| 242418000 | Feeder associated with coil | 13 |
| 20090236461 | TENSION DEVICE AND HEAT EXCHANGE FIN MANUFACTURING MACHINE - The tension device comprises: a feeding unit for feeding a band-shaped metal plate to a press unit; and a holding unit for applying tension to the band-shaped metal plate. The feeding unit is constituted by a moving member and a feeding pin. The front end of the feeding pin has a slope face so as to engage with a collared through-hole of the band-shaped metal plate when the moving member moves in a feeding direction of the band-shaped metal plate and so as to disengage therefrom when the moving member stops and moves in the reverse direction. The holding unit has a holding member, which holds and applies prescribed tension to the band-shaped metal plate when the moving member stops and which releases the band-shaped metal plate when the moving member starts to move in the feeding direction. | 09-24-2009 |
| 20100025514 | METHOD AND APPARATUS FOR WINDING UP METAL STRIPS ONTO A WINDING MANDREL - The invention relates to a method and an apparatus for winding up metal strips ( | 02-04-2010 |
| 20100116923 | METHOD AND DEVICE FOR THE CONSTANT-TENSION FEED AND TAKE-UP OF A YARN FED TO A TEXTILE MACHINE - A device for controlling the feed of a yarn to a textile machine operating intermittently on the yarn, there being provided elements to sense the tension of the yarn and elements for measuring and modifying its feed speed, all connected to control and regulator elements for the tension and speed parameters, which continuously measure the values of both parameters during the feed of the yarn to the textile machine so as to act on a rotary member in order to modify the tension of the yarn when necessary. The rotary member is movable in a controlled manner in the two opposing directions of rotation to feed the yarn to the textile machine or to rewind it in order to prevent its accumulation in correspondence with the machine, the tension of the yarn fed or rewound being maintained at constant values. | 05-13-2010 |
| 20100193623 | ROLLING OF A STRIP IN A ROLLING TRAIN USING THE LAST STAND OF THE ROLLING TRAIN AS A TENSION REDUCER - A rolling train for rolling a strip has a number of rolling stands and a coiler. The rolling stands have work and backing rolls. Data of the strip are fed to a control device of the rolling train which determines individual pass reductions for the rolling stands based on the data. It controls the main rolling stands and the coiler such that the strip is rolled in the main rolling stands according to the individual pass reductions and then coiled up. It determines the individual pass reductions such that they are zero and controls the rolling stand arranged directly upstream of the coiler such that—with respect to this main rolling stand—the tension in the strip on the outlet side is less than on the inlet side, but the strip runs through this rolling stand without undergoing any forming, at least on one side. | 08-05-2010 |

| 20110272516 | MACHINE FOR UNROLLING AND LATERALLY ALIGNING RIBBONS - A machine for unrolling and aligning ribbons of fabrics, synthetic materials and the like, particularly for conveyor-belt cutting units and the like, comprising a supporting element that supports a roll of ribbon, a motorized device for unrolling the roll constituted by the ribbon, the machine further comprising a first assembly for reading the tension of the unrolled ribbon in order to adjust the motorized device so as to eliminate the tension of the unrolled ribbon, means for the lateral sliding of the unrolled ribbon, which is substantially free from tensions, for its alignment on a worktable, and a second assembly for reading the lateral deviation of the unrolled ribbon. | 11-10-2011 |
| 20120181367 | Accumulator with Tensioning Device - The present application provides a yarn accumulator for use with a yarn sausage in a heat setting line. The yarn applicator may include a sled in contact with the yarn sausage and a tensioning device in communication with the sled. The tensioning device applies a variable tension to the sled based upon the length of the yarn sausage. The tensioning device may include a sled pulley in communication with the sled, a ratioed pulley set in communication with the sled pulley, a counterweight pulley in communication with the ratioed pulley set, and a counterweight in communication with the counterweight pulley. | 07-19-2012 |
| 20120318905 | UNREELING ASSEMBLY, PARTICULARLY FOR LABELING DEVICES - An unreeling assembly, particularly for labeling devices, comprising a supporting frame for at least one reel of continuous film which is supported by a respective reel support, which can rotate about an unreeling axis of the reel, and a motorized traction drum, which is designed to unreel the continuous film from the reel of continuous film, between the reel of continuous film and the traction drum there being at least one tensioning element, which is movable, with respect to the supporting frame, along a respective movement path, elements being provided for estimating the radius of the reel of continuous film as a function of the data related to the angular velocity of the reel, to the speed of the film drawn by the traction drum and to the position of the tensioning element with respect to the supporting frame along the respective movement path. | 12-20-2012 |
| 20130240657 | APPARATUS TO DEPLOY AND EXPAND WEB MATERIAL - A dispenser to deploy and expand cut web material uniformly to form a three dimensional lattice. The unexpanded web material is substantially longer than it is wide. The web material is die cut and has essentially parallel longitudinal strands on opposite transverse sides. The dispenser tracks the threaded web material over three rollers, and uses an adjustable braking mechanism that creates diagonal web tension to pull the paper from the roll. After the web material is threaded through the mechanism, simply pulling the web material on the opposite side from the rollers deploys and expands it simultaneously. The unit can accommodate a plurality of rolls of web material mounted to deploy and expand either individually or simultaneously. The web material itself may have more than one layer. An exemplary embodiment of the dispenser is a motorized version, where a motorized guide wheel assembly pulls the web material, thereby eliminating the necessity of manual deployment. | 09-19-2013 |
| 20130270381 | METHOD FOR STORING AN ELEMENTARY SEMI-FINISHED ELEMENT IN A PLANT FOR PRODUCING TYRES AND DEVICE THEREFOR - A method and device for the storing of an elementary semifinished element in a plant for the differentiated production of tyres, wherein the elementary semifinished element is deposited, associated with a service film, on a collection support, into coils substantially disposed in side by side relationship forming adjacent layers deposited in opposite spiralling directions, at a predetermined winding angle, and wherein winding portions are present that are obtained by depositing the elementary semifinished element at a winding angle substantially equal to 0, for a circumferential angle less than 360°, in the transition between different spiraling directions. The winding angle is determined as a function of the dimensional parameters of the collection support and the elementary semifinished element. | 10-17-2013 |
| 20140306051 | YARN FEEDER OF STORAGE TYPE WITH MAGNETIC BRAKE - Yarn feeder including a body carrying a drum on which turns of yarn from a spool are wound; a tension sensor for measuring exiting yarn tension value, a braking member including a first permanent magnet and a fixed second magnet, regulator for varying action the second magnet exerts on the first permanent magnet, and a control unit to control the regulator. The first magnet is annular and movable parallel to the axis of the drum and along it between a first position where the first permanent magnet enables pressing the yarn against a counteracting element fixed to the drum and a second position where this effect does not occur. The control unit receives tension values measured by the tension sensor, comparing them with a predetermined value and intervening in real time on the regulator to adjust tension value to predetermined value when these two values do not coincide. | 10-16-2014 |
