How Alligator
®
Lacing Works
Hammer applied Alligator
®
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.
