  • Publication number: 20090260301
    Abstract: The outstanding tensile strength of some materials are used in compression applications by using air pressure to supply the outward force on an enclosure and by using interior tension members to maintain the geometry of the air-pressurized structure. The air pressure on each face of the structure is balanced by the tension in the tension members. Due to the high modulus of the tension members, the air-pressurized structures are very rigid. It is the air pressure that actually supports any load placed on the structure, but it is the tension members that maintain the geometry when the load is removed, and the strength of the tension members determine how much air pressure can be sustained. The mass of tension material required in such a structure is roughly equivalent to the amount of filament material required in a cable to support the same load. The Compressed-air Rigid Building Blocks can be stacked like bricks to form strong, lightweight walls, buildings, towers, and other structures.

    Abstract: A wire guider includes a guiding unit having an inner path extending along the running direction of the wire to guide the running of the wire and an air supply unit for supplying air into the inner path to form a spiral air flow having a current rate faster than a running rate of the wire between an outer surface of the wire and an inner surface of the inner path. Wire Vibration resulting from a thrust force of mill rolls can be damped to more stably carry out one-direction running of the wire and minimize contact between the wire and a guide path. This reduces surface defects of the wire and abrasion of the guide system and protects a sensor unit from damage.

  • Publication number: 20040035539
    Abstract: A method and an apparatus for web threading in a drying section of a paper machine or the like. A leader (24) and a so called run-down strip are formed by cutting in the web coming to the drying cylinder in the drying section. An underpressure box (18) is arranged at the opening gap between the drying cylinder (14) and the drying wire, on that side of the wire which is away from the web, whereby this box can direct against the web an underpressure which is controllable in the machine's cross direction. The underpressure box creates an underpressure region (34′) between the leader and the underpressure box, the region having an underpressure p1 at the detachment point, i.e. in the area where the wire is detached from said drying cylinder (14), which underpressure is sufficient to detach the leader from said drying cylinder.
