Elastic roller cover for covering e.g. steel roller of paper processing machine, has pressure sensible layer arranged between adhesive layer and functional layer and/or between different positions of functional layer

摘要

The cover (4) has a pressure sensible layer (7) formed adjacent to a roller core (5). The pressure sensible layer is arranged between an adhesive layer (8) and a functional layer (9) of the cover and/or between different positions of the functional layers. The pressure sensible layer has a label part (11), which is formed from a matrix material (10) such as plastic. The label part is designed in a form of pressure sensible color pigments or liquid crystal particle, where the label part is arranged in a casing.
