    • A take-off apparatus for plastic blown sheet that is collapsed has a deflecting roller rotatably mounted for transporting the blown sheet and an air turning bar for receiving the blown sheet from the deflecting bar along a transport plane defined therebetween. The blown sheet passes around a peripheral portion of the air turning bar thereby defining a support arc region of the at least one air turning bar about which the blown sheet is supported. The air turning bar has air outlet openings disposed in the support arc region through which compressed air is ejected to support the blown sheet. The air turning bar has an arc-shaped axis defining a plane of curvature which is oriented such that the peripheral portion presents a concave surface in which the air outlet openings are disposed and which opposes the blown sheet.
    • 用于挤压的塑料吹塑薄片的取出装置具有可旋转地安装用于输送吹塑薄片的偏转辊和用于沿着其间限定的传送平面从偏转杆接收吹塑薄片的空气转动杆。 吹制片材绕过空气转向杆的周边部分,从而限定了至少一个空气转向杆的支撑弧形区域,吹塑片材围绕该支撑弧形区域被支撑。 空气转向杆具有设置在支撑弧区域中的排气口,通过该空气排出口压缩空气被喷射以支撑吹塑片材。 空气转动杆具有限定曲率平面的弧形轴线,其被定向为使得周边部分呈现出凹部表面,空气出口开口设置在该凹面中并与吹塑片材相对。
