摘要： A guide assembly for blown plastic tubes to guide and support the tube after its extrusion from a die consists of a frame carrying a plurality of pairs of vertically-extending members distributed circumferentially around the tube. Each of the vertically-extending members carries a plurality of vertically-spaced parallel radially-inwardly-extending arms. Each arm of one vertical member of the pair cooperates with a respective arm of the other member of the pair, each cooperating pair of arms having a flexible wire support member extending between these ends, the wire engaging the tube and conforming to its circumference. As the tube diameter decreases the arms are moved simultaneously radially inward by opposite rotation of the respective vertical members, whereupon the wire conforms to the new reduced diameter, and vice-versa. The actual contact of the support member with the tube is by side-by-side cylindrical rollers (e.g. of nylon) threaded on the wire. An additional support means may be provided that engages the center of the guide wire and, in addition to preventing downward sagging, automatically presses it radially inward with an increasing force as the tube diameter is decreased.

摘要： Air ring for cooling a hot extruding tube of plastic film in which a lubricating air bleed port communicates with air from the air ring plenum independent of the cooling air flow path. The bleed port communicates with a bleeded air passage that extends to an annular lubricating air outlet positioned in advance of a guide surface that precedes the cooling air outlet. In an exterior air ring a valve arrangement limits the bleeded flow to the minimum desired.

摘要： Disclosed is a method of making a multi-level assembly of flexible nets for supporting flowers to allow them to grow in straight, upstanding shape through the mesh openings of the nets which are raised progressively to different levels of height above a flower bed in accordance with the growth of the flowers. A plurality of nets are laid one upon another with their mesh openings substantially correctly aligned with one another and placed on a frame in a vertically zigzag folded pattern. Then, the nets are, together with the frame, immersed in a bath of a heating medium, such as hot water, to allow the nets to undergo thermal contraction, whereby the mesh openings of the nets are correctly with one another. The nets are, together with the frame, removed from the bath and allowed to cool. Then, the nets are removed from the frame with their folded shape substantially in order.

摘要： A method of coating a fabric material and calendering the material while longitudinally and transversely tensioning the material, the coating being synthetic and being applied to one side of the material, and being heated in a curing oven. Then applying more synthetic material of a similar type to the calendered and heated material and then passing it through another oven and calendering it again before the tensioning is relaxed.

摘要： An apparatus for the precision positioning of electrostatic pinning means. The electrostatic pinning means, which significantly improves pinning of a thermoplastic polymeric film cast upon a moving surface, by electrostatic force, is precisely positioned, in relation to an extrusion means and the moving surface, by means of the precision positioning apparatus. The apparatus includes a frame moveable in vertical and horizontal directions. The apparatus further includes the pinning means and support means, connected to the frame, for holding the electrostatic pinning means. Horizontal and vertical adjusting means comprising horizontal and vertical actuating means connected to horizontally and vertically moveable means responsive to the horizontal and vertical actuating means, respectively, are connected to the frame to permit separate horizontal and vertical movements to precisely position the electrostatic pinning means. Horizontal and vertical precision control means are additionally provided, on the moveable frame of the apparatus, to insure that no skewing occurs during horizontal and vertical movements actuated by said horizontal and vertical adjustment means.

摘要： A woven cloth of flexible material is masked to expose only longitudinal spaced stripes. A plastic polymer is applied to the exposed material. The striped cloth is draped over spaced supports that are transverse to the stripes. Depressors are applied to the cloth between the supports so that the cloth is substantially sinusoidal in crosssection. The cloth is cured to harden the stripes so that the cloth is still flexible in one direction but only slightly flexible in the other. The cloth is warped, bent or otherwise shaped as desired for application to it of laminar sheets of cloth, metal or wood, then the core and the laminates are joined, impregnated and cured to a rigid structure of desired configuration and high strength to weight ratio.

摘要： Apparatus for air-cooling blown tubular thermoplastic film downstream of a position where the film has already solidified comprises a ring having air outlets directed onto the tubular film, the ring comprising a plurality of blow pipes which are pivotally interconnected in pairs at adjacent ends and hinged at their other ends to holding elements which are radially adjustable with respect to the tubular film. The hinge axes at the holding elements are disposed so that the blow pipes form a uniform polygon and the lengths of the individual pipes is such that, when the holding elements are at their radially outermost adjustment, the pipes extend in an obtuse angled zig-zag line circumferentially of the tubular film.

摘要： An extruder continuously forms a sheet that is intermittently supplied to an intermittently activated, in-line processing station, e.g., a thermoformer. The sheet is supplied to the processing station via a variable accumulator that is adapted to have a rest state immediately prior to the sheet being supplied to the processing station. The extruder includes a screw for feeding material to sheet forming dies at a mouth of the extruder, as well as rolls for taking the sheet material away from the extruder mouth. The rest state time is measured to derive an indication of the take-away speed of the sheet from the mouth relative to the speed with which the sheet moves through the intermittently activated processing station. The activation rate of the processing station is measured, as is the thickness of the sheet after it has reached a set state, prior to passing through the accumulator. In response to the three measurements, the screw and line speeds are controlled so that the sheet thickness is maintained approximately at a setpoint value, and sufficient material is always available to the processing station, and excess material is prevented from piling up at the accumulator.
