A method for embossing a first grating in a planar material, by means of an embossing body and a counter embossing body, having each a hard surface, the first grating to be embossed comprising alternating substantially parallel and straight ridges and recesses, whereby the top surfaces of the ridges are intended to weaken a direct angular reflection of light by diffuse omnidirectional reflection, thereby producing a visible contrast between the ridges and the recesses. The method comprises on the embossing body providing a first plurality of obtuse pyramids intended to emboss the recesses of the first grating by exerting pressure on a first side of the planar material, the first plurality of obtuse pyramids forming first intermitted lines (row1, row2) corresponding to the intended recesses, and the pyramids in each subset corresponding to one of the first intermitted lines, being separated from each other by a determined distance that creates a gap in the line in such a manner that each gap from a line of pyramids may be connected to a corresponding gap from an adjacent line of pyramids by an imaginary line perpendicular to both of the adjacent lines; and roughening portions of the hard surface of the embossing body, the portions being located between adjacent lines of pyramids and intersecting at least one of the imaginary lines that connect one gap from one line to the corresponding gap from the adjacent line. On the counter embossing body, the method comprises providing a second plurality of obtuse pyramids intended to emboss the ridges of the first grating by exerting pressure on a second side of the planar material opposite to the first side, during embossing the obtuse summits of the pyramid pressing the planar material against a roughened portion of the hard surface of the embossing body, thereby satirizing the top surfaces of the ridges on the first side.

Portable method and apparatus for folding plastic composite flooring
11485166 · 2022-11-01 · ·

A method of folding plastic composition flooring, including but not limited to LVP, LVT, SPC or WPC, to form a desired shape, such as stair noses, baseboards, quarter rounds, T-moldings, endcaps, or the like. The method includes the steps of incorporating a thermal insulation layer between the plastic composite flooring and a heat generator, applying heat until reaching a heat transmission coefficient to allow the plastic composite flooring to become malleable, removing the heat, applying pressure to the heated section of the plastic composite flooring to form into a desired shape using a positive and negative embossing die mold on the top and bottom heated section of the plastic composite flooring, and removing the embossing die-molds once the plastic composite flooring has cooled down to its initial temperature.

MARKING SYSTEMS AND METHODS FOR FIBER-BASED PRODUCTS
20230131528 · 2023-04-27 ·

A method of marking a fiber-based product includes providing a heat stamp apparatus including a heating element thermally coupled to a stamping block and a temperature sensor thermally coupled to the stamping block. The system further includes a platen bearing an embossed pattern. Marking is accomplished by heating the stamping element to a predetermined temperature via the heating element and information acquired from the temperature sensor, then bringing the embossed pattern in relation to the surface of the fiber-based product (e.g., via direct contact and compression or simply very close to the surface) to form at least one of a corresponding three-dimensional contour and charred surface region.

Clamping device

Flat foil printing press having foil web and sheet guidance
20170361641 · 2017-12-21 ·

The flat foil printing press comprises an evacuable back-pressure plate (9), with suction regions (15k) which run in the sheet running direction (X) and which are next to embossing regions (16k), in which foil webs (6k) run. The suction regions are subdivided into several suction segments (10i) which are successive in the sheet running direction, and are each connected to a vacuum source (14) by way of a vacuum feed line (12i) via a vacuum switching element (13i). With the running-out of an embossed sheet (5), firstly all suction segments (10i) covered by the sheet are evacuated, and subsequently the suction segments which are no longer covered by the sheet are successively disconnected from the vacuum source. This results in an error-free separation of foil webs and sheets, for a greater picture quality and machine output.
