Abstract
Abstract A device which includes a die member to apply a coating to the surface of an element of continuous length employs valve means associated with the die member to allow the coating composition to flow to the die member or to cut off the flow so that the continuous element may pass through the device in uncoated condition when desired.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
193 words
A device for applying a liquid coating composition to an element of continuous length comprising a body member including an intermediate wall having an aperture to allow passage of the element to be coated, a first axial bore in the body member in communication with and on one side of the aperture, a die member within said bore, an adjustable pressure member within said bore for engagement with the die member, a second axial bore in the body member in communication with the aperture and on the opposite side of the intermediate wall, an inlet opening in the body member to allow a coating composition to be fed to the second bore, and valve means within said second bore for regulating the flow of coating composition to the die member, the valve means comprising an annular wall extending axially from said intermediate wall into said second bore and surrounding said aperture, the free edge of the annular wall providing a valve element, and an adjustable valve member in the second bore cooperable with said valve element, the die member, adjustable pressure member and valve member having openings therethrough in alignment with said aperture.
Claim 2
Independent Claim
193 words
A device for applying a liquid coating composition to an element of continuous length comprising a body member including an intermediate wall having an aperture to allow passage of the element to be coated, a first axial bore in the body member in communication with and on one side of the aperture, a die member within said bore, an adjustable pressure member within said bore for engagement with the die member, a second axial bore in the body member in communication with the aperture and on the opposite side of the intermediate wall, an inlet opening in the body member to allow a coating composition to be fed to the second bore, and valve means within said second bore for regulating the flow of coating composition to the die member, the valve means comprising an annular wall extending axially from said intermediate wall into said second bore and surrounding said aperture, the free edge of the annular wall providing a valve element, and an adjustable valve member in the second bore cooperable with said valve element, the die member, adjustable pressure member and valve member having openings therethrough in alignment with said aperture.
Claim 3
Dependent Claim
22 words
A device according to claim 1, wherein the second axial bore is defined by a circumferential wall, said inlet opening extending therethrough.
Claim 4
Dependent Claim
47 words
A device according to claim 1, wherein the die member is frusto-conical, of elastomeric material and has a central opening, and the wall of the body member defining the first bore at the area adjacent the frusto-conical member is matingly contoured, the wall converging toward said aperture.
Claim 5
Dependent Claim
74 words
A device according to claim 3, wherein the wall of the body member defining the first bore adjacent the converging area is of substantially constant diameter and internally threaded, and the adjustable pressure member is matingly threaded, the pressure member being engageable with the side of the frusto-conical die member having the larger diameter to apply pressure in an axial direction to thereby control the size of the central opening-extending through the die member.
Claim 6
Dependent Claim
23 words
A device according to claim 1, wherein the adjustable pressure member is provided with means cooperable with a tool for rotating the member.
Claim 7
Dependent Claim
55 words
A device according to claim 1, wherein the free edge of said annular wall is beveled to provide a valve seat and the adjustable valve member is provided with a mating bevel whereby the pressure engagement of the beveled surfaces will prevent the flow of coating composition to the aperture and to the die member.
Claim 8
Dependent Claim
32 words
A device according to claim 6, wherein the adjustable valve member is extErnally threaded, and a portion of the internal surface of the circumferential wall defining the second bore is matingly threaded.
Claim 9
Dependent Claim
23 words
A device according to claim 7, wherein the adjustable valve member is provided with means cooperable with a tool for rotating the member.
Claim 10
Dependent Claim
29 words
A device according to claim 7, wherein the adjustable pressure member and the adjustable valve member are each provided with means cooperable with a tool for rotating the members.
