Abstract
A papermakers fabric is made with a woven base fabric having two ends. The base fabric includes a single layer of machine direction yarns having a system of cross machine direction yarns interwoven in a repeat pattern. At each end of the base fabric, the machine direction yarns are formed into a series of loops with an angular orientation so that the base fabric ends can be joined by intermeshing the respective end series of loops and inserting a pintle through the intermeshed loops. The angular orientation of the loops on one end of the base fabric are formed in the opposite direction from the angular orientation of the loops of the other end of the fabric when said respective end loops are intermeshed. The base fabric is heat set with the base fabric ends joined with a pintle such that both series of end loops take on a substantially vertical orientation.
