Abstract:
1. A method of making product wraps, comprising the steps of: causing a continuous strip of wrapping material, having at least two first adhesive bands extending parallel with its longitudinal dimension, to advance along a predetermined path, the strip also having second adhesive bands extending transversely to the longitudinal dimension of the strip; cutting the strip transversely along dividing lines to obtain a plurality of leaves each having longitudinal edges coinciding with relative dividing lines, the dividing lines also separating the second adhesive bands; establishing at least one portion between the two first adhesive bands and coinciding with each transverse dividing line from which to initiate an easy tear along a direction substantially transverse to the longitudinal edges of the leaf, generating, on each easy tear portion, at least one first notch on each dividing line, extending parallel to the longitudinal dimension of the strip and intersecting the dividing line, generating a second notch, establishing at least one indentation, intersecting transversely each first notch; the second notch coinciding with the dividing line to create a projection on an opposite longitudinal edge of each leaf that projects beyond the dividing line, the projection being divided into two transverse portions by the first notch which longitudinally extends along the projection itself, the first notch being limited in length so as not to extend longitudinally beyond the respective second adhesive bands and thereby intrude in a substantially centrally located product placement zone positioned between the second adhesive bands and the first adhesive bands of each leaf; associating at least one product with the respective product placement zone of each leaf; folding each leaf around the at least one product and bringing together the two longitudinal edges to adhere the second adhesive bands and form a tubular sheath; closing the ends of the tubular sheath to adhere the first adhesive bands and obtain a wrap around the product.
