ABSTRACT:
Flexible ducting apparatus includes a packaging station and compression station, a support trough for supporting the ducting in the packaging station and compression station, and an actuating post which is arranged to engage a leading end of a length of flexible ducting to be packed and pull the length of ducting in a first direction through the packaging station into the compression station. The apparatus includes a control device to cause movement of a stop member into an operative position in the packaging station downstream of a trailing end of the length of ducting, the control device then being operative to cause the actuating post to execute a second stroke in the opposite direction to the first stroke so that the trailing end of the length of ducting is compressed against the stop member in the packaging station whereby packaging can be placed about the compressed length of ducting in the packaging station. The apparatus is preferably associated with a duct forming apparatus so that the first stroke of the control device causes insulation and a jacket to be applied about a core of the ducting.
