  • Rotary cutting and/or sealing mechanisms
    Patent number: 6805181
    Abstract: A rotary mechanism for cutting and/or sealing a web has a pair of counter-rotating rotors mounted on parallel axes and having radially projecting arms between which the web is momentarily gripped for cutting and/or sealing. Sealing is performed by heated pressure outer faces on the rotor arms. Cutting is performed by cutter and anvil bars on the opposed arms engaging the web. Bearer faces on the arms beyond the pressure faces set a gap between the pressure faces and a rectangular-section tongue and groove in mating contact faces one side of the pressure faces locate the pressure faces laterally. The cutting means are adjusted by a wedge bar bearing on the inner face of the cutter bar or anvil. The wedge bar is movable in the direction of rotation and has an outer face inclined in the same direction. Means accessible from the leading and/or trailing faces of the rotor arms are provided for adjusting the wedge bar and clamping the cutter and anvil bars.
