ABSTRACT:
An apparatus for manufacturing paper board includes a hybrid papermakers fabric which facilitates both the formation of an aqueous paper board web and the dewatering of the formed web through at least one press nip. The papermakers fabric includes a woven, single-layer base fabric having a seam with a layer of fibrous batt material needled to at least one side.
Each end of the base fabric has vertically oriented loops formed from the machine direction yarns of the base fabric. The base fabric seam is defined by intermeshing the respective end loops together and inserting a joining wire or pintle through the intermeshed loops. The caliper of the body of the single-layer base fabric is inherently slightly less than the caliper of the seam. In order to reduce the effect of the seam area on the paper board manufacturing process, the end loops of the base fabric may be elongated and may contain stuffer yarns.
