Abstract:
A seam construction for a woven dryer fabric for a paper machine comprising at each end of the fabric, a helical spiral or an array of loops which can be interdigitated to enable a pintle wire to be passed through the interdigitated loops, and are stitched or woven into the fabric by loop engaging yarns extending in the machine direction of the fabric in which a neutral plane of the fabric is displaced from a central plane of the fabric towards a paper contacting side of the fabric, wherein at each end of said fabric adjacent the respective spiral or loops, at least one pair of cross-machine direction yarns is disposed, the yarns of said pair being substantially equal in diameter which will enable the seam spirals or loops to lie in the geometric plane of the fabric rather than in the neutral plane.
