Abstract
A method and apparatus for forming the bottom of a carton on a form, fill and seal packaging machine such as the TETRA REX® packaging machine includes a sealing station for a bottom forming station that includes a pair of rotating spindles. Each spindle has a pre-folding member and a final folding member for infolding the bottom panels of the carton. The sealing station also includes a guide plate for guiding the final folded bottom panels of the carton to a sealing plate for permanent sealing. The bottom formed carton provides a tight seal, particularly for an over-folded carton, for use in packaging a product.
