Embodiment Construction
[0025] figure 1 Shows a schematic longitudinal section through a continuous open diverter 1 equipped with a channel 10 of rectangular section for pneumatically conveying the fabric T and equipped with an impingement grid 12 facing the opening of the channel .
[0026] A system 14 for injecting air into the channel is located approximately in the middle of the channel 10 and generally above and below the fabric. The gas flow is produced by means of per se known type not shown.
[0027] The system 14 - in figure 2 shown in enlarged and more detailed manner in -comprising two directional valves 16, 18 each having two passages 16a, 16b and 18a, 18b, the passages 16a, 16b and 18a, 18b are suitably oriented to direct airflow into the channel in one direction or the other.
[0028] According to the invention, each valve also comprises an adjustable flap 17, 19 adapted to completely or partially close the inlets to the passages 16a, 16b and 18a, 18b.
[0029] Thus, the valves 16...
