  • Patent number: 7691224
    Abstract: A thermal polymer-bonding method includes initially placing into contact certain polymer-based first and second solid media at a first junction. A first superficial portion of the first solid medium is liquefying through the application of thermal energy to the first junction. The liquefied first superficial portion is superficially or topically applied to the second solid medium whereafter the topical application may be solidified via the action of cooling or withdrawal of thermal energy from the first junction. The solidification of the liquid elements, having maximized surface area contact between opposing media, bonds the first solid medium to the second solid medium. A third polymer-based solid medium may then be placed into contact with the first solid medium at a second junction, whereafter certain select second superficial portions of the first and third solid media may be liquefied, and re-solidified to bond the third solid medium to the first solid medium.

To do this, the method of the invention consists in spreading conductive particles (13) on a medium (11), the particles being directed by prior magnetization along an inducing magnetic field and being embedded in a binder (12). The coating apparatus for implementing the method of the invention comprises means (10, 15) for feeding the medium (11) onto a conveyor (20), means for applying a main binder (12) via presser rollers (40) and via at least one nozzle (30), said means being coupled to heater means, a tank (50) of particles (13) coupled to a duster (51) for dispensing the fill of particles, means for spreading the fill of particles within the main binder, electromagnetic means (60) for producing an anisotropic magnetic field for magnetizing the particles, a sprayer (80) for depositing an additional binder, dryer means (100), demagnetizer means (110), and winder means (120).

  • Patent number: 6998000
    Abstract: A method of adhesion inhibiting generation of bubbles is provided. Heating, evacuation and centrifugal degassing are performed on an adhesive 37 disposed in an adhesive container 30 to semi-harden the adhesive 37, then a semi-hardened adhesive is discharged as disposed in the adhesive container 30 to mount a chip. Removal of bubbles is efficiently performed since semi-hardening and degassing are simultaneously performed. Further, no defective product is produced even if a working process is stopped since no process for semi-hardening a discharged adhesive exists.

  • Patent number: 6991832
    Abstract: In order to produce a fusible interfacing, dots of a hot-melt polymer are deposited on the right side of an interfacing support selected from textile and nonwoven supports and the wrong side of the interfacing support undergoes electron bombardment. The dots of hot-melt polymer are based on at least one functionalized polymer comprising functional groups that can react with free radicals generated by the action of an electron bombardment and/or which are themselves generators of free radicals under the action of an electron bombardment. The penetration depth of the electrons into the polymer dots is adjusted to obtain self-crosslinking of said functionalized polymer over a limited thickness e with respect to the mean thickness E of the polymer dots. The functional groups preferably comprise functions containing an ethylenically unsaturated bond, for example of the acrylate, methacrylate, allyl, acrylamide, vinylether, styrene, maleic or fumaric type.

    Abstract: Methods of manufacturing composite webs including a substrate with one or more reinforcing discrete polymeric regions located on or within the composite web are disclosed. Molten nonelastomeric thermoplastic material of the discrete polymeric region is forced against the substrate by a transfer roll. If the substrate is porous, fibrous, etc., a portion of the nonelastomeric thermoplastic composition may infiltrate the substrate and/or encapsulate fibers of the substrate.

  • Patent number: 6936125
    Abstract: A method of securing an elastic strand to a flat substrate or sheet of material moving the elastic strand and the sheet in a converging manner from a first position in which the elastic strand is spaced from the sheet to a second position in which the elastic strand contacts one surface of the sheet. A filament of adhesive is dispensed onto the strand in a pattern configured with adhesive masses coupled by thinner filament sections. The adhesive masses are contacted with the strand when the strand is in the first position. The strand is bonded to the substrate with at least the adhesive masses.

  • Patent number: 6899775
    Abstract: This invention relates to the printing of a substrate having a pre-printed “print pattern” with a “design layer” of ink where there is differential adhesion within and without the print pattern. The print pattern is receptive to an ink, and the design layer ink forms a durable image material with good bond to the print pattern, but the ink does not form a durable image material on the portions of the substrate outside the print pattern. The design layer ink is a UV-curable ink, and the print pattern may have a higher surface energy than the portions of the substrate outside the print pattern.

    Abstract: A high speed embossing and adhesive printing process using a first and second embossing rolls having complementary embossing pattern disposed thereon. A web of sheet material is placed in contact with an adhesive applied to the first embossing roll. The adhesive forms an adhesive pattern on the web of sheet material in register with the first embossing pattern of the first embossing roll. The web of sheet material is then passed between the first and second embossing rolls which emboss the web with the complementary embossing pattern.
