摘要： 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. The spindle surface may have a non-stick surface, or have a liquid lubricant applied thereto. A yoke may be used to remove rolls, and the yoke contacts the spindle in substantially 360 degrees, or a push-off palm may be used to remove the roll and contacts the spindle in two places.

摘要翻译： 用于卷绕薄膜的方法和装置包括输送辊，主轴，气喇叭，踢脚辊以及用于输送胶片的皮带或绳索。 空气源在主轴下游形成气帘。 气帘将胶片的前缘引导到喇叭和主轴上。 位于气喇叭上游的胶片导片将胶片的前缘引导回自己的胶带。 位于胶片导向器和通向主轴的输送机之间的空气引导件防止空气回到气喇叭的上游。 导轨由不粘材料组成。 导轨边缘附近的孔允许空气离开空气喇叭，而不会影响胶片卷入其自身压区。 静态夹子可将胶片的前缘固定到主轴上。 主轴可以具有逐渐减小0.03英寸/英尺的卷绕表面。 主轴具有进气口和出口孔。 入口面积大于孔面积，比例高达7：1。 主轴表面可以具有不粘表面，或者具有向其施加的液体润滑剂。 磁轭可以用于去除辊子，并且磁轭以大致360度的方式接触主轴，或者可以使用推动式手掌来移除辊子并在两个位置接触主轴。
