Abstract: The present invention relates to webs made of cellulose fibers admixed with thermobonding fibers, wherein the web surfaces are sealed to a greater or lesser extent by adding thereto a binder in modest amounts. The binder is applied without any attempt to provide deep penetration of said binder into the web material. By applying the binder in the form of a foam, a minimum of binder is required to provide bonded webs exhibiting minimal linting.

Abstract: Process for manufacturing molded articles made of plastics, cellulose, pulp or wood fibers with cavities, in particular composite parts for light weight construction, by means of tool parts, including the following process steps: a) matrix layer is provided at pre-selected locations with inserts containing gas-creating substances or blowing agents and b) these inserts are activated to create gas in tool parts and thus expand the matrix material. Also disclosed are gas-creating insertion elements for use in the process and made of gas-creating blowing substances enclosed in gas-proof sheaths or inserted into the matrix material in order to form locally limited areas. This process allows the production of particularly light and at the same time solid tool parts, in particular composite parts for light-weight construction.

Abstract: A method for positioning side panels during manufacture of a pant includes positioning the side panels within fluid flow devices. The side panels can move parallel or perpendicular to a pant transport plane as the pant is transported in the machine direction and the side panels reside within the fluid flow devices. The side panels can include refastenable fastening components. The method and apparatus can move the fastening components closer together in the cross-machine direction while the side panels reside within the fluid flow devices.

Abstract: A method for manufacturing a prepreg in which a reinforcing substrate is impregnated with a thermosetting matrix resin. In the method, the reinforcing substrate is moved in a traveling direction. The thermosetting matrix resin is supplied to an outer circumferential surface of a transferring roller. The thermosetting matrix resin which substantially contains no solvent and which is in. a molten state is transferred from the outer circumferential surface of the transferring roller to a first surface of a reinforcing substrate while the reinforcing substrate moves. The thermosetting matrix resin which is transferred to the first surface is forced to permeate through the reinforcing substrate by pressing at least one pressing roller on the thermosetting matrix resin transferred to the first surface while the reinforcing substrate moves. The reinforcing substrate impregnated with the thermosetting matrix resin is heated to semi-cure the thermosetting matrix resin.

Abstract: A pipe lining method is provided for accurately cutting or punching out a pipe liner bag after being lined on an inner wall of a pipe with a good operability while preventing an operation environment from being contaminated. A fluid pressure is applied to act on a pipe liner bag introduced in a pipe to press the pipe liner bag onto the inner wall of the pipe. A thickness reducing member is brought into contact with the outer surface of the pipe liner bag to partially reduce the thickness of the pipe liner bag. A predetermined pipe lining operation with the above state maintained. Then, an external force is applied to a thickness reduced portion of the pipe liner bag to break the portion.

Abstract: A window glass of a vehicle, to which a hot melt adhesive agent is applied, is pushed while the window glass is held by a jig which is mounted on a robot. An allowable range of temperature of the adhesive agent is set between an upper limit and a lower limit. The upper limit is one at which the adhesive agent comes to have such a holding force above a predetermined value as to prevent deviation of the window glass. The lower limit is one at which a compression reaction force when a bead of the adhesive agent applied to the window glass is crushed to a predetermined thickness becomes smaller than a predetermined value. The adhesive agent is applied to the window glass at such a temperature that the temperature thereof at the time of completion of pushing of the window glass falls within the allowable range. The apparatus for mounting the window glass has a jig for the window glass which is provided at a front end of a robot arm.

Abstract: A method and apparatus for manufacturing prestressed piezoelectric actuators which maximizes output, and increases the precision and efficiency with which the multi-layer actuators are made. Individual layers of the piezoelectric actuators are automatically stacked and registered with respect to each other within press members prior to bonding the layers to each other with a thermoplastic adhesive. Compressive force is applied while heat is conductively transferred from a heating element to the actuator in order to raise the temperature of each of the layers above the melting point of the thermoplastic. The temperature of the heating element is then decreased until the temperature of the actuator layers drops to below the melting point of the thermoplastic adhesive, thereby bonding the layers. Compressive force is then released, and the actuators are removed, further cooled and polarized.

Abstract: Composites of paper and bioriented polyester plastic film are made by passing a web of paperboard and a web of plastic film, with a layer of extruded molten polymer impregnating and bonding agent between the webs, through a nip. The process involves controlling one or more of the speed of the webs, the temperature of the molten polymer, the pressure or spacing of the rolls at the nip, and the rate of extrusion, relative to the porosity and surface characteristics of the paper web such that a portion of the molten polymer impregnates partially into and becomes part of the paper web and a substantial portion lies outwardly of the surface of the paper web and solidifies to form a new surface to which the film is bonded and which it is supported clear of the paper surface. The molten polymer may be polyethylene or an ethylene acrylic acid copolymer. These composites are useful in forming corrugated structures which may be used for baking in convection ovens.

Abstract: A method and apparatus for aligning discontinuous fibers (F 101, 212) is described. A feeder apparatus (20, 120, 220, 220A) is used to align the fibers in a horizontal plane for feeding to the aligning apparatus (40, 140, 240, 240A) providing an electrical (E) field to orient the fibers in one preselected direction. A support or conveyor (70, 170, 270) receives the aligned fibers. The method and apparatus provides composite products having improved physical properties because of the alignment. The fibers can be of different lengths and a mixture of different types to make composites with controlled microstructure and properties. The composite materials can be in the form of non-woven, discontinuous fiber reinforced thermoplastic stampable sheets with controlled fiber orientation distribution. The composites are useful for a variety of goods.

Abstract: A separator sheet is formed of a plastic material and has a number of ribs formed on one side thereof. The ribs extend in the direction in which the separator sheet is fed. The sheet is overlaid with a glass mat, and a laminated member obtained thereby is moved into the region between a pair of driving rolls. After being sandwiched by the driving rolls, the laminated member is fed into an envelope apparatus. In an adhesive coating step, a hot melt type adhesive is coated on one side of the glass mat. The adhesive is coated at portions C corresponding to the base sections between the ribs of the sheet, in such a manner that the coated adhesive forms a line extending in the longitudinal direction of the glass mat. In a stacking step, the sheet and the glass mat are stacked one upon the other.
