Santi Application (Patent) No. 200510084722.0 Date of Application 2005.07.12 Certification Date Auditing Announcement No. 1721276 Auditing Notice Day 2006.01.18 Manual CD-ROM D0603-1 Main Classification Number B65B7/20(2006.01) I Classification Number B65B7/20(2006.01)I Division Original Application No. 2004.7.12 EP 04425515.6 Abstract The invention describes a high-speed folding device (1) of a packaging machine for pourable foods. The device includes a conveying mechanism (21) for continuously conveying a sealed package bag with pourable food along a forming path (B) (3) And each package (3) has at least one folded portion (6, 7) to form a corresponding finished packaging container (2); the folding mechanism (70, 71.72) has at least one interacting surface (75, 76, 82) ), interacting with the packaging bag (3), performing at least one forming operation of the packaging bag; and an actuating mechanism (85) for bringing the interaction surfaces (75, 76, 82) in the same direction and with the packaging bag (3) The same movement speed movement so as to avoid any slippage when coming in contact with the packaging bag (3). Sovereignty item 1. A folding apparatus (1) for a packaging machine for pourable foods, comprising: a feeding mechanism (21) for continuously conveying a sealed package bag with pourable food along a forming path (B) (3) Each of the packaging bags (3) has at least one folded portion (6, 7) to form a relatively finished packaging container (2); and a folding mechanism (70, 71, 72) having at least one interacting surface (75, 76, 82) interacting with the packaging bag (3) to perform at least one forming operation of the packaging tape; characterized in that it further comprises an actuating mechanism (85) enabling the interaction surface (75, 76, 82) move in the same direction and at the same speed of movement as the packaging bag (3) so as to avoid any slippage when in contact with the packaging bag (3).
