Lacing utilizes a design with
teeth that are formed so that
when they are driven parallel to
the length of the belt, the vital
longitudinal carcass fibers are not severed.
The compression fit of the connecting bar provides a
strong, vise-like hold on the belt and distributes belt tension
evenly across the entire belt width. The one-piece fastener
strip also ensures that there are no loose pieces to work
themselves out of the belt and into the conveyed product.
The flat splice obtained with a continuous strip of lacing
also helps with hinge pin insertion.
