  • Patent number: 8231757
    Abstract: A method of manufacturing laminated bamboo sliver lumber comprises steps of: preparing bamboo slivers; performing moth-proofing, mildew-proofing, and antiseptic treatments to the bamboo slivers and then drying the bamboo slivers to a moisture content of about 6-15%; machining each dried bamboo sliver to a thickness of about 0.5-3.5 mm (0.02-0.14 in) and a width of about 5-22 mm (0.20-0.87 in) and then dehumidifying the machined bamboo slivers to a moisture content of about 3-10%; applying a glue to the bamboo slivers by glue-coating or “immerging” process, in which a ratio of the glue to an absolute dry weight of the bamboo slivers is about 3-16%; and arranging the glued bamboo slivers with their “width” direction consistent with the “vertical” direction and then pressing the arranged bamboo slivers and curing the glue under a “side” pressure of about 3-15 MPa (0.44-2.18 ksi) and a “top” pressure of about 1-6 MPa (0.15-0.87 ksi) so as to form the laminated bamboo sliver lumber.

  • Patent number: 8202390
    Abstract: We disclose a method for the production of a diaper, with an absorbent body, a front portion, a back portion and a crotch portion arranged in-between, and with lateral back portions bilaterally attached to the back portion and lateral front portions bilaterally attached to the front portion, which extend in transverse direction of the diaper beyond the main body, and are spaced apart in the longitudinal direction of the diaper, where the lateral back and front portions may be detachably connected to one another to apply the diaper, where a separation process including the lateral back portion, the main part and the lateral front portion is implemented to contour the bilateral leg opening areas of the diaper, so that a connected offcut is formed, characterized in that the offcut is gripped and conveyed away by a transfer roller having pin-, needle-, knob-, hook- or barb-shaped mechanical elements protruding from its surface.

  • Patent number: 8172977
    Abstract: The present invention provides a process wherein a rotary knife or die, with one or more cutting edges, turns against and in coordination with a corresponding cylinder to create preferably trapezoidal ears. Ear material is slit into two lanes, one for a left side of a diaper and the other for a right side of a diaper. Fastening tapes are applied to both the right and the left ear webs. The ear material is then die cut with a nested pattern on a synchronized vacuum anvil. The resulting discrete ear pieces however, due to the trapezoidal pattern of the ears, alternate between a correct orientation and an incorrect (reversed) orientation. The reversed ear is required to be rotated 180° into the correct orientation such that the ears and associated tape present a left ear and a right ear on the diaper.

  • Patent number: 8056455
    Abstract: A method and apparatus for producing shaped articles from a web material is disclosed. The apparatus generally includes a rotary cutting roller, preferably including indicia on an end surface, and an anvil roller operating in cooperating rotational movement with the rotary cutting roller. The apparatus die cuts web material into predetermined shapes. The apparatus further includes at least one sensor for detecting rotational movement of the rotary cutting die by way of the indicia on the end surface of the rotary cutting roller. The information from the at least one sensor and an encoder is processed and translated to drive means to thereby corrects variation in web alignment relative to the rotary cutting roller. The adjustment of the rotary cutting roller of the present invention allows the rotary cutting roller to cut within a high degree of accuracy and precision.
