| 20110094278 | METHOD TO CHECK AND CONTROL A ROLLER BENDING MACHINE FOR CONTINUOUSLY BENDING AN ELONGATED WORKPIECE AT VARIABLE CURVATURE RADII, AND MACHINE SO CONTROLLED - A method to check and control a roller bending machine for continuously bending an elongated workpiece at variable curvature radii in a bending machine using a series of rollers for bending, comprises the steps of measuring the distance of the elongated work piece in a point that is situated downstream the series of rollers for bending in successive instants, calculating a curvature radius of each bend section of the elongated workpiece, comparing the calculated curvature radius with the desired curvature radius and determining a difference between them, calculating the change of position to which an upstream roller has to be subjected in order to annul such a difference and operating the upstream roller on the base of the calculated change of position. A machine embodying the method is also described. | 04-28-2011 |
| 20110042877 | VISE PROVIDED WITH A MOVABLE JAW DEVICE HAVING SEPARATED APPROACHING AND CLAMPING STEPS IN A PIPE BENDING MACHINE DIE - A vise provided with a movable jaw device having separated approaching and clamping steps in a bending machine die, the vise ( | 02-24-2011 |
| 20110032542 | METHOD OF MEASURING A LENGTH OF SECTIONS OF EXTRADOS OR INTRADOS CURVES OF AN ELONGATED WORKPIECE, AND RELEVANT LENGTH MEASURING INSTRUMENT - A method of measuring a length of sections of extrados or intrados curves of an elongated workpiece travelling in a bending machine along a forwarding direction, the elongated workpiece having cross-sections each of which is separated by a neutral axis in both an extended portion and a compressed portion when the elongated workpiece is subjected to bending, and at least a neutral cross-section, i.e. not subjected to bending, neutral cross-section beyond which the bending of the elongated workpiece begins along the forwarding direction thereof, provides a measuring instrument positioned so that it engages either an extrados or an intrados point of the elongated workpiece near the neutral cross-section, but displaced therefrom in the forwarding direction of the elongated workpiece. Further, a measuring instrument on a bending machine that embodies the method is described. | 02-10-2011 |
| 20100281937 | MACHINE FOR CONTINUOUSLY BENDING AN ELONGATED WORKPIECE AT PREDETERMINED RADII - A machine for continuously bending an elongated workpiece at predetermined radii, machine that uses a series of driving rollers ( | 11-11-2010 |
| 20100206036 | PIPE BENDING MACHINE WITH BENDING MANDREL HAVING A LOAD BEARING STRUCTURE WHICH IS PARTICULARLY RESISTANT TO WORKING STRESSES - A pipe bending machine with bending mandrel having a load bearing structure which is particularly resistant to working stresses, comprises an extractor ( | 08-19-2010 |
| 20100101299 | PIPE BENDING MACHINE HAVING AN IMPROVED MOVEMENT TRANSMISSION TO A BENDING DIE - A pipe bending machine having an improved movement transmission to a bending die comprises a body ( | 04-29-2010 |
