 towards the
hori~ontal and decreases as the ribs 20 approach vertical orientation.
me orifices itself come in differen-t shapes complying to specific
exigencies of design and/or substrate, their shapes being either round, or
square and other combinations of these basic forms, combinations in shape
and/or size. An important feature of these orifices 25 is the recession of
the part of each orifice confronting the location of exit of the substrate
as it passes. mis recession is illustrated in figures ~a and 5b and the
direction and location of the substrate is indicated by arrow. This recession
of each orifice 25 assures the efficient and continuous operation during
production without clogging the orifices or abrading the substrate. This
recession makes the operation self-cleaning and assists in releaæing the
liquid flow into the direction of operation by lessening of the forces of
liquid shearing. It also increases the cohesion / adhesion element of this
arrangement.
The pin-stripe-application-system is able to cover the entire width of
the substrate or carrier completely or any selective part thereof. It is also
capable to form a highly spec~ized part in combination with one or more
printing and application media, such as for example wide-striping, roller
printing, rotary screen printing, bar printing, spray applications, pad-
dyeing, etc. Some or all of these may be combined to form entirely new
types of machines for novel expressions in surface decorating. The pin-stripe-
application-system contributes another valuable specialty to surface deco-
rating together with high economy of operation and simplicity of change of
designs and patterns.
