Equipment for superimposing layers of products to be packaged (P), comprising: a feed surface (12) associated to a first product-feed device (18); and a pair of preparation surfaces (24, 26) set on top of one another and designed to receive each a respective layer of products to be packaged (P), the preparation surfaces (24, 26) being associated each to a respective feed device (36, 38), the said feed devices (36, 38) being designed to cause synchronized advance of corresponding layers of products (P) along the preparation surfaces (24, 26). Both of the preparation surfaces (24, 26) are mobile so as to bring alternately the respective product-intake end (28, 30) into a position corresponding to the product-output end (16) of the feed surface (12).
