Abstract:
Apparatus and method of increasing adhesion of thermal binder strips to coated papers by conditioning an edge of the sheet by splitting the edge which results in an expansion of the edge followed by compressing the edge so as to reduce or eliminate the expansion. In the case of a stack of sheets, the edge of the stack is conditioned by piercing the edge of the stack and in the case of an individual sheet, the conditioning is carried out by splitting at least a portion of the edge of the sheet.
