Abstract
A method of bonding a substantially planar sheet material to a corrugated sheet material using an automated process the method characterized by the steps of a) applying adhesive in discrete amounts to the contact points of the corrugated sheet material, and b) holding the sheet materials together until a bond is formed between them.
Claims15
A method of bonding a substantially planar sheet material to a corrugated sheet material using an automated process comprising the steps of:
- a) applying adhesive in discrete amounts to contact points on the corrugated sheet material with a roller having a contoured outer surface in the form of corrugations, and
- b) holding the sheet materials together until a bond is formed between them.
A machine for making single face corrugated board by bonding a corrugated sheet material having one or more crests onto a substantially planar sheet, the machine including a roller configured to apply adhesive in discrete amounts to the crest of the corrugated sheet material, and a pressing mechanism configured to hold the planar sheet against the crest until a bond is formed between them, wherein the roller has a contoured outer surface in the form of corrugations.
