PACKAGING MACHINE FOR WRAPPING PRODUCTS IN RESPECTIVE SHEETS OF HEAT-SEAL WRAPPING MATERIAL

摘要

A packaging machine has a wrapping device for forming a tubular wrapping from a continuous web of heat-seal material, and for feeding products successively into the tubular wrapping; each product being located between two free tubular portions of the tubular wrapping, which are folded substantially onto the relative products, and are stabilized by means of at least two pairs of sealing devices fed along relative paths with independent laws of motion.
