Abstract: The invention relates to a process to regulate the film thickness of tubular film manufactured using a film blowing process, wherein the film is laid flat and repositioned using an oscillating take-off unit and subsequently monoaxially oriented in machine direction using an orientation unit. This process produces a film whose thickness profile has as few deviations as possible from the average film thickness across the film width. This result is achieved by setting the film thickness profile of tubular film produced with a film blowing line such that after orientation and as a result of deviations during orientation, a film thickness profile develops that is uniform across the entire film width.

Abstract: A method and portable apparatus to evaluate the planar flatness of a paper sheet comprises a pair of closely spaced horizontal edges secured in relative parallelism. The horizontal edges are separated by about three feet. The horizontal edges define a horizontal reference plane over which a sheet section of paper web is mildly tensioned with the web machine direction of the paper sheet oriented transversely of the edges. Substantially between the horizontal edges but slightly below the horizontal reference by about ⅛ to ½ inch is a comparison line in the form of a wire, for example. A fixture supporting the comparison line provides a plurality of wire-end attachment points. Supporting the horizontal edges are a pair of scissor frames that are held open to a predetermined angle by a compression gusset. Opposite ends of a horizontal edge are secured to respective upper ends of each scissor frame. Against the compression stress on the compression gusset, the scissor frame is drawn by a tensioned guy wire.

Abstract: A rotatable accumulator roll which may move substantially horizontally or vertically is disposed between the die of an extruder and a take-away conveyor to minimize the effects of output surging of the extrudate from the die of the extruder in order to maintain substantially the dimension of the extrudate as delivered to a constant speed take-away conveyor. Variable force is applied to the roll to maintain tension on the extrudate.
