| Number | Title | Issue Date |
| 7251978 | Roll stand for producing plane roll strips having a desired strip profile superelevation The aim of the invention is to improve known roll stands (10) which are characterized by working rolls (1,2) of various diameters, in such a way that a strip is obtained which is largely free of tensions and undulations, has a desired strip profile sup... | 08/07/2007 |
| 7185522 | Side supported 6-high rolling mill A 6-high rolling mill has work rolls which have offsets, relative to the intermediate rolls, such that during operation there is a net horizontal force acting to urge the work rolls into engagement with the support rolls whereby substantially all horizontal support ... | 03/06/2007 |
| 6151943 | Rolling machine and rolling method There are provided a rolling machine and a rolling method in which the strip crown and shape control capability for a narrow-width strip is improved, so that the adequate strip crown and shape control capability for strips of various widths from a narrow ... | 11/28/2000 |
| 5560237 | Rolling mill and method To eliminate a vertically asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of upper and lower work rolls 2, 3 during rolling, a device for comparing values measured on the upper and lower sides and calculatin... | 10/01/1996 |
| 5165266 | Chockless roll support system A chockless work roll support and positioning apparatus and method comprises a pair of brackets for each end of each work roll and having a pair of work roll support rollers rotatably mounted on each bracket. Each bracket is connected to at least one actu... | 11/24/1992 |
| 5007273 | Four-high roll or six-high roll stand having laterally supported working rolls In a multi-roll stand having laterally supported working rolls 4, each working roll 4 is supported at at least one side against a radially unmounted lateral intermediate roll 5, which, for its part, is supported against a first, radially mounted supportin... | 04/16/1991 |
| 4918965 | Multihigh rolling mill A multi-high rolling mill has upper and lower work rolls, upper and lower backup rolls, and an intermediate roll disposed therebetween. All of the work rolls, backup rolls and intermediate roll are arranged in a perpendicular direction. The intermediate r... | 04/24/1990 |
| 4800742 | Rolling mill for making a rolled product, especially rolled strip During operation of a rolling mill the roll gap and roll shape change, because of the influence of heat, bending of the working rolls or the roll mounting, wear and the like, and must be compensated and/or balanced to make a planar product, particularly a... | 01/31/1989 |
| 4781050 | Process and apparatus for producing high reduction in soft metal materials A process and apparatus for producing increased reductions in strip material, particularly soft metal strip materials, are disclosed. The process and apparatus utilize a rolling mill having at least two offset work rolls driven at a peripheral speed ratio... | 11/01/1988 |
| 4736678 | Apparatus for selectively positioning rolls in a calender roll stack A hydraulic adjustment motor containing a piston-and-cylinder unit is provided at the roll surface of a roll to be moved to position the roll surface relative to another roll surface of a further roll. Each adjustment motor is arranged between the related... | 04/12/1988 |
| 4719784 | Roll bending apparatus for rolling mill A roll bending apparatus for use in a multi-stage rolling mill adapted for rolling a hard material or a thin sheet material with a high uniformity of thickness along the breadth, with a high degree of accuracy and low energy. The rolling mill has work rol... | 01/19/1988 |
| 4614103 | Rolling mill Horizontal supporting rolls disposed at a lateral side of the work rolls support the work rolls in the direction of travel of the rolled material, and horizontal back-up rolls disposed at a lateral side of the horizontal supporting rolls back-up the horiz... | 09/30/1986 |
| 4598566 | Four-high roll stand with offset working rolls A roll stand has a frame and a pair of small-diameter and substantially parallel working rolls defining a workpiece nip. Thus a strip to be rolled passes in a horizontal upstream-to-downstream direction through the nip. Respective pairs of upper and lower... | 07/08/1986 |
| 4563888 | Six-high roll stand with braced and removable working rolls A roll stand has a frame having two sides spaced apart transversely of a workpiece travel direction and formed with throughgoing windows and a pair of vertically spaced traverses extending between the frame sides. Two outer backup rolls centered on parall... | 01/14/1986 |
| 4552008 | Rolling mill for sheet material A rolling mill for the treatment of sheet material comprises two work rolls (1, 2) which define a nip between which a web of material (3) is passed for rolling. The work rolls (1,2) are offset in a horizontal direction relatively to back-up rolls (4,5), s... | 11/12/1985 |
| 4539834 | Rolling mill A rolling mill is disclosed in which, in order to improve the quality of rolled products, a work roll with a small diameter is used and is offset by a predetermined distance from the reduction line and the horizontal bending force is exerted to the small-... | 09/10/1985 |
| 4494396 | Multistage rolling mill with flatness control function The present invention considerably improves the rolling mill in the flatness control function, by arranging either of a pair of upper and lower work rolls as a small-diameter roll, offsetting the small-diameter work roll by a required distance in the roll... | 01/22/1985 |
| 4059976 | Rolling mill A rolling mill has a pair of working rolls each provided with one or more sag-compensating back-up rolls on the respective side of the rolling plane having a fixed support beam with a roll shell rotatable about the beam and hydrostatic support means mount... | 11/29/1977 |
