<p>A method and apparatus for preconditioning laminated paper for recycling includes a tank 20 in which shredded corrugate C is immersed and shuffled in a solvent fluid S capable of attacking and weakening the adhesive bonding the core ply of the corrugate from the liner plies thereof. The corrugate is advanced from its entry point 24 into the tank to an exit point 26 therefrom at a timed rate to limit its absorption of the solvent fluid S prior to its transfer to delaminating apparatus. When the adhesive is starch, the solvent may be water, and a wetting agent may be added. <IMAGE></p> |
