Title: Improvements in a roll for centering and aligning strip
IPC: B21C47/34
Filed: 1956-09-14
Abstract: 843,939. Rollers. UNITED STATES STEEL CORPORATION. Sept. 14, 1956 [Oct. 18, 1955], No. 28221/56. Class 42 (2). [Also in Group XVI] A roller for centring a moving strip with respect to a predetermined lateral path, comprises a pair of spaced-apart end sections mounted on a shaft on either side of an intermediate rim section, each of the end sections being deflected under load to rotate about an axis inclined with respect to the axis of the other end-section. As shown, a shaft 2, Fig. 1, is rotatably mounted in spaced-apart bearings 4. The shaft 2 may be driven through an extension 6. Roller sections, keyed or otherwise secured to each end of the shaft 2, comprise a hub 10, web 12 and a rim 14. The rim may be cylindrical, frusto-conical or may have a slightly concave exterior. An intermediate roller-section 16 comprising a strip-supporting surface 18 may be cylindrical or slightly concave and is supported at its outer ends by stepped portions 20 on the end-sections 8 so as to rotate in unison therewith. Engagement of a strip with the endsections causes deflection of these sections, such that when the angle of wrap is 180 degrees their axes of rotation are inclined to the transverse centre line of the roller away from the direction of approach of the strip. Should the strip deviate to the left as seen in Fig. 1, the left-hand section tilts and thus exerts a force tending to restore the strip towards the right. In a modification (Fig. 5, not shown), the roller-sections are supported by roller-bearings on a shaft bent away from the direction strip approach when the wrap-round is 180 degrees. In a further modification (Fig. 6, not shown), each rollersection is supported by a pair of roller-bearings on a shaft having a centre portion which is in a plane normal to the desired path of travel of the strip passing therearound. In a further modification, a straight shaft 80, Fig. 7, is supported in bearings 82 and has an intermediate rollersection 84 supported between end-sections 86. The outer ends of the sections 86 are supported on the outer races 92 of ball-bearings 94. Inner races 96 are secured against outward axial movement by collars 98. After passage around the centring roller the strip B passes around a roller 106 having a strip-supporting surface 108 of less width than the strip. If desired, the strip may also pass around a roller 106 in advance of the centring roller. When it is desired to guide strips narrower than the intermediate section this section, which may be formed of two parts, is split. Specifications 709,908 and 717,671 are referred to. Reference has been directed by the Comptroller to Specification 735,561.
