In the closed position, the ceiling is inclined towards the yarn path and pressure-loaded. It is raised to an open position by the pressure of the material collecting in the chamber to be set by heating. A scraper with a grooved edge cooperates with the lower feed roller and acts on the fibres leaving the rollers.</p> |
