Abstract

A method of applying particulate matter to a cable core comprising providing first and second chambers, both of which have entrance and exit ports, the first chamber containing particulate matter and the exit port of the second chamber containing an air wipe which includes a cable core passageway in communication with the interior and exterior of the second chamber and at least one air passageway which is in communication with the cable core passageway and has an elongated longitudinal axis disposed at an acute angle to the longitudinal axis of the cable core passageway so that gas flowing through such a passageway is directed into the second chamber; passing a cable core through the first chamber and applying particulate matter to it to form a coated core; passing the coated core through the second chamber and said air wipe; and, forcing a gas through the air passageway in the air wipe onto the coated core to remove a predetermined amount of particulate matter from the coated core and transmit same into the interior of the second chamber.
