Method and apparatus for applying a material to a high-speed broadband

摘要

A method of manufacturing a strip (3) having a pattern (5) applied additive material, the method comprising the steps of: preparing a first fiber suspension and liquid material; contribution of the first suspension to a mobile mesh fabric (6) having a longitudinal direction, a mesh fabric transverse to the longitudinal direction, and a nominal linear velocity in the longitudinal direction (16); drain liquid from the first suspension through the mesh fabric to form a mobile fibrous web; preparing a second suspension of the additive material; depositing transverse bands (5) of the additive material on the suspension in the band (3) fiber from a reservoir (30) (30 ') of a distribution device through at least one orifice (44) on a tape (32 ) continuous dispensing device, and move the tape (32) continuous with a speed nominal band having a velocity component in the direction (16) longitudinal virtually the same as the nominal linear speed: characterized by operating at least one of a plurality of devices (10, 10 ') distribution, each device having a tape (32) continuous with a plurality of holes (44) separate spaced apart, a reservoir, a main length at an angle with respect to the direction longitudinal so that each distribution device covers a corresponding portion of the width of the fabric mesh; delivery of the suspension of material addition to deposit at least one device (10, 10 ') distribution; and depositing transverse bands (5) of the suspension of additive material into the fibrous web through the holes (44), wherein the length of each transverse strip is not greater than the width portion of fabric mesh for the device ( 10, 10 ') distribution.
