Abstract
A converting machine comprising a means for depositing a reactivatable adhesive onto a predetermined location of a stock material.
Claims31
A converting machine comprising a means for depositing a reactivatable adhesive onto a predetermined location of a substrate material, said reactivatable adhesive containing a reactivatable ingredient where upon exposure to radiant energy having a peak wavelength of from about 400 nm to about 100,000 nm the adhesive reactivates.
7 The converting machine of claim 1 wherein the adhesive is applied by roll coating, slot-coating, swirl spraying, ink jet printing, extrusion, atomized spraying, gravure, fiberization, flexographic printing and/or screen printing.
A side seam sealing apparatus comprising means of applying a reactivatable adhesive to a side seam flap and to predetermined other locations of a carton blank or other substrate.
A machine comprising means for forming a flat, folded packaging blank having at predetermined locations a reactivatable adhesive.
23 The machine of claim 22 wherein the reactivatable adhesive comprises a near infrared absorbing ingredient.
A method of applying a reactivatable adhesive onto a substrate surface said method comprising applying a reactivatable adhesive onto the surface of a substrate by roll coating, slot-coating, swirl spraying, ink jet printing, extrusion, atomized spraying, fiberization, gravure, flexographic printing and/or screen printing
