摘要: A method of applying a coating of hot melt polymeric material from a die to a substrate. Hot melt polymeric material is extruded through the die onto the peripheral surface of a rotating application roller to provide a coating layer along that peripheral surface. A substrate is conveyed past the peripheral surface of the application roller at an application interface to cause transfer of the first coating layer to the substrate and shearing and thinning of the coating layer because the substrate is conveyed faster that the peripheral speed of the application roller. The velocity of the peripheral surface and spacing between the die and the application interface along are selected to provide a time inteval of at least 0.12 second for movement of portions of the coating layer from the die to the application interface, thereby affording relaxation and molecular reorientation of the hot melt polymeric material after the extruding step to facilitate shearing of the first coating layer at the application interface without causing ribbing or breaking of the coating layer.

摘要: A binding assembly including (1) a plurality of support strips; (2) layers of pressure sensitive adhesive (which could be repositionable, removable or permanent pressure sensitive adhesive) along front surfaces of the support strips; and (3) layers of release material on a rear surface of the support strips. The support strips are adhered together to form a support strip stack with inner edges of the support strips in alignment, with the layers of pressure sensitive adhesive on the support strips adhered to the layers of release material on adjacent support strips, and with the front surfaces of the support strips uppermost in the support strip stack. The binding assembly further includes binding means along the inner edges of the support strips that affords separation of the support strips and revolving of the support strips relative to each other around axes generally parallel to their inner edges. Only tension applied through a paper sheet adhered along the full length of the layer of pressure sensitive adhesive on the uppermost one of the support strips adhered in the support strip stack can be used to separate that one support strip from an adjacent support strip adhered to the layer of release material on the front surface of that one support strip and cause revolving of that one support strip away from the support strip from which that one support strip was separated.
