Patent number: 11081295Abstract: A winding apparatus is disclosed for winding material around a core of flat shape rotated around a rotation axis carried by a crank that is in turn carried by another crank, the three rotation axes of the core and of the two cranks being motorized independently by respective electric cams, with three distinct laws of motion programmed to cancel the variations in position and speed of the material entering the core. The winding apparatus is used for the production of electric energy storage devices.Type: GrantFiled: February 12, 2018Date of Patent: August 3, 2021Assignee: MANZ ITALY S.R.L.Inventor: Luca Zambonelli

Patent number: 10916794Abstract: A winding apparatus that produces electrical energy storage devices includes a rotatable winding core on which two electrode strips and two separator strips are wound, strip guides which guide the various strips along feeding paths, and at least one rotatable and/or slidable portion that supports at least one strip guide. The rotatable and/or slidable portion rotates and/or slides, respectively, to adjust the position of the respective strip according to an increase in the diameter of the wound product in order to have the desired insertion direction of the strip with respect to the peripheral surface of the product.Type: GrantFiled: April 18, 2017Date of Patent: February 9, 2021Assignee: Manz Italy S.r.l.Inventor: Massimiliano Sale

Patent number: 10020541Abstract: The invention relates to a method for forming a monocell or a bi-cell for a lithium-ion electric energy accumulating device, wherein it is provided to first laminate, in a first laminating unit, a first arrangement comprising a first electrode and two separating elements, so as to obtain a multilayered laminated element. In the first arrangement, the electrode is interposed between the two separating elements without yet being laminated to either of the two separating elements. The method then provides to form a second arrangement comprising the multilayered laminated element and a second electrode. The method finally provides to laminate the second arrangement in a second laminating unit, so as to obtain the cell.Type: GrantFiled: November 10, 2014Date of Patent: July 10, 2018Assignee: Manz Italy S.R.L.Inventors: Massimiliano Sale, Marco Vivarelli
