Abstract
A method of making a papermaker's felt which includes the steps of forming a pin seam fabric having interdigitated loops at the ends of the fabric joined by a pin. A batt of fibrous material is needled into at least one face of the fabric and across the pin seam joint. When the felt is to be installed on the papermaking machine, the pin is removed and the felt is bent back on itself at the joint to bring the portions of the batt adjacent the joint into contiguous or contacting relation and cause the loops to separate. The batt is then cut along a line extending through the separated loops to provide a flat or opened felt which can then be installed on the papermaking machine. After installation, the loops are interdigitated and the pin is reinserted through the loops to provide the endless felt construction.
