Abstract: A controlled deflection roll has a roll shell which is hydrostatically radially supported by internally disposed hydrostatic shoes. In order to axially position the roll shell, a mechanical locating link is provided which is disposed externally of the roll shell. The link is coupled at one end to an element attached to the roll shell, and is coupled at an opposite end to a fixed support, such as a floor stand. The end of the roll at which the locating link is disposed is thus axially fixed, while the opposite end of the roll remains free to float. The locating link can be connected to an oscillator to oscillate the roll shell axially during operation so as to distribute any non-uniformities in the roll shell and thus to mitigate their effect on the sheet.

Abstract: A heatable roller which can be heated from inside the roller body by a heating device. Provided radially outside the heating device are axially parallel bore holes uniformly distributed over the periphery of the roller body which are connected at the ends by annular chambers. The bore holes and the annular chambers form a closed system which is partially filled with water. This system operates to make the temperature uniform via condensation heating in the event of local temperature reduction.

Abstract: Ducts are formed from rigid or semi-rigid insulation boards by forming a plurality of longitudinally extending, spaced apart, parallel kerfs in a first major surface of each of the insulation boards which is adapted to be the interior surface of the duct. When the insulation board is formed into a duct of the preselected dimensions, the shoulders of the kerfs adjoining the interior surface of the duct abut and, preferably, the insulation material in the shoulders of the kerfs is compressed. The flexibility of the insulation boards, in the direction of the widths of the insulation boards, is controlled by increasing the depths and/or the widths of the kerfs and/or decreasing the spacing between the kerfs to make the insulation board more flexible and by decreasing the depths and/or the widths of the kerfs and/or increasing the spacing between the kerfs to make the insulation board less flexible.

Abstract: A roll having bending control has a rotating hollow roll and a non-rotatable crossbeam penetrating the hollow roll lengthwise. Arranged on the crossbeam in an axially parallel row, closely following one another, are supporting elements which can be actuated independently of one another by fluid pressurized medium. Supply lines are attached via angle units to a bar-type carrier which is fastened to the crossbeam by means of screws that can be manipulated from the outside. The screws have longitudinal bore holes through which the respective supply line is directly connected to the respective supporting element.

Abstract: A roller with controllable sag is provided with a revolving hollow roller and a non-rotating crosshead that crosses the hollow roller along its length and on which the hollow roller is supported by a series of supporting elements that are actuated by a pressure medium. Separate supply lines (13) lead to the supporting element and open out into a collection head (40) at the end (10') of the crosshead, to which the outer connection lines (53) are connected. The connection head (40) comprises a double-disc rotary slide valve (50) by which the lines (13, 53) can be interrupted and which in the closed state can be separated at a separation surface (47). The individual discs (51, 52) of the double disc rotary slide valve (50) keep both the supply lines (13) and connection lines (53) closed, thus facilitating replacement of the roller as and when required.

Abstract: A wheel bearing spindle is produced by an improved method which provides adequate structural clearance from the sharp edge of a wheel drum hub, while actually improving the effective yield strength of the spindle. The spindle is produced from a near net shape steel forging which has a cylindrical spindle and flat wheel flange radiating therefrom. The circular hub of a brake drum fits radially closely over the pilot, and abuts with the wheel flange. Therefore, the juncture of the pilot and flange needs to be relieved or cut away somehow, both radially and axially, in order to assure non interference with the circular edge of the hub, which could prevent the rest of the hub from intimately abutting the surface of the wheel flange. The radial component of the clearance is provided by conventionally machining a channel radially into the pilot. This can be done, since it does not weaken the flange.

Abstract: A tool for extracting bearings from a long shaft as well as method of doing same is disclosed. This method and tool begins with connecting a split sleeve about a stuck bearing. This sleeve is then placed in a case. One or more extension are then added, thus allowing the puller to reach bearings on long shafts. When a sufficient number of extensions are added, a cap having an extraction bolt, which engages the end of the bearing shaft inside of the puller is attached. The extraction bolt is then rotated in a clockwise manner which forces the puller, and the engaged bearing, in an outward manner from the bearing shaft. When the extraction bolt is rotated to the extent of its working range by being turned all the way in, the puller is disengaged from the bearing and an extension section is then removed. This allows the extraction bolt to be rotated in a counter clockwise manner to a point were it regains its full working range.
