What is Pinch Rolling and Nip Rolling?

Evans Machinery 0257 Pinch Roller

In the laminate business, pinch rolling (often called nip rolling) is a process where powered rolls are used to press together multiple sheets of material.  The pressure created from running the material through the rollers helps bond the sheets together, creating a tight bond between the material and the glue, cement, or other forms of adhesion.

Similar to a bubble in a sticker, bubbling may occur during the laminating process. Pinch rollers and nip rollers can be used to eliminate bubbling and other blemishes. Due to the importance of uniform adhesion and flawless aesthetics, pinch rollers play an integral role in laminate countertop and flat panel production.  

Multiple adhesion methods can be used in conjunction with a pinch roller. The popular Evans Midwest (Formerly Evans Machinery Inc.) Pinch Rollers can be used with both contact adhesives or fast bond PVA’s, which makes them versatile machines and ideal for a variety of applications.
