  • Patent number: 6702277
    Abstract: The invention relates to a delivery device for the sections of a strip of film that are fed in a direction of conveyance, especially in a bead welding machine, comprising a rotor (40) that is driven and rotated around an axis (40) lying parallel thereto on the plane of conveyance with several contact areas that extend radially towards the axis of rotation (40) and which grasp successively fed strip sections in an operational mode, deflect said strip sections from the plane of conveyance and deliver them to a delivery station, whereby each respective contact area (10) of the rotor comprises suction areas (12) that can be subjected to an underpressure to hold said strip sections on the contact areas (10) when the contact areas (10) of the rotor move through the segment of a circle (14) between a first and a second position of rotation (16 or 18). In order to achieve trouble-free delivery of said strip sections, the angle of the circle segment (14) can be adjusted within limits.
