  • Patent number: 8226789
    Abstract: A protective cover for a golf club, such as a driver or wood, is disclosed that remains in place during play to prevent scuffing, scratching, and the like of the surface finish. The golf club includes a head having a striking face portion and a non-planar body portion, and a shaft extending from the head. The protective cover includes a one-piece continuous polymeric film that closely conforms to the shape of at least a portion of the non-planar body portion of the golf club head, such as the entire crown, and a layer of adhesive adhering the polymeric film to the club head. The polymeric film preferably does not cover the face portion of the golf club head so that it has minimal impact on the performance of the golf club. A method of applying the protective cover to the club head is also disclosed.

  • Publication number: 20120100353
    Abstract: Provided is a high-shielding reflective film, and its manufacturing method. This film is fabricated from an optical reflective film and a polarizer. The optical reflective film and the polarizer are combined by a means of a specific scheme. The optical reflective film is formed by stacking multiple layers of dielectric optical interference films with different materials. The optical reflective film particularly applies a principle of optical interference to reflect the most of the incident light, and allow some transmission. The polarizer is to absorb half of the incident light, and allow the other half to pass through. Since the characteristics of reflection between the reflective film and the polarizer are different, the reflectance difference therefor may increase. By which, the high-shielding reflective film achieves a one-way mirror with anti-peep effect since it substantially increases the reflectance difference among the incident lights from the various directions.

  • Publication number: 20120037300
    Abstract: A laminated web from which diaper closure elements may be punched is made by first applying at least two pairs longitudinally extending and transversely spaced bend-resistant strips to a first longitudinally extending nonwoven tape. Then a respective longitudinally extending strip of an elastically stretchable polymer is applied to the first nonwoven tape between each of the pairs of the bend-resistant strips with the polymer strip partially overlapping both of the bend-resistant strips of the respective pair. A second longitudinally extending nonwoven tape that covers and extends transversely to both sides of the polymer strip is applied over the bend-resistant strips and the polymer strips to form a laminate with the polymer strip between the first and second nonwoven tapes.

  • Patent number: 8114235
    Abstract: A method of continuously making a disposable pants-type diaper includes feeding first and second webs in a machine direction and bonding the first and second webs together to obtain first composite web. From the first composite web, a substantially circular section defined between each pair of the adjacent chassis in the middle region as viewed in the cross direction is clipped out to obtain a second composite web. The second composite web is folded in two and halves of the second web facing each other are locally bonded together by bonding agent to obtain a third composite web. The third composite web is provided on both sides of a cutting line extending in the cross direction with seal regions to obtain a fourth composite web and finally the fourth composite web is cut along the cutting line to obtain the individual pants-type diapers.

  • Patent number: 8114236
    Abstract: Disclosed is a method of continuously making a disposable pants-type diaper having a body waste receiving pocket. A first web is continuously fed in a machine direction and a second web is continuously fed onto the first web and is folded back onto itself in a cross direction and locally bonded together along opposite edges thereof to obtain a third web. The third web is superposed on the first web and then the first web and the third web are bonded to each other to obtain a first composite web. From between the adjacent chassis in a second composite web defined by the first and third webs, substantially semicircular web pieces are clipped out to obtain third composite web on both sides of a cutting line to obtain a fourth composite web which is cut along the cutting line to obtain the individual pants-type diapers.

  • Publication number: 20120034436
    Abstract: The invention relates to a method for producing nonwoven/film laminates for personal hygiene articles, from an initial film web consisting of a thermoplastic polymer and an initial nonwoven web. According to said method, the initial film web and the initial nonwoven web, whose melting point lies above the crystallite melting point of the polymer, are heated to a temperature that exceeds the crystallite melting point of the polymer and lies below the melting point of the initial nonwoven web. The laminate is then guided through a cooled nip and is cooled to a temperature that lies below the crystallite melting point of the initial film web. The invention also relates to laminates that can be produced by said method.

  • Patent number: 8100173
    Abstract: A continuous method for producing incontinence articles in the form of pants for receiving body excrements utilizes crotch sections comprising absorbent bodies and having leg cut-outs formed by a first contour cut. Two partial webs are joined to the crotch sections in such a fashion that one end of the crotch sections overlaps one partial web in a longitudinal direction transversely to the machine direction, and the other end thereof overlaps the other partial web, and the crotch sections are disposed at a separation from each other in the machine direction. A second contour cut is performed that includes the partial webs on their mutually facing edge sections for forming substantially curved leg cut-outs. The article is then folded and the partial webs are joined transversely to the machine direction at a separation from each other for forming side seam areas of the incontinence article to be produced.

    Abstract: A new liner and method of forming a liner for use in lining the junction between a main pipe and a lateral pipe are provided. A liner tube is joined about one end to a liner member about an aperture in the liner member. A liquid thermoset adhesive is applied around a junction formed between the liner tube and the liner member on a resin impermeable coated side of the liner tube and the liner member. The thermoset adhesive is not affected by temperature changes present during an exothermic reaction when the resin impregnated liner tube and liner member are cured and hardened.

  • Publication number: 20110303352
    Abstract: Sliced specimens can be automatically and continuously prepared and burdens of an operator can be reduced while accuracy required for the sliced specimen is maintained. The sliced specimen is prepared by relatively moving a specimen block transfer section and a cutter, and when a slicing operation to adjust the height position of the specimen block is continuously performed so that the cutting surface of the specimen block is located at a sliceable position, the cutter is moved so that a contacting area of a blade edge of the cutter that firstly contacts the specimen block after the height position adjustment is sequentially changed, every time previously set number of times of slicing operation is completed. Thereafter, the height position of the blade edge of the cutter after the change is measured by a detector, and based on the measurement information of the detector, the sliceable position is corrected and the slicing operation is resumed.
