Abstract
Floor panel of the type substantially consisting of a substrate and a top layer provided-thereon based on synthetic material. The top layer includes a printed decor and one or more material sheets provided with synthetic material. The floor panel also includes a balancing layer at the underside of the substrate, the balancing layer containing a synthetic material layer which is free from material sheets. Methods used to make the panels are disclosed.

29. Method for manufacturing panels, wherein the panels comprise at least a substrate having an underside, a top layer provided-thereon that is based on synthetic material and a balancing layer that is based on synthetic material provided at the underside of the substrate, comprises the steps:
-
providing one or more material sheets with synthetic material; making the top layer by bringing at least said material sheets and the substrate in a press device, wherein the material sheets, by a press treatment performed by said press device, are bonded to the upper side of said substrate; forming a balancing layer at the underside of said substrate, wherein, for realizing said balancing layer, prior to said press treatment, a synthetic material layer is formed at the underside of said substrate, and subjecting this synthetic material layer also to said press treatment and wherein the finally obtained balancing layer substantially consists of said synthetic material layer and is free from material sheets. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. Method for treating material sheets which are usable for manufacturing laminate panels, comprising:
starting with an absorptive material sheet having two flat sides, restricting the absorptiveness of the material sheet and then providing synthetic material on one or both flat sides of said material sheet.
-
38. Method for manufacturing laminate panels having at least a substrate and a top layer thereon, comprising the steps:
-
providing a synthetic material-containing layer on the substrate; providing on said synthetic material-containing layer an absorptive material sheet displaying a printed decor; performing, in a press device, a press treatment at least on the substrate, the synthetic material-containing layer and the absorptive material sheet such, that these are bonded to each other; wherein, above the printed decor, one or more transparent or translucent layers are provided.
-
- 39. Floor panel comprising a substrate having an underside and a top layer with a printed decor thereon, wherein at the underside of said substrate, a backing layer is provided, said backing layer comprising polyurethane.
