Patent application numberDescriptionPublished
20080277820Moulds for Moulding Objects Made of Plastics and a Method for Producing a Mould Element - A mould comprises at least two die parts, each die part comprising a recess for forming a portion of an object and a conduit arrangement through which a cooling fluid can flow, the conduit arrangement comprising a curved conduit which surrounds the recess, an inlet conduit having a supply portion which leads into the curved conduit and an outlet conduit having a discharge portion which leaves the curved conduit so as to define a path for the cooling fluid, the curved conduit, the supply portion and the discharge portion being arranged so as to be interceptable by a common plane that contains the path.11-13-2008
20090140462Apparatuses for Forming Objects With Undercut Portions - An apparatus for forming an object from a dose of plastics comprises a die arrangement provided with a cavity for receiving said dose and with at least two parts that are reciprocally movable for shaping an undercut portion of said object, at least one fluid for applying a clamping force so as to keep said at least two parts in contact; said at least one fluid is such as to increase discontinuously said clamping force from an initial force that is applicable when said dose is substantially contained in said cavity to a final force applicable when said at least two parts shape said undercut portion.06-04-2009
20100028479APPARATUSES AND METHOD - An apparatus comprises a conveying device provided with seat elements arranged for receiving objects, the seat elements being movable along a curved path, and a further conveying device provided with a transferring arrangement arranged for delivering the objects to, and/or removing the objects from, the conveying device, wherein the transferring arrangement comprises coupling elements arranged for engaging the seat elements in such a way that the seat elements and the transferring arrangement are maintained mutually coupled along a portion of the curved path.02-04-2010
20100112110APPARATUS FOR TRANSFERRING DOSES - An apparatus for transferring doses includes a forming arrangement for forming an object from a dose of flowable material and a transferring arrangement for transferring the dose to the forming arrangement. The transferring arrangement has a recess for receiving the dose. The recess is provided with a rolling arrangement for guiding the dose inside the transferring arrangement.05-06-2010
20110020482APPARATUS FOR TRANSFERRING DOSES OF PLASTIC MATERIAL - An apparatus includes a transferring arrangement arranged for delivering doses of plastic material to a compression-molding device. The transferring arrangement includes a containing arrangement arranged for receiving the doses and a movement-promoting arrangement received in the containing arrangement and movable with respect to the containing arrangement for delivering the doses to the compression-molding device. The movement-promoting arrangement is made at least partially of a porous material.01-27-2011
20110045115APPARATUS FOR TRANSFERRING OBJECTS - An apparatus for transferring objects includes a receiving arrangement, a transferring arrangement for transferring an object towards the receiving arrangement, the transferring arrangement having a recess for receiving the object, the recess being defined by a wall arrangement, and a driving arrangement arranged for moving at least part of the wall arrangement so as to change a passage section of the object through the recess.02-24-2011
20110109018METHOD AND APPARATUSES - An apparatus includes a first operating machine arranged for processing objects, a second operating machine positioned downstream of the first operating machine and arranged for further processing the objects, an accumulating arrangement interposed between the first operating machine and the second operating machine and arranged for receiving the objects, and a command and control arrangement arranged for detecting a parameter indicating the quantity of the objects contained in the accumulating arrangement and regulating the operation of the second operating machine on the basis of the parameter.05-12-2011
