Abstract

Abstract A means for controlling the position and location of a stationary transversal member (12) acting on the web in a paper machine. By the means is adjusted the distance (H) of said member (12) from the web and/or its position (a) around its axis. The control means at the same time gives support to the frame member (10) of said member (12) at both ends against the frame structures (41) of the paper machine. The control means comprises on both ends of the frame of the stationary member (12) acting on the web, a slide member structure comprising a first slide member (17), a second slide member (31) and an intermediate slide member (22), which connects with each other the first and second slide members (17, 31). The frame part of said member (12) finds support on the first slide member (17), and the second slide member (31) rests on the frame structures (41) of the paper machine. Two slide members (17,22,31) have opposed curved sliding surfaces (20), of which the centre-of-curvature axis coincides with the straight line defined by the tip edge (12') of said member (12). On the other hand, two of the slide members (17, 22, 31) have sliding surfaces (30) which are straight in their direction of movement. The means furthermore comprises control members (18, 19, 23, 26, 27, 32), by the aid of which on one hand by displacing with reference to each other one slide member and the intermediate slide member (22) along the curved sliding surface (20) the angular position (α) of the member is adjusted and on the other hand by displacing with reference to each other the intermediate slide member (22) and the other slide member along the straight sliding surface (30) the distance (H) of the member from the web is rectilinearly adjusted independent of the angular position adjustment.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 333 words
Means for controlling the position and location of a stationary member (12), used in a paper machine, acting on the web that is being manufactured and transversal with reference to the direction of travel of the web, by which means the distance (H) of said member (12) from the web and/or the position (a) of said member around its axis is controlled, and the body part of said member (12) being by mediation of this control means carried by both ends on the frame structures (41) of the paper machine, characterized in that the control means comprises on both ends of the frame of the stationary member (12) acting on the web a slide member structure comprising:- - a first slide member (17), on which the frame part (10) of said member (12) finds support; - a second slide member (31) supported by the frame part (41) of the paper machine; and - an intermediate slide member (22), connecting the first and second slide members (17,31); in that two of said slide members (17,22,31) present, acting against each other, sliding surfaces (20) shaped to represent part of a cylinder surface and their centre-of-curvature axis coinciding with the straight line defined by the tip edge (12') of said stationary member (12) or being immediately adjacent thereto; that two of said slide members (17,22,31) present sliding surfaces (30) which are straight in their direction of motion; and that the means furthermore comprises control means (18,19,23,26,27, 32), with the aid of which by displacing on one hand one of the two slide members and the intermediate slide member (22) with reference to each other along the curved sliding surface (20) the angular position (a) of the member is controlled and on the other hand by displacing the intermediate slide member (22) and the second slide member with reference to each other along the straight sliding surface (30) rectilinearly the distance (H) of the member from the web is controlled independent of the control of angular position.
Claim 2
Dependent Claim 333 words
Means for controlling the position and location of a stationary member (12), used in a paper machine, acting on the web that is being manufactured and transversal with reference to the direction of travel of the web, by which means the distance (H) of said member (12) from the web and/or the position (a) of said member around its axis is controlled, and the body part of said member (12) being by mediation of this control means carried by both ends on the frame structures (41) of the paper machine, characterized in that the control means comprises on both ends of the frame of the stationary member (12) acting on the web a slide member structure comprising:- - a first slide member (17), on which the frame part (10) of said member (12) finds support; - a second slide member (31) supported by the frame part (41) of the paper machine; and - an intermediate slide member (22), connecting the first and second slide members (17,31); in that two of said slide members (17,22,31) present, acting against each other, sliding surfaces (20) shaped to represent part of a cylinder surface and their centre-of-curvature axis coinciding with the straight line defined by the tip edge (12') of said stationary member (12) or being immediately adjacent thereto; that two of said slide members (17,22,31) present sliding surfaces (30) which are straight in their direction of motion; and that the means furthermore comprises control means (18,19,23,26,27, 32), with the aid of which by displacing on one hand one of the two slide members and the intermediate slide member (22) with reference to each other along the curved sliding surface (20) the angular position (a) of the member is controlled and on the other hand by displacing the intermediate slide member (22) and the second slide member with reference to each other along the straight sliding surface (30) rectilinearly the distance (H) of the member from the web is controlled independent of the control of angular position.
Claim 3
Dependent Claim 38 words
Control means according to claim 1, characterized in that both the angular position (a) and the distance (H) from the web of the stationary member (12) has been arranged to be adjustable by the same control members (18,19,23,26,27,32).
Claim 4
Dependent Claim 74 words
Control means according to claim 2, characterized in that the control members by which either the angular position (a) or the distance (H) from the web of the stationary member is adjusted comprise a control screw (23) provided with a threaded part (32) disposed in conjunction with one of the two slide members (31), and which cooperates with a connecting piece (18,26) provided with corresponding threads and affixed to the first slide member (17).
Claim 5
Dependent Claim 26 words
Control means according to any one of claims 1-3, characterized in that the first slide member (17) has been provided with a curved sliding surface (20).
Claim 6
Dependent Claim 26 words
Control means according to any one of claims 1-3, characterized in that the second slide member (31) has been provided with a curved sliding surface (20).
Claim 7
Dependent Claim 27 words

Control means according to any one of claims 1-6, characterized in that when the intermediate slide member (22) is locked fast to the slide member (17) having a curved sliding surface (20), the adjustment of the height position (H) of the stationary member (12) is carried out by displacing with reference to each other the slide members (22,21) having straight sliding surfaces.
Claim 9
Dependent Claim 67 words
Control means according to any one of claims 1-7, characterized in that when the intermediate slide member (22) is locked fast to the slide member (31) having a straight sliding surface (20), the adjustment of the angular position (a) of the stationary member (12) is carried out by allowing the slide members (17,22) having curved opposed sliding surfaces (20) to be displaced with reference to each other.
