ABSTRACT:
An automatic, continuous-cycle machine adapted for the wrapping of products consisting of groups of paper rolls, in which the product (P) is conveyed along a longitudinal path of travel and a wrapping sheet (15) in positioned thereon, said sheet being severed from a continuous ribbon which is unwound from a reel (21). The wrapper sheet is folded into tubular shape on the product, with partial overlapping of its edges (115-215) on the bottom of said product, and continuous sealing of said overlapped edges is then effected. Successively, the product with the tubular wrapper is rotated 90.degree. about a vertical axis, so that the portions of said wrapper which are still open are subjected to the action of final folding and sealing members.
