20090159631 | TENSION CONTROL FOR A SHEET MATERIAL FEEDER - A sheet material feeder includes a sheet material web, a vacuum box applying a tension force to a portion of the sheet material web extending into the vacuum box by applying a first vacuum force on the sheet material web, a first drive feeding the sheet material web into the vacuum box, a second drive pulling the sheet material web out of the vacuum box, and a system for applying a braking force to the sheet material web proximate to the vacuum box only during a decelerating movement of the sheet material web at the second drive. | 06-25-2009 |
20110006096 | DEVICE AND METHOD FOR THE CONSTANT TENSION FEEDING OF THREADS OR YARNS FED IN A DISCONTINUOUS WAY - Device and method for constant tension feeding, threads or yarns fed to textile or winding machine or metallic wire to similar machine, in discontinuously with phase sequences. The thread motion has at least first and second feeding or absorption states following each other in time. A controller, connected to a tension detector and thread accumulator, intervenes on the accumulator based upon tension value from the detector. A compensator, between the accumulator and tension detector, cooperates with thread to compensate variation of feeding or absorption state of the thread upon passage between each first and second feeding or absorption state. The controller intervenes to modify the accumulator's action on thread and maintain tension value detected by the detector at set value. Interaction between thread and compensator keeping constant tension value during the changing phase of the feeding state. The compensator freely moveable under action of thread relative to a resting position. | 01-13-2011 |
20110057013 | PAPER DISCHARGE DEVICE AND IMAGE FORMING APPARATUS HAVING THE SAME - A paper discharge device and an image forming apparatus include a holding unit | 03-10-2011 |
20120012634 | PRINTING DEVICE AND ROLL DIAMETER CALCULATING METHOD AND PROGRAM - A printing device includes a first roller for rotatably retaining a roll body where a medium is rolled, a first motor for rotating the first roller, a second roller installed further to the downstream side of the roll body in the feeding direction of the medium to feed the medium in the feeding direction or in a reverse feeding direction which is opposite to the feeding direction corresponding to the rotating direction, a second motor for rotating the second roller, and a controller which causes the medium to become slack the first roller and the second roller by feeding the medium by a predetermined feeding amount in the reverse feeding direction by the second motor, and then rotates the roll body in a winding-up direction by the first motor so that the slackness decreases to calculate the diameter of the roll body based on the rotation amount of the first roller at that time and the predetermined feeding amount. | 01-19-2012 |
20150069107 | Method For Controlling Feeding Length Of Wire And Displacement Sensing System For The Same - A method for controlling a feeding length of a wire is provided. The wire is frictionally engaged with and fed by a driving wheel mounted on a driver. The method comprises steps of: providing a displacement sensing device comprising a driven wheel and a sensor for sensing the number of revolutions of the driven wheel, the driven wheel being frictionally engaged with the wire and configured to be rotated under a frictional engaging force therebetween as the wire is fed; starting the driver to rotate the driving wheel, so that the wire is fed forward and the driven wheel is rotated as the wire is fed; calculating an actual feeding length of the wire based on the product of the number of revolutions of the driven wheel sensed by the sensor and the perimeter of the driven wheel; and controlling the feeding length of the wire based on an error between a predetermined feeding length of the wire and the calculated actual feeding length of the wire with closed loop feedback control until the error becomes zero or within an allowable range. | 03-12-2015 |
