SPINE NOTCHING (MEKANOTCH JR)SPINE NOTCHING (MEKANOTCH JR)
MEKANOTCH JR.Spine milling may be sufficient when processing book blocks with lightly sized or pulpy paper. However, when glossy, coated, or heavily calendared paper is encountered, its inability to expose fibers makes it inadequate. Traditional roughening techniques help to expose fibers to some degree, but in many instances they can be detrimental by destroying the fiber bonds at the paper edge. The MEKANOTCH™-Jr. was specifically designed to complement and enhance adhesive binding technology.
