Abstract
The total heating energy to be given to the folded parts of packages (i.e. box-like items) is changed within a short period of time in response to a variation of transferring speed of the box-like items. As the heater moving mechanisms are operated, each of the heater blocks is moved towards or away from the inside parts of each of the package conveying annular belts in synchronization with the transferring speed of the box-like items. The number of heated blocks abutting against the inside parts of each of the annular belts is varied in response to the transferring speed of the box-like items.
