Definitions

  • the field of the invention relates to process belts and more specifically, to process belts used in manufacturing processes, e.g., the manufacture of pressed board or other paper products.
  • process belts are used in the preparation of pulp or materials in sheet or non-woven fabric, such as paper or board, in the Paper or Board Making Industry.
  • Such process belts are typically woven wire fabric formed into continuous or endless belts by brazing or welding.
  • end sections of such process belts are generally brazed or welded together to form a brazed or welded seam between the end sections of the process belt, thereby introducing a local stiffness at the seam.
  • brazing or welding typically degrades the strength and malleability of the wires adjacent the brazed or welded seam due to elevated temperatures. The degradation can result in premature failure of such process belts at or near the brazed or welded seam, which generally requires the process belt to be removed, repaired and reinstalled on the paper process machine or to be replaced with a new process belt.
  • FIG. 1 is an illustrative view of a process belt having a seam connecting a first end of the process belt to a second end of the process belt in accordance with principles of the invention
  • FIG. 2 is an enlarged illustrative view of the process belt shown in FIG. 1 , which shows the seam in greater detail;
  • FIG. 3 is an exaggerated side view of the seam shown in FIG. 2 ;
  • FIG. 4 is an illustrative view of the seam shown in FIG. 2 ;

  • the looped segments 26 , 34 may be distinguished from one another with markings, such as being painted different colors, for example.
  • the distinguishing markings can help ensure that a sufficient number of looped segments 26 and 34 are attached to respective end portions 14 , 16 of the belt 10 .
  • holes may need to be formed in the existing belt 10 .
  • Such holes which may be formed with a drill, an awl, a plasma arc cutter or other tool capable of forming a hole in the belt 10 , can allow ends 28 , 30 or ends 34 , 36 of the respective looped segment 26 , 34 to be woven into the belt 10 , as described above, about the horizontally extending filaments 22 .

  • Combinations of solid and braided or twisted filaments can also be used for the filaments 20 , 22 , 24 .
  • Each filament 20 , 22 and 24 can be coated, for example, to reduce corrosion and/or abrasion, through a coating process.
  • 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. Alternatively, a batch dipping can be used.

  • the looped sections 32 and 40 can be aligned with one another such that the at least one elongated resilient coupling filament 24 can be received through the openings 33 , 41 ( FIG. 3 ).
