One of the bearing blocks is supported on a final control element which is adjustable in the direction of motion of the belt. The control element is moved relative to a support frame with an adjusting device. This causes the angular orientation of the roller supported in the bearing block to vary relative to the longitudinal direction of the belt. The final control element is embodied as a car which is provided with wheels or the like and which can be moved about by the adjusting device relative to the support frame. ## Claims ### Claim 1 An apparatus for adjusting a bearing block of a rotating roller supporting a belt traveling in a given direction of motion, comprising: a final control element supporting a bearing block of a roller, the final control element being a carriage supported in a support frame and being movable relative to the support frame in the given direction of motion of the belt, for adjusting an angular orientation of the roller relative to the belt; an adjusting device for moving said carriage relative to the support frame; and a sliding carriage disposed in and being adjustable relative to the support frame in the direction of motion of the belt, and a second adjusting device for moving said sliding carriage, said carriage being adjustably supported in said sliding carriage in the given direction of motion of the belt. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein said carriage comprises wheels on which it is drivable. ### Claim 3 (depends on 1) The apparatus according to claim 1, which further comprises guide wheels attached to said carriage for defining a direction of motion thereof. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein said carriage has two face ends, and said adjusting device is disposed on one of said face ends. ### Claim 5 (depends on 1) The apparatus according to claim 1, wherein said second adjusting device is an adjusting spindle. ### Claim 6 (depends on 3) The apparatus according to claim 3, wherein said carriage is a plate having a top and an underside, the bearing block being secured on said top, and including guide wheels supported on and projecting from said underside of said plate. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein said carriage is a plate with end faces, and further comprising an adjusting cylinder disposed on said carriage, said adjusting cylinder having a piston and a piston rod releasably connecting said piston to one of the end faces of said plate. ### Claim 8 (depends on 7) The apparatus according to claim 7, wherein said adjusting cylinder is located laterally of said carriage. ### Claim 9 (depends on 7) The apparatus according to claim 7, wherein said adjusting cylinder is located laterally of said bearing block secured to said carriage. ### Claim 10 (depends on 1) The apparatus according to claim 1, wherein said sliding carriage is formed with two flanges, each having one groove formed therein for receiving and guiding support devices for said carriage, and said sliding carriage further having a groove formed therein for receiving and guiding guide wheels disposed underneath said carriage. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein said support devices are wheels laterally formed on said carriage and rolling in said grooves of said flanges. ### Claim 12 An apparatus for adjusting a bearing block of a rotating roller supporting a belt traveling in a given direction of motion, comprising: a final control element supporting a bearing block of a roller, the final control element being a carriage supported in a support frame and being movable relative to the support frame in the given direction of motion of the belt, for adjusting an angular orientation of the roller relative to the belt, wherein said carriage is a plate having a top and side faces, the bearing block being secured on said top, and including wheels supported on said side faces on which said carriage is drivable. ### Claim 13 An improved apparatus for adjusting a bearing block of a roller in a group of rollers supported in a support frame, wherein the rollers support a moving endless belt in a paper-production system, wherein the bearing block is supported on a final control element which is adjustable relative to the support frame in a longitudinal direction of motion of the belt by means of an adjusting device, and an adjustment of the final control element causes a defined variation of an angular orientation of the roller supported in the bearing block relative to the longitudinal direction of the belt, the improvement which comprises: the final control element being a carriage having wheels attached thereto, and including an adjusting device for moving said carriage relative to the support frame. ### Claim 14 (depends on 13) The apparatus according to claim 13, wherein the belt is a screen strip in a paper mill. ### Claim 15 (depends on 13) The apparatus according to claim 13, wherein the belt is a conveyor belt in a paper mill.
