<p>A device turns over material sheeting whilst it is calendered and displaces it along the rollers. The roller carrying the sheeting has a blade which moves along its surface, and a parallel roller behind this blade turns over the sheeting; this roller can be offset to the blade, the blade can be moved independently. Process is suitable for laboratory use, produces uniform mix, standardises processing and eliminates manual operation e.g. in working with hazardous explosives.</p> |
