- the applied vacuum therefore provides for many fine products to a larger effective diameter of the compression bottle. This will degas the gas reinforced by the compression bottle and increases the effectiveness.
- the suction device can be ventilated with atmosphere or overpressure. As a result, a breakage of the bulk material cake of this first product type is effected under the action of the oscillations of the vibrator. New product then passes to the filter device and is effectively compacted.

- Figure 8 shows the enlarged detail "D" of Figure 7, the flow of the extracted air and the individual
- a seal 41 is provided.
- the extracted air is transported along the flow arrow 15 to the associated vacuum port.
- the extracted air initially flows through the air channel 28.
- the air channel 28 is delimited by the groove 40 in the connecting piece 23 (see FIG. 5) and by the tube device 9.
- Fig. 13 shows a variant of the connecting piece 23 of the
- the first connection part 23a remains on the packaging machine, while the second connection part 23b is removed together with the compression bottle 2. This allows the vacuum hoses to the vacuum ports 30 etc.
