摘要： Gusset boards of a blown film extrusion apparatus have nose portions that can be positioned in the path of a tube of blown film traveling between the nose portions where the nose portions engage with opposite sides of the tube of blown film and form gussets in the tube of blown film. The nose portions of the gusset boards can also reduce their width dimensions which enables the nose portions to be moved away from the path of blown film traveling between the gusset boards when gussets formed in the opposite sides of the tube of blown film are not needed.

摘要： Apparatus for conveying continuous collapsed film includes a guidance arrangement receiving the continuous collapsed film, the guidance arrangement including at least one guide roller and at least one turning bar for guiding the film. The at least one guide roller changes the direction of the film 180 degrees, and the at least one turning bar changes the direction of the film 180 degrees. A conveyor belt travels the same speed as the film and the conveyor belt and the film loop over the one turning bar in superimposed relationship with the conveyor belt being between the at least one turning bar and the film such that the conveyor belt carries the film during the looping over the at least one turning bar.

摘要： Apparatus for effecting gauge distribution in flattened tubular plastic film has a collapsing device for collapsing upwardly vertically moving expanded tubular plastic film to a two layer flattened condition, a first motor for rotating the collapsing device through 180.degree. in each direction from a neutral position, a first horizontal film direction reverser secured to the collapsing device for rotation therewith a first horizontal turning bar located above the collapsing device and extending substantially through the central axis, a second horizontal film direction reverser, and a second horizontal turning bar located about the first turning bar. A second motor arrangement simultaneously rotates the first turning bar through 135.degree. in each direction from a neutral position, the second film direction reverser through 90.degree. in each direction from the neutral position and the second turning bar through 45.degree. in each direction from the neutral position simultaneously with the 180.degree. rotation of the collapsing device and first direction reverser by the first motor, and thereby distributes gauge variations in the two layer flattened film leaving the collapsing device across the width of the flattened film.

摘要： A substantially rigid thermoplastic pipe for repairing a pipeline by installing the thermoplastic pipe in an existing underground pipeline, such as a service lateral, having access from only one end and a bend along its length is provided. The thermoplastic pipe may be manufactured in reduced form so as to have a memory for the reduced form, is heated to make it pliable for installation, and is pulled into the lateral from the access opening using a cable-and-pulley arrangement anchored temporarily at the intersection of lateral and main pipelines. When installed in a lateral, it is rounded and cooled in its rounded shape by passing steam under pressure through passages along the folds of the pipe while its leading end is restricted.

摘要： A thin, flexible tubular membrane provides a heat containment tube for inserting into and inflation within an underground conduit to be repaired. Folded rigid thermoplastic pipe is inserted into the tube while not and flexible. The tubular membrane is pressurized to exclude unwanted fluids from within the existing conduit. Hot steam is injected into the tube to heat the pipe full-length externally and internally until flexible. The pipe is then rounded and expanded against the walls of the conduit with the tube therebetween. The rounding and expanding of the pipe is carried out progressively by moving a plug through the pipe and by injecting hot steam under pressure behind the plug.

摘要： An off-drawing apparatus for tubular webs of plastic film produced by an extruder with a fixedly disposed blow head includes a lay-flat apparatus for the tubular web delivered with an expanded round cross section, and a stationary conveyor for carrying off the flattened tubular web to a likewise stationary winding apparatus. Between the lay-flat apparatus and the conveyor there is disposed at least one pulley roll and one overturning bar for turning the tubular web 180.degree. with simultaneous change of direction, which, like the lay-flat apparatus, are supported in an apparatus frame for pivoting reversingly in a horizontal plane about the axis of the delivered tubular web. The lay-flat apparatus, the pulley roll and the overturning bar are held for their reversing pivoting movement on swivel rings disposed one over the other and supported directly on one another through interposed rolling bodies which form together a swivel ring stack rotatably mounted in the apparatus frame and compressively stressed, whose inside diameter is at least equal to the maximum working width of the apparatus.

摘要： In one embodiment, the oscillating pinch roll assembly or web handling apparatus includes a rotatable spindle having an input which accepts the tubular web. A pinch roller is mounted at the input. A plurality of rollers are circumferentially disposed around the pinch roller and the axis of rotation of those rollers is parallel to the center line of the tubular web. A turning bar is disposed in the interior of the spindle and turns the flattened web exiting the pinch rollers 90 degrees and feeds the horizontal web to a first roller of the plurality of rollers disposed at the periphery of the spindle. The traveling web always passes over this first roller. By rotating the spindle in an oscillatory manner about the center axis of the tubular web, the horizontally traveling, flat web is wound and unwound around the outer periphery of the spindle and is fed to a fixed idler roller.

摘要： The apparatus of the invention provides gauge distribution in extruded plastic tubing, so that a more uniform roll thereof is obtained. The extruded plastic tube, usually blown to increase its diameter and decrease its wall thickness, is collapsed and passed through a diametrical slot in a rotor, which is rotated about a vertical axis so that any non-uniformity in wall thickness of the tube is distributed as much as possible around its periphery. The upwardly-moving tube passes over a skew member which turns it to move horizontally. Two spaced parallel end rollers are provided between one end of the slot and the rotor periphery, and each engages the tube during a respective 180.degree. of rotation to deliver the tube to a fixed roller on the apparatus frame from where it passes to the storage roll. Two deflection rollers are also provided on opposite sides of the slot, and each engages the tube in the rotation of the rotor close to zero and 360.degree. to hold the tube away from the slot and ensure that it does not foul the portion of the tube emerging from the slot. A dancer roll may be provided to maintain constant tension. The tube engaging members may be rollers or hollow bars with air issuing apertures in the surfaces over which the tube passes to form a corresponding air cushion between the tube and the member surface.
