LIGHTWEIGHT COMPOSITE ELEMENT, METHOD FOR THE PRODUCTION AND USE THEREOF

摘要

The lightweight composite element consists of at least two nap films or nap sheets (2;3) made of plastic, i.e. plastic films or sheets on which a plurality of naps are formed on at least one side thereof. The nap films or sheets (2;3) are directed towards each other and are firmly welded or glued together. The method for the production thereof requires at least two nap films or sheets made of plastic which are displaced mechanically from a roll (9,10) or from stacks and which pass by an automatic machine which welds them together or glues them together as they go past, whereby a virtually endless sheet of lightweight composite elements is produced and can be subsequently separated into sections of various lengths.
