ABSTRACT:
A method and device for producing tubular wrappings for products of parallelepiped shape or similar; whereby the products are fed successively, and in a substantially radial direction, to a wrapping wheel turning at substantially constant speed and having a number of mobile elements, each defining a seat for a respective product. Each product is inserted inside a respective seat together with a sheet of wrapping material, which is folded in a U and presents two opposite portions projecting outwards of the seat. One of the portions is folded down on to the product by a first folding element, and the mobile element is moved on the wheel so as to fold and hold down the other portion by means of a second folding element mounted on the wheel, and so as to move the seat into a position facing a joining device for firmly joining the two folded opposite portions of the sheet of wrapping material.
