Longitudinal bead molding

An edge-beaded fastener product such as a cushion cover tie-down has a molded profile bead secured to and extending along a flexible strip adjacent a longitudinal edge of the strip. The profile bead has a shoulder or an inboard sidewall extending away from the strip, such as for retaining a clip or hog ring. The flexible strip may have a reinforced region, inboard of the shoulder, in which resin contiguous with resin forming the profile bead encapsulates surface features of the strip. The product is made by molding resin directly onto the strip. Multiple lanes of resin may be molded on a single substrate, which is severed to form individual strips with severed, exposed strip edges.

FILL PACKAGING METHOD AND FILL PACKAGING MACHINE FOR LIQUID PACKING MATERIAL

In a method for forming a lateral sealed portion, a liquid packing material can be filled without biting bubbles, granulates and so on included in the liquid packing material into the lateral sealed portion. In a method for forming a lateral sealed portion with a pair of lateral sealing rolls after a packaging film fed and run is folded at its central portion and a vertical sealing is performed at their side edge parts to shape into a cylindrical form and a liquid packing material is filled into an inside of the cylindrically formed packaging film, at least a folded side part of the cylindrically formed packaging film is pushed with a pushing means arranged between heat sealing bars located at equal intervals in a circumferential direction of the lateral sealing roll and the lateral sealed portion is formed at a pushed position with the pair of lateral sealing bars.

METHOD AND APPARATUS FOR APPLYING ANNULAR DOSES
20170239848 · 2017-08-24 ·

A method and an apparatus for forming annular doses provides a flow of plasticised material supplied by an extruder which passes through a channel that is first cylindrical and then annular. The material exits from an annular outlet in front of which a cutting element passes that separates an annular dose of material. The dose is deposited on a surface of a capsule having a capacity to adhere to the dose that is greater than the cutting element. The surface and the cutting element are distanced from one another in such a manner that the annular dose remaining adhering to the capsule is detached from the element. Detachment can be promoted by a flow of air.

Inflatable bladders for use in footwear and other articles of manufacture

The present invention is a method for manufacturing inflatable bladders for use in articles of manufacture. The method includes the steps of providing a first polymer film, applying a curable release coating to the polymer film in a pattern that corresponds to the configuration of the inflatable bladder, curing the release coating to the first polymer film, providing a second polymer film with the first polymer film to form a layered element such that the release coating is disposed between the polymer films, positioning the layered element between two plies of material, applying heat and pressure to adhere the polymer films together except in the area where the release coating has been applied to form an inflatable compartment surrounded by a sealed perimeter, and removing the plies of material from the adhered first and second polymer films.

11426918 · 2022-08-30 ·

The invention concerns a machine for manufacturing plastic items comprising, in series, along the manufacturing line: a rotatable roll (1) of plastic material in the form of at least one strip; a shaper (4) for forming tubes from said strips and means (5) for longitudinally welding said tubes; means (6) for cutting the tubes transversely, arranged so as to form tube sections (10); means for transferring and depositing said sections in holding and moving means; an oven (8) in which said tube sections move; a first turret (9) supporting moulds; means for processing the tube sections in the first turret; means for blowing a pressurised fluid into the moulds; a second turret (14) for discharging the bottles from said moulds.

Laminated, blow-molded container and process for forming one or more air intake holes

Disclosed is a process for forming one or more air intake holes wherein the punch-cutter to be used has a cylindrical blade at the tip, and also has a hooking portion or portions, which is/are disposed on an inner peripheral surface of the cylindrical blade and which performs a function of hooking into a portion of the outer layer that has come inside the cylindrical blade to prevent the cylindrical blade from slipping out of that portion of the outer layer at a time when the cylindrical blade is moved backward, the cylindrical blade is pressed forward until the blade edge comes to a position close to the outer layer, and at this position, the outer layer is not yet cut out completely, but there remains a circular uncut portion ahead of the blade edge, then, the cylindrical blade is moved backward.

METHOD OF MANUFACTURING INTERMEDIATE PRODUCT OF AIRCRAFT PART AND AIRCRAFT PART

A first laminated body is worked to form a second laminated body, the first laminated body being formed by laminating prepregs including reinforcing fibers and resin, the second laminated body including a flat portion and a wavy portion, the flat portion being located at at least one of side edge portions of the second laminated body, the wavy portion being located at a portion adjacent to the side edge portion and extending along a longitudinal direction. An intermediate product is formed from the second laminated body by a forming die such that the flat portion becomes a bent portion that is an inside portion whose circumferential length is shorter in a curved portion, and the wavy portion becomes a bent portion that is an outside portion whose circumferential length is longer in the curved portion.

Implantable medical device with varied composition and porosity, and method for forming same

A method for forming a thermoplastic body having regions with varied material composition and/or porosity. Powder blends comprising a thermoplastic polymer, a sacrificial porogen and an inorganic reinforcement or filler are molded to form complementary parts with closely toleranced mating surfaces. The parts are formed discretely, assembled and compression molded to provide a unitary article that is free from discernible boundaries between the assembled parts. Each part in the assembly has differences in composition and/or porosity, and the assembly has accurate physical features throughout the sections of the formed article, without distortion and nonuniformities caused by variable compaction and densification rates in methods that involve compression molding powder blends in a single step.

COMPOSITE WING STRUCTURE AND METHODS OF MANUFACTURE

A method of manufacturing a tiltrotor wing structure including providing a spar mold having a plurality of bores extending from an exterior surface of the mold to an interior surface of the mold, the plurality of bores corresponding to a plurality of primary coordination holes in a spar member, the spar mold having a periphery defined by a top edge, a bottom edge and outboard ends; selecting a plurality of resin impregnated plies to ensure that the plies continuously extend beyond the periphery of the spar mold; laying the plies in the spar mold; curing the plies in the mold to form a cured spar member that extends beyond the periphery of the spar mold; and accurately drilling a plurality of primary coordination holes in the cured spar member in the spar mold using a tool positioned in the plurality of bores.

MANUFACTURING FIBER-REINFORCED THERMOPLASTIC CONCENTRATES
20220266550 · 2022-08-25 ·

A fully impregnated fiber-reinforced thermoplastic granule includes a fiber core impregnated with a thermoplastic resin and coated with the resin and subsequently polymerized to form a thermoplastic. The granule is formed in a continuous process including a continuous fiber strand being coated and impregnated with a thermoplastic resin, curing the thermoplastic resin, and cutting the fiber and thermoplastic into granules of a desired length. The continuous process results in a uniform, fully impregnated fiber core in the granule which results in a longer reinforcing fiber for added strength in subsequently produced products formed from the granules.
