Abstract: A paper web having a longitudinally extending zone coat of adhesive is continuously wound around the cylindrical surface of a rotating drum for a selected number of wraps to form a multi-layer cylindrical master stack. Web tension is controlled during winding to cause each succeeding wrap to be placed in relatively greater tension, so that when the completed cylindrical stack is cut transversely and unwrapped from the drum, equalization of the tensile stresses in the web wraps results in a flat master stack of rectangular sheets of equal length. The stack is further processed by cutting along transverse and longitudinal cut lines to form individual pads of adhesive-backed notes. Tension control may be based directly on the increase in drum radius resulting from the buildup of web wraps or by maintenance of print pattern register between continuous equally spaced print patterns in overlying wraps.

Abstract: A reinforced film of a laminate construction is thermally adhered to an edge of a web of paper stock in preparation for forming a reinforced edge of a file folder. The film has two layers, each having different characteristics, where the bottom layer becomes thermally active as an adhesive at a temperature substantially lower than the activation temperature of the other layer. The film is applied by directly heating the top layer to a temperature which in turn heats the bottom layer to a temperature where it acts as an adhesive. The layers can include a printed surface intermediate the film which is visible through the top layer or the layers can include an appropriate pigment to color code the edge of the folder. The apparatus can be added to existing file folder machines to apply the film without the need for sophisticated controls to tie the apparatus to the operation of the file folder machine.
