Abstract
A pintle unit and method of closing a seam in a papermakers felt which provides a tight closure along the full length of the seam. The seam is closed with a pintle unit made up of a plurality of pintle elements which are tapered and pulled into the seam to interact in a wedging fashion. The pintle elements are tapered for a length at least as long as the width of the seam so that when wedged in the seam a pintle unit of substantially uniform size across the full width of the felt is provided.
