Appl. No.:

10/922149

Inventors:

Eugene Z. Fekete - Dunwoody GA, US
Edwin R. Perry - Vancouver WA, US
Robert P. Burke - Berkeley Lake GA, US

Assignee:

AstenJohnson, Inc. - Kanata, Ontario

International Classification:

D21F 7/10

US Classification:

1623582, 162900, 162904, 139283 AA, 442240, 442247, 428 58

Abstract:

A multilayer papermaker's press felt fabric comprising in combination a woven first fabric layer, typically a double layer fabric, has a cross machine direction pin seam. A second fabric layer is located on the paper side face of the first fabric layer, and a layer of needled batt is applied to the paper side face of the second layer binding the layers together. A flap comprising a short length of the second fabric layer with attached batt overlays the pin seam area in the first layer. The second layer comprises a plurality of relatively narrow strips, which are located with a lateral edge at a first cant angle of from more than 1 to less than 20 to the machine direction. A third layer, similar to the second layer, can be included on the machine side of the first layer; the strip widths, the cant angles, and the direction of the cant angle relative to the machine direction for each of the two strips need not be the same. The fabric is assembled using a spiral winding technique.
