Definitions

  • the field of the invention relates to broadloom fabrics and more specifically, to broadloom fabrics used in manufacturing processes, e.g., washing, forming, pressing, curing and drying of various industrial products.
  • broadloom fabrics are used in the preparation of pulp or materials in sheet or non-woven fabric for various industries, such as paper making industries, for example. Such broadloom fabrics provide strength and surface requirements needed by such industrial processes as washing, forming, pressing, curing and drying of various products. Broadloom fabrics can have widths of 120 inches or more and are typically formed with one- piece continuous fabrics.
  • Fabric is used herein to describe all materials including fabric, cloth, metal, plastic and other materials, capable of carrying pulp or industrial materials or products used in manufacturing processes, e.g., washing, forming, pressing, curing and drying of various industrial products. Fabrics can be wound around a core to form supply rolls constructed and arranged to store the fabrics until the fabrics are used in a manufacturing process.
  • broadloom fabrics are manufactured in various fixed widths, e.g., 120, 175, 250, 300 or 350 inches so that different broadloom fabrics can be used in different manufacturing processes or applications. For example, devices to perform some processes might require a 300 inch broadloom fabric, whereas devices for other processes might require a 200 inch broadloom fabric. Because broadloom fabrics have been typically formed with a one-piece fabric having a fixed width, high inventories of broadloom fabrics having various widths are required to meet expected industrial needs. These high inventories of broadloom fabrics can become obsolete should the need or requirement for those specific widths change. [0006] Additionally, broadloom fabrics have been difficult to manufacture due to widths thereof being 120 inches or more. As such, production of such broadloom fabrics is generally slow and costly.

  • the broadloom fabric 10 can have widths of 120 inches or more. In some applications, the broadloom fabric 10 can have widths of at least 300 inches, which can include five 60 inch wide fabrics similar to any one of fabrics 12, 14 or 16, for example.
  • FIG. 2 shows narrow fabric 12 in greater detail, but is representative of each fabric 12, 14 and 16 because each fabric 12, 14 and 16 includes elongated filaments 24, 26 described below with respect to fabric 12.
  • Fabric 12 can include a first plurality of elongated resilient filaments 24 oriented in a first direction. The first direction can be referred to as a machine direction and each elongated resilient filament 24 can be referred to as a warp filament, for example.
  • Fabric 12 can also include a second plurality of elongated resilient filaments 26 oriented in a second direction transverse to the first direction.
  • the second direction can be referred to as a cross machine direction which defines the width of the fabric 12 and each elongated resilient filament 26 can be referred to as a shute or weft filament, for example.
  • Narrow fabrics 12, 14 and 16 can each have a width of 10 to 120 inches, for example, but generally have a width ranging from 48-90 inches.
  • the individual filaments 24, 26 can be woven together, for example, using a weaving apparatus, or may be woven manually, to form the fabrics 12, 14 and 16.

  • the coating may be a low friction and contaminant resistant protective coating, for example, and may include brass or some other hardening (corrosion and abrasion resistant) material.
  • the low friction and contaminant resistant protective coating can be applied by conventional coating techniques, such as dipping or continuously running the filaments through a bath, such as electrode plating, for example. Alternatively, a batch dipping can be used.
  • the shute or weft filaments 26 at edge 20 of fabric 12 can be joined, e.g., through couplings 22 to the shute or weft filaments 26 at edge 18 of fabric 14.
