摘要 |
<p>A process for reducing rollups in gypsum board panels when the panels 15 are laminated with a laminate 30, is provided. A laminator 28 is provided, as is at least one gypsum board panel, each panel having a face paper layer 12 and a backing paper layer 14. Each paper layer has a coefficient of friction, and at least one of the face paper layer and the backing paper layer is treated with an agent for reducing the coefficient of friction and/or water absorbency. Next, a supply of laminate is provided and installed in the laminator. Then, at least one panel of the gypsum board is fed through the laminator, so that a layer of the laminate 30 is applied thereon. <IMAGE></p> |
