Abstract:
A device for releasing and removing flexible synthetic material elements from a molding surface, comprising a molding surface on which the elements are arranged, a unit for gripping the elements that can be actuated from a lower position, in which it is in contact with the element, to an upper position, the grip unit comprising a tubular body that has a vertical axis and, in a downward region, an edge for compressing, in the lower position, the peripheral region of the element onto the molding surface, forming thereat a region that forms a seal with the surface, the molding surface being provided with a blower for conveying a stream of air under the element in order to release it from the molding surface.
Abstract:
An assembly for the compression molding of articles made of plastic material, composed of a main male plug and a complementary male plug which comprise a stem, actuated by an actuation element with a spindle guided in a tubular tang provided with a molding head cooperating with the main male plug; a first spring, arranged on the spindle acting between a collar of the spindle and the tubular tang; a second spring, arranged on the spindle acting on the collar or on the end of the tang that lies opposite the molding head, to determine an inactive molding step of the complementary male plug, a compression step, and a reduced compression step.
Abstract:
An apparatus for compression molding plastic articles, comprising at least one molding unit composed of an upper punch and a lower mold provided with a cavity for molding the articles, the punch and mold being aligned with each other and movable between a spaced position and a closer positions, feeders for feeding doses of plastic material to be molded, comprising at least one removal element for removing, in succession, individual doses from an extruder and depositing a removed dose in the molding cavity of the mold when it is spaced from the respective punch, supporting elements for temporarily supporting said dose above the molding cavity, associated with the mold, and actuators for actuating the supporting elements so as to release a dose into the cavity before compression start.
Abstract:
An apparatus for compression molding of articles made of plastics, comprising: molding means; feeding means for feeding doses of plastic material, which are provided with removal elements for removing in succession said doses from an extruder and transferring the doses onto said molding means; and conditioning means for conditioning temperature of said doses during transfer thereof from said extruder to said molding means.
Abstract:
An apparatus for molding and inserting in caps liners made of plastic material dispensed by an extruder, comprising: a dosage carousel; a molding carousel; an insertion carousel; a cap feeder for feeding said insertion carousel with caps, the carousels being rotatable about vertical axes and provided with seats for supporting multiple shuttles that are angularly equidistant concentrically to the rotation axes of the respective carousels, the dosage carousel having assemblies for taking in succession doses of plastic material from the extruder and depositing them onto the shuttles, the molding carousel having assemblies for molding in succession liners on the shuttles and the insertion carousel having assemblies for removing in succession the liners from the shuttles and inserting them in respective caps fed by the feeder; and a first, second and third star, for shuttle transferring at the respective carousels.
Abstract:
An apparatus for transferring fruit products from a feeder conveyor to a receiving conveyor that is perpendicular thereto, the apparatus comprising a transfer device which comprises a supporting beam for a plurality of grip elements suitable to grip at least one row of equidistant products, means for moving the beam between a picking position, in which the elements grip at least one row of products at the output of the feeder conveyor, and a release position, in which the grip elements are aligned with the receiving conveyor, the beam, in the alignment position, being actuated with a motion that is equal to, and in step with, the receiving conveyor in order to allow to deposit onto the receiving conveyor, with zero relative speed, the row of picked products.
