ABSTRACT:
Friction spinning apparatus comprises a fibre feed duct having a secondary suction port which is linked to a source of suction by way of a second perforated region of the perforated roller. The secondary air passage is communicated to a source of suction by way of the second perforated region having a suction opening formed in a masking sleeve therewithin. Yet a further masking sleeve radially inwardly of the first has two differently sized holes for changing the volume of air flowing through the hole and hence changing the airflow rate through the secondary air passage.
The secondary air passage can be relatively large in cross-section and the flow constriction of the secondary air path can be by way of the second perforated region of the roller which is self-cleaning and hence avoids blockage of the secondary air path.
