Abstract: The present invention relates to a system and method for printing an extruded sheet in which ink is applied over the extruded sheet. The extruded sheet is at an elevated temperature. The ink cures immediately upon contact with the extruded sheet having an elevated temperature. In one embodiment, at least one print roller applies a background color to the sheet and a plurality of print rollers apply one or more additional colors for forming a pattern or image on the sheet. For example, the pattern or image can have a wood grain appearance. The extruded sheet can be sized for use as a vinyl siding product.

Abstract: The present invention relates to an apparatus for continuous vacuum forming of a thermoplastic material between a pair of rotating flexible belts in which one belt includes a plurality of teeth, which are received in a plurality of indentations of the other belt. Each of the belts includes a mold, which forms a channel when the belts are adjacent to one another. A vacuum is applied to at least one of the flexible belts for drawing material received in the channel and alignment of the belts. Preferably, a vacuum can be applied to both of the belts for improved alignment. Each belt can include a plurality of apertures, which are in fluid flow communication with a plurality of perforations of a flat support belt positioned over a vacuum manifold.

Abstract: An apparatus for continuous vacuum forming a material having a flexible patterned belt continuously rotatable with a flat support belt over a vacuum manifold. The flexible patterned belt includes apertures therein and the support belt includes perforations therein for drawing air therethrough. The material is drawn onto the flexible patterned belt for vacuum forming the material.
