  • Patent number: 6186436
    Abstract: A method and apparatus for winding film includes haul-in rolls, a spindle, an airhorn, a kick-roll, and a belt or ropes to convey the film. A source of air creates an air curtain downstream of the spindle. The air curtain directs the leading edge of the film into the airhorn and over the spindle. A film guide located upstream of the airhorn guides a leading edge of the film back into its own nip. An air guide located between the film guide and the conveyor leading to the spindle prevents air from going back upstream of the airhorn. The guides are comprised of a non-stick material. Holes near the edge of guide allow air to exit the air horn, without perturbing the film where it tucks into its own nip. A static pinner may pin the leading edge of the film to the spindle. The spindle may have a winding surface tapered by less 0.03 inches per foot. The spindle has an air inlet, and outlet holes. The inlet area is greater than the hole area, by up to a 7:1 ratio.
