  • Patent number: 8736458
    Abstract: A system includes a camera, a weigh-in-motion scale, and a processor. The camera is configured to capture one or more images of a vehicle as the vehicle goes over the weigh-in-motion scale. The weigh-in-motion scale is configured to generate one or more weight measurements of the vehicle as the vehicle goes over the weigh-in-motion scale. The processor is operatively coupled to the camera and the weigh-in-motion scale. The processor is configured to determine an acceleration of at least a portion of the vehicle based at least in part on the one or more images of the vehicle. The processor is also configured to adjust at least one of the one or more weight measurements based on the acceleration.

  • Patent number: 6422501
    Abstract: A core infeed apparatus for a surface winder moves an elongated core axially into the winder while an axial line of glue is applied to the core. The core is moved into a space between a pair of rotatable core guides. One of the core guides is rotatable away from the core while the other core guide rotates the core toward a core inserter. The core is transferred to the core inserter, and the core inserter rotates to move the core toward the winding rolls of the rewinder. The position of the glue line is accurately maintained as the core moves to its various positions.

  • Patent number: 6286712
    Abstract: A stack of interfolded sheets is formed from a plurality of groups of interfolded sheets. Adjacent groups are secured or bonded together so that the bottom sheet of each group pulls the top sheet of the next group. In one embodiment of the invention, the strength of the bond is such that when the bottom sheet of a group is withdrawn through an opening in a package for the stack, the bond releases the top sheet of the next group after the top sheet is partially withdrawn through the opening. In another embodiment of the invention, the strength of the bond is such that the top sheet remains secured to the bottom sheet and is completely withdrawn through the opening. The sheets can be secured by an adhesive bond or by a non-adhesive bond.

  • Patent number: 6056229
    Abstract: A surface winder includes first and second winding rolls for winding a web on a center member, a stationary surface spaced from the first winding roll for rolling a center member on the stationary surface, and a pinch pad for pinching the web against a pinch surface upstream of the center member and thereby severing the web. The first winding roll is provided with a high friction surface, and only a short length of web needs to be stretched between the pinch surface and the first roll to tension and sever the web. The severed web is wound on the center member as the center member rolls on the stationary surface.

  • Patent number: 5839688
    Abstract: A method and apparatus for producing a roll or log of bathroom tissue or kitchen toweling with a pattern being repeated between each pair of transverse perforations wherein an extensible web having a pattern thereon repeated at equally longitudinally spaced position is advanced along a path toward a rewinder having a knife-equipped perforator and a cutoff mechanism. A detector senses the position of each pattern and also sensed is the position of the perforation knife with the positions being reported to a controller. The perforation knife is adjusted to insure that each perforation is between pattern positions and the cutoff mechanism is adjusted to stay in time with the transverse lines of perforations to provide a selected count of patterns in each winding cycle.

  • Patent number: 4394409
    Abstract: A composite wood article includes a plurality of four elongated triangular-shaped pieces and opposing pieces are substantially similar in cross-sectional dimensions. They are joined together to form a composite parallelogram in cross-section. One alternative embodiment includes using sector-shaped pieces that have been cut from generally cylindrical logs, while another embodiment includes triangular-shaped pieces cut from readily available rectangular lumber. In the process of manufacturing the composite article, the four triangular-shaped pieces are first machined so they are properly sized and then after the appropriate application of adhesive to the surfaces which will form the connecting joints, the joinder base leg of each triangular-shaped piece is positioned so as to be juxtaposed against the adjacent joinder leg of the next adjacent triangular-shaped piece.
