摘要：To envelop a group (19) of products completely in a wrapper (23) of
parallelepiped appearance with two end faces (25), a wrapping material (3) is decoiled and
divided up cyclically along transverse cutting lines (T) to generate single sheets (2) each
with transverse edges (2i, 2s) of which one receives a coating of gum (16) dispensed along
a transverse line (G), parallel to the cutting line (T), by a first applicator (12); the sheet (2)
is then passed around a relative group (19) of products, its two edges (2i, 2s) joining to
form a tubular wrapper (23) with open ends (28) each consisting in a set of projecting
folds (13, 39). The wrapper (23) and its contents are transferred toward a folding unit (40)
where more gum (16') is applied to at least one of the two end folds (13, 39) by a second
applicator (18), whereupon the folds (13, 39) are flattened to close up the end faces (25).
