Benefits of technology

The invention is a protective cover for the seam loops in a paper machine's press felt. The cover is made of a solid film or plastic material that is attached to the fabric of the paper machine. The cover has a hinge that allows it to fall into position and protect the seam loops. The cover can be made from needled batt fibers or reinforced with adhesive resin. The technical effect of this invention is to provide a protective cover for the seam loops, which prevents wear and abrasion while running on the paper machine.

Problems solved by technology

In current PMC press felt seams, the seam loops are not protected from wear and abrasion on the roll side of the fabric.
