edge roll

A stronger edge is less likely to dull from fracture or from having the edge roll out of shape.

Roll-testing: A roll-testing facility was designed and built in our pilot plant to evaluate the quality of paper rolls, in particular the edge rolls.

Roll quality and tension control are IAC's expertise facilitating multiple in line slits and straight edge roll quality.

The leaves of this species are able to further aid digestion by growing such that the leaf edge rolls toward the center, bringing additional glands into contact with the prey.

This later usage with the P-Type mask caused wear & tear problems to the helmet edge roll due to the protruding P-type mask fittings (as illustrated above) abrasing the helmet leather lining & rubber edge trim.

Check the dimensions of the outer edge of the edge roll on the leather, and compare with the recess, as an equal amount of edge roll should be trimmed off each side - this keeps the leather looking symmetrical.
