Patent number: 11673312Abstract: A system for advancement of a consumable in the form of a continuous sheet in a machine for manufacturing containers having a first pulling group of the sheet actuated by a first motor at the end of the manufacturing zone, a second pulling group of the sheet actuated by a second motor at the end of the manufacturing zone, a support and deviation element of the sheet after the second pulling group equipped with a load cell for estimating the tension, and a processor programmed to direct the individual actuation of the first and second motors, such that the pulling groups promote the advancement of longitudinal portions of sheet sufficiently different to correct deviations in the tension of the sheet with respect to a pre-established target tension. A method for intermittent advancement of the sheet having a correction phase of the tension wherein only the second motor is actuated.Type: GrantFiled: July 8, 2020Date of Patent: June 13, 2023Assignee: VOLPAK, S.A.U.Inventors: Silvio Quaglia, Carlos Yera Montoya

Patent number: 9950871Abstract: The present invention relates to a packaging method comprising the operation of transferring containers to an endless conveyor element moving forward continuously, conveying suspended containers and describing a closed trajectory imposed by a series of rotary diverting elements using to that end a container transferring device assembled on one of the diverting elements of the endless conveyor element, and rotating in a synchronized manner therewith. A device for putting the method into practice comprises a rotary body driving a plurality of clamps guided by mechanisms which can further slow down the displacement of the clamps without changing the rotating speed of the rotary body.Type: GrantFiled: October 18, 2013Date of Patent: April 24, 2018Assignee: VOLPAK, S.A.U.Inventors: Albert Prieto Male, Miguel Angel Leon Gonzalez

Patent number: 8790229Abstract: The invention relates to a method for continuously manufacturing containers made of a flexible material from a single continuous laminar band, or from several continuous laminar bands which will be longitudinally attached to form a single continuous laminar band, which will subsequently be transversely cut. In both cases, in a stage of the production phase a single laminar band, folded over itself along longitudinal fold lines, is obtained, the cross-section of which, open or closed according to the embodiment variant, forms a planar figure in which there is distinguished the upper base of the container, which in a variant of the method comprises a portion of band previously provided with holes and corresponding spouts, collapsed on one side, said single laminar band being susceptible of being driven by means of two drive rollers.Type: GrantFiled: July 1, 2010Date of Patent: July 29, 2014Assignee: Volpak, S.A.U.Inventor: Jordi Font Lletche

Patent number: 8672182Abstract: The invention relates to a discharge spout for flexible bags, of the type comprising a rigid plastic body forming a discharge passage and having a tube (3) intended to be inserted between two walls of a flexible bag and joined to such walls by means of sealing. The tube (3) has a smooth outer surface and two opposite flat flaps (4) extending externally in a mid-plane of said tube (3). The outer surface of the tube (3) forms, together with the surface (6) of the flat flaps (4), a sealing surface. The outer surface of the tube (3) has a middle area (5a), that is in the axial direction of the tube, in which the distance to the axis (7) of the tube is maximum, separating two side sections (5b, 5c) in which the distance to the axis (7) is decreasing toward the ends of the tube.Type: GrantFiled: July 6, 2009Date of Patent: March 18, 2014Assignee: Volpak, S.A.U.Inventor: Jaume Bonet Pedrol
