ABSTRACT:
The discharge device of this invention serves to receive axially compressed radially self-sustaining tubular duct in a cartridge form substantially shorter than the fully extended length of the duct and has a restraining collar on an exit end of the discharge device which effects a hoop tension on the compressed core during its passage from the exit end of the device to apply a controlled frictional drag ensuring that the core upon discharge is in a fully extended condition.
