Abstract

Abstract An apparatus for supplying liquid to a printing roller or the like, for example, liquid dye, in which at least one body extending axially of the roller to be supplied is provided with passage means distributed therein in the direction of the length of the roller and adapted for adjustment as to effective cross sectional area thereby to control the liquid supply to the roller. Preferably, a plurality of such bodies are arranged in end to end relation along the roller and each passage and each body supplies a certain axial region of the periphery of the roller.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 251 words
An apparatus for the controlled dispensing of a liquid medium, such as dye, to a roller in a printing machine and comprising in combination: body means extending axially of the roller and adjacent the periphery thereof, liquid supply means connected to said body means on the side facing away from the roller, passage means extending through said body means to the side facing said roller to convey said liquid from said supply means to said roller, adjustable gap opening means carried by said body means adjacent said roller and including means for adjusting the effective area of the passage means, said adjustable gap opening means comprising a pair of bar elements parallel to and extending in the axial direction of said roller and relatively adjustable to adjust the effective area of said passage means, said bar elements being in superimposed relation to each other in the direction of flow in said passage means and said passage means being in the form of bores in said bar elements, said bar elements being relatively adjustable in the direction of the length of said roller to vary the degree of registration of said bores, said body means being concave on the side adjacent the roller so as to fit closely about a portion of the circumference of said roller, and a fabric cover on the body means covering said concave roller side and having the properties of conducting liquid from the passage means to said roller and of wiping the surface of said roller.
Claim 2
Independent Claim 251 words
An apparatus for the controlled dispensing of a liquid medium, such as dye, to a roller in a printing machine and comprising in combination: body means extending axially of the roller and adjacent the periphery thereof, liquid supply means connected to said body means on the side facing away from the roller, passage means extending through said body means to the side facing said roller to convey said liquid from said supply means to said roller, adjustable gap opening means carried by said body means adjacent said roller and including means for adjusting the effective area of the passage means, said adjustable gap opening means comprising a pair of bar elements parallel to and extending in the axial direction of said roller and relatively adjustable to adjust the effective area of said passage means, said bar elements being in superimposed relation to each other in the direction of flow in said passage means and said passage means being in the form of bores in said bar elements, said bar elements being relatively adjustable in the direction of the length of said roller to vary the degree of registration of said bores, said body means being concave on the side adjacent the roller so as to fit closely about a portion of the circumference of said roller, and a fabric cover on the body means covering said concave roller side and having the properties of conducting liquid from the passage means to said roller and of wiping the surface of said roller.
Claim 3
Dependent Claim 44 words
An apparatus in combination according to claim 1 in which said passage means comprises a plurality of passages distributed in the axial direction of said roller, and bores at the end of said passages adjoining said roller being arranged in circumferentially spaced axial rows.
Claim 4
Dependent Claim 37 words
An apparatus in combination according to claim 2 in which said body means includes recess means communicating on one side with a respective passage and on the other side with the said bores pertaining to the passage.
Claim 5
Dependent Claim 29 words
An apparatus in combination according to claim 2 in which the bores in each said row of bores are staggered when viewed in the radial direction of said roller.
