摘要: comprises the use of pressure exerted between a rigid metallic roller, endowed with hollow holes (the desired pattern to be imprinted), and roller flexible material. Due its constitution, nonmetallic pressures areas paper - or stack sheets paper- into roller. A smooth sheet is glued over compressed against layer thus formed, while last one still has inside In consequence, only adheres that are outside imprisoning air introduced in said external applied on it. The result an embossed multilayer absorbent product bubbles presents same imprinted metal
