| 20110219835 | ROLLER DEVICE WITH ADJUSTER DEVICE - The invention relates to a roller device ( | 09-15-2011 |
| 20140260474 | MEASURING THERMAL EXPANSION AND THE THERMAL CROWN OF ROLLS - Systems and methods for measuring the thermal crown of rolls in-situ (e.g., at high temperature) either inside or outside the rolling mill can include sensors that measure propagation times of mechanical waves through the rolls. In some embodiments, one or more sensors are used to measure the propagation times of ultrasonic waves traveling inside the roll and normal to the roll's axis. These measurements can be taken when the roll is still hot and can be used to determine in real-time the thermal expansion at various points along the roll. | 09-18-2014 |
| 20140305176 | UNIVERSAL ROLLER SWAGING MACHINE WITH TOOL WEAR MONITOR - A roller swaging machine is provided for swaging first and second work pieces together. The roller swaging machine may include a base, a work piece support assembly, a tool carriage assembly, a spline feed assembly, and a linear sensor. In an embodiment, a tool carriage assembly may be configured to support an expander tool having a tapered mandrel, the spline feed assembly may be configured to be coupled to the tapered mandrel of the expander tool, and the linear sensor may be configured to measure axial movement of the tapered mandrel. | 10-16-2014 |
| 072130500 | To control predetermined sequence of operating movements (e.g., of one tool operating on work) | 2 |
| 20100294009 | CONVEYING DEVICE, HOT ROLLING APPARATUS, CONVEYING METHOD, AND HOT ROLLING METHOD - A conveying device includes a plurality of conveying rollers supported in parallel at predetermined intervals, and conveys a workpiece to a heat-retaining/heating furnace from a rolling mill by the conveying rollers. The conveying device includes an impact prediction data collecting unit and a control unit. The impact prediction data collecting unit acquires data on the upstream of the heat-retaining/heating furnace. The data is used to predict the magnitude of an impact applied to rollers in the furnace, which are positioned in the heat-retaining/heating furnace, of the conveying rollers by the workpiece. The control unit predicts the magnitude of an impact from the data, which is acquired by the impact prediction data collecting unit, and adjusts the conveying speed of the workpiece in the heat-retaining/heating furnace according to the magnitude of the impact. | 11-25-2010 |
| 20160045948 | METHOD OF MANUFACTURING CVT BELT - In order to restrain the length of an endless metal ring from dispersing, a method of manufacturing a CVT belt has a first-stage stretching step of extending a circumferential length of an endless metal belt by widening distances among rollers. The method includes a measuring step of measuring a spring-back amount of the endless metal belt in the first-stage stretching step. The method includes a calculating step of calculating a predicted spring-back amount that is predicted from the measured spring-back amount. The method also includes a second-stage stretching step of stretching the endless metal belt to process the endless metal belt into a predetermined circumferential length by further widening the distances among the rollers based on the predicted spring-back amount. | 02-18-2016 |
| 072140100 | Including plural sensors or sensor responsive to plural conditions | 2 |
| 20090113968 | Method for Detecting Strip Edges - A method of detecting strip edges in a cold rolling mill and/or strip-forming installation in which the strip edges ( | 05-07-2009 |
| 20140318202 | STRAIGHTENING DEVICE WITH HYPERBOLIC ROLLS FOR METAL PRODUCTS AND CORRESPONDING METHOD - Straightening device for long or rod-shaped metal products, comprising an upper roll unit and a lower roll unit, wherein the upper roll unit is mobile and can be positioned vertically at least in the step where a passage gap of said products is set to a desired value, wherein a hydraulic safety/control device is associated with the lower roll unit and comprises a single-effect hydraulic actuator of the selectively yielding type when an overload condition higher than a predetermined value is detected on said lower roll unit. | 10-30-2014 |
| 072140200 | To control operation of interlock | 1 |
| 20090025443 | RADIAL ROLLER HEAD - Radial roller head with rollers distributively arranged in a holder under the same angular separations and in axial separations around a roller axis, the roller surfaces of which have an increasing progression in a spiral manner around the circumference in the counter clockwise direction. A gear wheel drive couples the rollers together. A locking device automatically locks into place after each full roller rotation and is released before each roller procedure via a moveable locking element. A drive device turns the rollers after release of the locking device up to the contact of the roller surfaces with a tool, in order to then be further turned through friction therewith. An electromagnet connected with the locking element, is arranged in the radial roller head with an electrical energy source and a switch connecting the energy source with the electromagnets when the switch is actuated via the work piece or another actuating device. | 01-29-2009 |

| 20120279267 | METHOD FOR CONTROLLING LATERAL GUIDING DEVICES FOR A METAL STRIP - The invention relates to a method for controlling a lateral guiding device for a metal strip ( | 11-08-2012 |
| 20220134400 | PRESS ROLL APPARATUS AND METHOD FOR CONTROLLING PRESS ROLL APPARATUS - A first exemplary aspect is a press roll apparatus including: a first roll and a second roll configured to hold a workpiece therebetween to press the workpiece; a mobile unit configured to move the second roll; a detection unit configured to be able to detect a load that acts between the first and the second rolls; and a control unit configured to control the mobile unit. The control unit moves the second roll in a direction in which the second roll approaches the first roll in a state in which the workpiece is not held between the first and the second rolls, and sets a position of the second roll where the load detected by the detection unit has become equal to or greater than a predetermined value as an origin position. | 05-05-2022 |
