Abstract
A metering roller is for filling a vessel with a portion of a powder product to be metered. The metering roller includes a roller jacket, a filter element, a filter strip, a seal and a clamping core. The roller jacket defines at least one metering opening completely penetrating the roller jacket from its outer side to its inner side, the metering opening being delimited on the inside via a filter element. The filter element is pressed by the clamping core via the filter strip against the inner side of the roller jacket. The seal is arranged between the filter element and the filter strip, the metering opening being exposed to a negative pressure through the filter element via at least one pressure channel in the filter strip. The seal seals a connection of the pressure channel to the metering opening. The seal is an elastomer cured onto the filter strip.
