摘要:
A fiber lay-up apparatus and method includes one or more fiber sources from at least one fiber supply wherein a fiber may be fed under tension to provide a pre-stress to the fiber. The fiber lay-up apparatus may include a resin impregnator for impregnating a fiber with a resin. The fiber may be impregnated under pressure to reduce friction, to provide a motive force to move the fiber through the impregnator, or to enhance control over impregnation. The fiber may be shaped by a fiber shaping unit including one or more active or passive shaping members that provide enhanced control over the shape and placement of the fiber as the fiber leaves the fiber lay-up apparatus. A cutting element for cutting a fiber as it is being layed-up may be positioned proximal to the one or more shaping members, and may enable the fiber lay-up apparatus to end the lay-up of one fiber (or set of fibers) and begin the lay-up of a new fiber (or set of fibers) without delay. A UV or other curing element may be provided downstream from the cutting element. A splicing unit may be employed to detect when a fiber supply is exhausted, and may splice a trailing end of an exhausted fiber supply to a leading end of a new fiber supply to provide a continuous (or substantially continuous) fiber feed. The splicing unit may also splice at least one sensor into a fiber being fed from the at least one fiber supply to provide information about the fiber either before, during, or after the fiber is layed-up.

Disclosed is an apparatus of manufacturing a pipe-shaped insulator, wherein a thin fiberglass mat is coated, at a surface thereof, with a binder (adhesive) and is press-wound on a forming roller, so as to manufacture a pipe-shaped insulator having a predetermined thickness and a predetermined diameter. The apparatus includes a mat feeding roller, a plurality of fiberglass mat transportation rollers, a coating roller to coat a binder over a surface of the fiberglass mat, a forming roller on which the fiberglass mat, coated with the binder, is wound in plural times to form a pipe-shaped insulator, a squeeze roller disposed parallel to the forming roller, a pressure regulator to press the fiberglass mat, an encoder to measure a transported length of the fiberglass mat, a cutting unit to diagonally cut the fiberglass mat, a control system, a sensor, and a plurality of drive motors and power transmission members.

A modeling apparatus for producing a model by lamination of sheet material including a support platform which can be raised and lowered, a sheet feed mechanism for feeding sheet material over the platform, a superstructure mounted over the platform, a cutting mechanism for cutting the sheet material to form shaped portions, an adhesive applicator for applying adhesive to the shaped portions, and a control mechanism.
摘要:
A double surfaced adhesive tape comprising an elongated strip (14) of flexible material having a longitudinally extending center portion (20) and longitudinally extending first and second edge portions (22, 24). The center portion is thicker than either edge portion, and each edge portion has one adhesively surfaced side (26, 28) and one side (27, 29) that is not surfaced with adhesive. The adhesively surfaced sides may comprise adhesives having different tack properties from one another. The adhesively surfaced sides of the edge portions face in opposite directions from one another. The double surfaced adhesive tape is made by mounting first and second rolls (66, 68) of tape adhesively surfaced on only one side on respective first and second rollers (52, 54), and winding first and second tape strips (70, 72) from the respective rolls onto a rotating core (74) such that the strips are joined together with their adhesively surfaced sides facing one another and overlapping along a portion of their respective widths.

A tape applicator and mastic dispenser for dry wall taping comprising a holder for a replaceable cartridge, means for forcing mastic material from said cartridge through a discharge outlet onto a tape, tape advancing means for feeding a tape from a supply roll beneath the discharge outlet, a roll for applying a mastic coated segment of tape onto a wall joint and means connecting the roll to the tape advancing means for positioning the roll in retracted or tape supporting position by actuation of the tape advancing means, whereby the pressure roll is retracted as tape is advanced beneath the discharge outlet and selectively positionable in front of the dispenser for supporting and applying mastic coated tape to a wall joint.
摘要:
A system and method for automated application of adhesive, buffer, and/or liner to I-joists, whereby a controlled amount of adhesive, glue, buffer material, and/or a protective liner, are successively applied to the exposed flange of an I-joist. An air-activated side pressure wheel first pushes one flange of an I-joist against an opposing friction-reduced straight edge, then at least one adhesive/glue head extrudes adhesive and/or buffer material onto the opposing exposed flange of the I-joist. An overhead liner applicator may then place a protective liner upon the applied adhesive and/or buffer material. An applicator roller bearing and a pressure roller bearing press the adhesive/buffer/liner to the desired mil thickness, after which the liner applicator cuts the protective liner according to the cut pattern instructions received from a controller. A cooler can be used to cool the adhesive/buffer before release liner application. The system may comprise coordinated mechanical, electrical, and pneumatic components.

A method of reinforcing an embedded cylinder pipe by applying a composite structural reinforcement within the pipe through in situ stratification of at least one band of reinforcement fibers and a resin or a resin including matrix comprising the steps of applying said band onto a contact area on an internal face of said pipe by means of a contacting member; moving said contacting member along an helical path so that said contact area follows said path; moving a main pressing member behind said contacting member along said path, to apply pressure to said band in a main pressure area separated from said contact area.
