Apparatus for controlling the position and location of a stationary device of a paper machine which acts on a paper web being manufactured therein

Claim 1

Apparatus for controlling the position and location of a stationary device which constitutes a component of a paper machine and which acts on a paper web being manufactured therein over a transverse dimension thereof relative to the direction of travel of the web, said control apparatus being operative to control one or both of the distance of the device from the web and the angular orientation of the device, the device including a frame portion which is carried at each respective transverse end thereof by frame structure of the paper machine through a respective control apparatus, said control apparatus comprising: a slide assembly including, a first slide member supporting a respective end of the frame portion of the stationary device and having a sliding surface; a second slide member supported by the paper machine frame structure and having a sliding surface; and an intermediate slide member having two sliding surfaces, said intermediate slide member being situated between said first and second slide members and forming a first pair of sliding surfaces with the first slide member and a second pair of sliding surfaces with the second slide member; wherein one pair of sliding surfaces presented by said intermediate slide member and one of said first and second slide members have a curved segment configuration having a center of curvature which is substantially coincident with or immediately adjacent to a straight edge defining a tip of the stationary device; wherein the other pair of sliding surfaces presented by said intermediate slide member and the other of said first and second slide members have a linear configuration extending in the direction of movement thereof; and wherein said control apparatus further includes adjusting means for moving said one of said first and second slide members and intermediate slide member with respect to each other on said curved sliding surfaces to control the angular orientation of the stationary device and for moving said other of said first and second slide members and intermediate slide member with respect to each other on said linear sliding surfaces to control the distance of the stationary device from the web independently of the angular orientation of the stationary device.
