Abstract

Method for manufacturing straws (50) comprising: providing a web or discrete sheet (1a, 1b) made of paper material which extends between a first and a second end portion (2, 3); providing a winding body (11) extending along an axis (A) and winding it around said web or discrete sheet (1a, 1b) to define a cylindrical body (5) in which the end portions (2, 3) face each other to define a mutual overlapping portion (4); constraining the end portions (2, 3) to define a straw (50) extending between a first and a second circular free edge (51, 52), said mutual overlapping portion (4) extending between the first and second free edge (51, 52) of the straw (50) along a straight direction.
