Abstract
A packaging machine of the type having a mechanism for tubulating a belt-like film and a conveyor for transferring products into the tubular film is typically equipped with a pair of sealing bars which produce transverse seals between the products being packaged. The present invention relates to a mechanism which is able to control the length and speed of the stroke of the sealing bars and the speed of the film dependent on the length of the product being packaged which assures more uniform heating of the seals resulting overall in more uniform transverse seals.
