Abstract: A method and an apparatus for fixing an image formed by a colorant upon an image support body is described. A fluid, binder material contacts a heated transport surface. The heated surface comprises an elastomeric material which is positioned on a tubular body formed of a material having a relatively high coefficient of thermal conductivity. The transport surface advances the heated binder material to a nip formed with an adjacent pressure contact surface which is transported in moving engagement with the heated surface. The binder material at the nip temperature exhibits a viscosity which exceeds the surface energy of the elastomeric transport surface while the surface energy of the support material and the imaged surface is greater than the surface energy of the elastomer. The binder is thus transferred to the imaged surface for fixing the image thereon.

Abstract: An improved machine and method for stiffening a selected portion of a sheet-like member generally flattens that portion, next deposits on a chill plate matrix an adhesive hot melt deposit of mostly uniform thickness except for a margin of added thickness for slower hardening, and then causes the matrix with impact to press all of the adhesive, while the added thickness margin is still softer than the uniform adhesive thickness, against the flattened portion of the member, thus transferring the adhesive to that portion, the added thickness margin being exuded laterally and hence taperingly reduced to provide diminishing stiffness toward an edge merging with the member.The machine and method have particular advantage in stiffening a toe portion of a shoe upper, rendering the instep margin of the vamp or a toe piece free of irregularity, and assuring ultimate comfort for wearing in an assembled shoe.

The device includes a reservoir within which the wheel is partially submerged in molten adhesive and a doctor blade for controlling the thickness of adhesive applied to the substrate. The reservoir is so configurated that so long as the wheel is rotating, there is a continuous flow of molten adhesive from the pool beneath the wheel up to the doctor blade, along the underside of the doctor blade and back to the pool via channels in the end plates of a reservoir. To prevent the substrate from adhering to the surface of the wheel, stripper fingers extend parallel to the path of movement of the substrate and ride within annular channels or grooves in the periphery of the wheel.
