High speed cold adhesive curing process and apparatus therefor

Abstract

This invention is directed to a high speed cold adhesive curing process and apparatus therefor, useful in the assembly and fastening together of fibrous surfaces such as the surfaces of corrugated Kraft paper cardboard boxes. The invention is directed to a process for adhering two fibrous surfaces together by means of a liquid cold cure adhesive comprising: (a) spraying liquid cold cure adhesive on the interface surface of one of the fibrous surfaces in a thin discrete particle pattern; and (b) pressing the two fibrous surfaces together under high pressure sufficient to cause the solvent carrier in the cold cure adhesive to disperse into the interstices of the fibres of the two surfaces, thereby enabling the cold cure adhesive particles to rapidly secure the two surfaces together.
