ABSTRACT:
A method and a die tool is disclosed for forming longitudinally and laterally extending tile impressions in a strip of material in which the die tool comprises first and second cooperating parts formed as a unitary structure and each including a first section whose length is equivalent to the length of at least one tile main surface area plus the length of the stepped portion of the tile to be impressed, a single stepped portion and a second section having a complementary surface area generally parallel to the surface area of the first section. The surface areas of the first and second sections each have longitudinally extending ornamentations thereon as does the stepped portion, whereby a tile pattern can be impressed on a strip of material when the material is sandwiched between the first and second parts of the die tool.
