ABSTRACT:
In a pneumatic filter rod conveying system a vent (12) is in the line (10) close to the distributor (2). This enables a relatively high pressure gradient to be established, with resultant high filter transfer rates at the distributor, without having excessively high pressures in the distributor and/or higher than necessary line transmission speeds. Also, there may be a selectable pressure switch (40) for reducing air pressure at the distributor when there are fewer than normal filters in the line, e.g., at the end of a run: this also allows avoidance of undesirably high line transmission speeds.
