<p>A flattening and removing device for a plastic tubular film web produced by a stationary film blowing head in a blowing process has two deflecting rollers (34, 38) and two turning bars (36, 40). The first deflecting roller (34) and the squeezing roller (32) are mounted parallel to each other between mounting plates (16) that are rigidly connected to a turntable (20) mounted in turning fashion in the frame (22) floor (24). The second deflecting roller (38) is connected by a support frame to a retainer having ends which are connected to gearwheels in eccentric fashion. The turning bars (36, 40) are each connected by support frames to gearwheels, and the center lines of all the gearwheels are aligned with each other and with an imaginary swivel axis. Thus, the diameter of the turning bars can be increased to the desired degree without impeding the passage of the flattened tubular film when the device is installed.</p> |
