A process for manufacturing a sheet having a chip-like design composed of a plurality of chips densely aligned in a plane without overlapping and a solidified binder uniformly filling the interstices among the chips and firmly and integrally bonding the chips to one another in sheet form. The sheet is useful as a floor material, wall material, and the like.

Process for producing a sheet having chip design

A method and apparatus for producing synthetic resin sheets having geometric decorative patterns extending through the thickness of the sheet as a substantially identical pattern image corresponding to the image portions of the exposed surfaces thereof, wherein differently colored resin particles are selectively introduced into individual pattern spaces which are confined by enclosing members on a support to provide a regular pattern of differently colored resin particle masses over the surface of the support in a regular pattern, the differently colored resin particle masses are then converted into a pre-formed sheet on the support, the regular color pattern still being retained, and the resulting assembly then being heated at a temperature sufficient to cause fusion or sintering together of the masses of differently colored resin particles comprising the sheet, wherein the original differently colored resin particle masses exist as a repeating pattern of differently colored areas which extend through the thickness of the sheet.
