Abstract
A packaging machine for filling a fluid food or like contents into containers fed to a conveyor and each coated with a thermoplastic synthetic resin over the outer surface thereof and thereafter closing the containers while the containers are being transported by the conveyor. The container transport path has at an intermediate portion thereof a station where hot air is applied to each container, for example, for heat sealing. The conveyor is provided with rails for guiding the container by supporting the bottom thereof. If the rails are heated with the hot air, the resin is likely to adhere to the rails on melting. The rails are provided with a cooling water channel for cooling the rails to eliminate this drawback.
