  • Extended couch nip on cylinder former
    Patent number: 7510630
    Abstract: An apparatus for use in a cylinder machine having a shoe with a concavely-shaped pressure surface that forms a substantially mating relationship with a cylinder mould or sieve. The concavely-shaped pressure surface of the shoe increases the amount of wrap that a making fabric has on a cylinder mould or sieve thereby increasing the amount of friction generated between the making fabric and the cylinder mould or sieve. The increased friction results in an improved torque transfer between the making fabric and the cylinder mould or sieve.

    Patent number: 7318796
    Abstract: A two-layer drum cover and a method of producing the same are provided. The two-layer drum cover includes a backing wire constructed of a relatively high grade metal alloy in the warp direction and alternating relatively low grade metal alloys in the shute direction. The two-layer drum cover also includes a face wire constructed of a relatively high grade metal alloy in the warp direction and alternating relatively low grade metal alloys in the shute direction. All the metal alloys used in the face wire have a higher grade than the metal alloys used in the backing wire.
