20140123605 | WRAPPING METHOD - A method for wrapping a load with a film by a wrapping machine including an unwinding apparatus provided with a reel of the film includes moving the wrapping apparatus and the load in relation to one another and unwinding from the reel an established effective length of film per revolution of the wrapping apparatus or of the load. The established effective length of film is calculated with the formula: where: S | 05-08-2014 |
20140033657 | WRAPPING MACHINE AND METHOD - A machine for wrapping a load with a film made of synthetic plastics includes a first frame suitable for supporting second frame that rotatably supports around, and slidably parallel to, a wrapping axis at least one wrapping unit including a reel of the film and a roller assembly arranged for unwinding and prestretching the film. The second frame is slidably mounted on the first frame and is movable along an advancing direction that is transverse, and in particular orthogonal, to the wrapping axis. A conveyor is provided for moving the load along the advancing direction. The conveyor and the second frame are movable in a mutually coordinated manner to wrap the load with the film also while the load is moved along the advancing direction. | 02-06-2014 |
20120180433 | WRAPPING MACHINE AND WRAPPING METHODS - A wrapping machine for wrapping a product with a plastic film including a supporting frame with which a ring arrangement is associated that rotates around a wrapping axis of the film and around the product. The supporting frame further supports a carriage arranged for supporting a reel of the film and for supporting a first roller and a second roller for unwinding and stretching the film. A first motor and a second motor are mounted on the supporting frame and coupled, respectively, with the first roller and the second roller. | 07-19-2012 |
20120005985 | WRAPPING MACHINE AND WRAPPING METHODS - A wrapping machine for wrapping a product with a plastic film including a supporting frame with which a ring arrangement is associated that rotates around a wrapping axis of the film and around the product. The supporting frame further supports a carriage arranged for supporting a reel of the film and for supporting a first roller and a second roller for unwinding and stretching the film. A first motor and a second motor are mounted on the supporting frame and coupled, respectively, with the first roller and the second roller. | 01-12-2012 |
20100025517 | APPARATUS FOR CHANGING FILM REELS - An apparatus comprises a reel-holding unit for a wrapping machine for wrapping a product with a film unwound by a plurality of rollers from the reel and a reel-changing unit for replacing a finished reel with a new reel, the reel-holding unit and the reel-changing unit being mutually positionable in a reel-change configuration in such a manner that the new reel can be positioned instead of the finished reel, the reel-changing unit being provided with elements that define a curvilinear path for an initial portion of the film of the new reel, the elements being positionable in the reel-change configuration such that when a roller of the plurality of rollers is positioned at a curve, at least one of the elements is completely interposed between the film and the roller. | 02-04-2010 |
20090288372 | WRAPPING MACHINE AND WRAPPING METHODS - A wrapping machine for wrapping a product with a plastic film including a supporting frame with which a ring arrangement is associated that rotates around a wrapping axis of the film and around the product. The supporting frame further supports a carriage arranged for supporting a reel of the film and for supporting a first roller and a second roller for unwinding and stretching the film. A first motor and a second motor are mounted on the supporting frame and coupled, respectively, with the first roller and the second roller. | 11-26-2009 |
20090218193 | APPARATUS AND METHOD FOR ORIENTING ARTICLES - An apparatus comprises a moving arrangement for supporting and moving along an advance direction a plurality of articles; and orienting units movable along said advance direction and such as to contact and orient the articles by displacing angularly each article around an axis thereof so as to position the articles in respective output positions, the orienting units being such as to maintain the articles in contact with the moving arrangement, a detector being provided for each orienting unit for detecting an initial angular position of a respective article associated thereto and for promoting a desired angular displacement such that each article is brought in the output position. | 09-03-2009 |
20090062930 | System for Transmitting and Remotely Managing Data of a Machine - A system for transmitting and remotely managing data of a machine selected in a group comprising a packaging machine, a wrapping machine, a wood working machine tool, comprises a processing and exchanging data device communicating with a remote processing arrangement through a first communication network, wherein an intermediate processing device is interposed between said processing and exchanging data device and said remote processing arrangement so that transfer of said data between said processing and exchanging data device and said remote processing arrangement is achieved. | 03-05-2009 |
