Abstract
Abstract A dyestuff applicator, overlying an area of contact between a movable printing screen and a substrate, comprises a horizontal supply tube which supports an axially extending dyestuff-distributing member with freedom of relative mobility in a vertical axial plane of the tube. The bottom portion of the distributing member, forming an axially extending dyestuff outlet in the shape of a slot or a multiplicity of closely spaced apertures, is separated from its top portion, secured to the tube, by a bar-shaped body of relatively soft material which is readily compressible in the vertical direction while resisting deformation in a horizontal plane. The distributing member is weighted down by the pressure of the liquid dyestuff in a overlying space or by springs inserted between that member and the supply tube.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
135 words
In a printing machine, in combination: an apertured screen overlying a substrate to be imprinted along a contact area, said screen and said substrate being movable in a predetermined direction; a horizontal supply tube with an axis in a plane perpendicular to said predetermined direction connected to a source of dyestuff and spacedly disposed above said contact area; and a dyestuff applicator mounted on said tube and resting upon said screen, said applicator being provided with a bottom portion engaging said screen and forming an outlet along a narrow zone of said contact area centered on a vertical axial plane of said tube, said bottom portion being compressible in a vertical direction while being substantially less deformable in a horizontal plane than in said vertical direction, said outlet communicating with the interior of said tube.
Claim 2
Dependent Claim
135 words
In a printing machine, in combination: an apertured screen overlying a substrate to be imprinted along a contact area, said screen and said substrate being movable in a predetermined direction; a horizontal supply tube with an axis in a plane perpendicular to said predetermined direction connected to a source of dyestuff and spacedly disposed above said contact area; and a dyestuff applicator mounted on said tube and resting upon said screen, said applicator being provided with a bottom portion engaging said screen and forming an outlet along a narrow zone of said contact area centered on a vertical axial plane of said tube, said bottom portion being compressible in a vertical direction while being substantially less deformable in a horizontal plane than in said vertical direction, said outlet communicating with the interior of said tube.
Claim 3
Dependent Claim
20 words
The combination defined in claim 1 wherein said bottom portion is mounted with vertical bodily mobility relative to said tube.
Claim 4
Dependent Claim
31 words
The combination defined in claim 1 wherein said bottom portion is provided with an axially extending channel overlying said outlet, said channel dividing said bottom portion into two independently compressible halves.
Claim 5
Dependent Claim
24 words
The combination defined in claim 3 wherein each of said halves is provided with a multiplicity of horizontally extending bores separated from said channel.
Claim 6
Dependent Claim
33 words
The combination defined in claim 3 wherein each of said halves has an axially extending clearance flanking said channel, said clearance having a height substantially less than its width transverse to said axis.
Claim 7
Dependent Claim
18 words
The combination defined in claim 5 wherein said clearance is closed against said screen by a low-friction strip.
Claim 8
Dependent Claim
34 words
The combination defined in claim 3 wherein each of said halves is a foam-polymer bar and is provided with upper and lower reinforcing profiles overlapping each other along a vertical surface of said bar.
Claim 9
Dependent Claim
21 words
The combination defined in claim 7 wherein said reinforcing profiles are disposed along confronting sides of said bars bounding said channel.
