Abstract: A method for producing elasticized composite side panels and non-elasticized side panels, comprising: feeding a continuous web of a first non-extensible material having longitudinal side edges along a first direction parallel to a longitudinal axis of said web, forming in said web, in a position within said longitudinal edges, and at a pitch, a plurality of oblong openings having a major axis substantially parallel to the longitudinal axis of said web, each opening having a maximum transverse dimension with a first length, a maximum longitudinal dimension with a second length, and two longitudinal end zones, forming a plurality of rectangular elements of elastic material having in a relaxed condition two minor sides with a first dimension greater than said first length and two major sides with a second dimension at least equal to said second length of said oblong openings, said elements of elastic material being elastically extensible at least along the first dimension, transferring each of said rectangular elements of elastic material in a relaxed condition onto said continuous web at each oblong opening and in a substantially centered position with respect thereto, welding each rectangular element to said continuous web along at least the respective longitudinal edges superimposed on the longitudinal edges of each oblong opening, so as to form a continuous composite web, making transverse cuts at predetermined intervals on said continuous composite web so as to remove transverse portions from said continuous composite web comprising the longitudinal end zones of each oblong opening and the corresponding minor sides of each respective rectangular element of elastic material, to form alternately individual elasticized composite panels comprising said elastic material and individual non-elasticized panels not comprising said elastic material.
