Abstract
A method of wrapping elongated articles in groups provides for feeding a first and a second pocket continuously along two respective paths having a common portion, along which the first pocket penetrates the second pocket to transfer a group from the first to the second pocket together with a sheet of wrapping material, which is folded into a U inside the second pocket and has two parallel, opposite flaps gripped between first and second lateral walls; and for compressing the group between a first and a second bottom wall and, at the same time, extracting the first lateral walls from the second pocket.
