Claim:
Equipment for superimposing layers of products to be packaged comprising a first elongated feed surface for receiving products to be packaged, a first product feed device for moving said products along said first feed surface, first and second preparation surfaces disposed downstream from said first feed surface in vertically spaced apart relation for receiving said products from said first feed surface, second and third feeding means for moving said products along said first and second preparation surfaces, said preparation surfaces each being pivoted about axes at a downstream end of each preparation surface, a device for simultaneously controlling pivotal movement of said preparation surfaces about said axes to alternately bring a leading edge of each preparation surface into alignment with a downstream end of said first feed surface to enable movement of said packages from said first feed surface to said first and second preparation surfaces, and a movable lifting plate mounted for vertical movement downstream of said first and second preparation surfaces for receiving said products from said preparation surfaces simultaneously in stacked relation on said movable plate.
