Composite web
A composite web including a first continuous web having a first face and a second face; the first web includes a molded portion having at least one protrusion, at least partly delimited by a base portion, on the first face; the composite web includes a segment of a second continuous web joined to the second face of the first web at least at the base portion.
1 . A method for production of a composite web for sanitary articles, comprising the following steps:
feeding a first continuous web,
molding the first continuous web to obtain at least one protrusion, the protrusion being delimited at least partly by a base portion,
feeding a second continuous web,
cutting the second continuous web into a plurality of individual segments,
spacing apart the segments
joining the spaced apart segments to the first continuous web at least at the base portion to delimit at least one cavity between each of the segments and the first continuous web.
2 . The production method according to claim 1 , wherein the step of joining the segments to the first continuous web comprises a step of welding each of the segments to the first continuous web at least at the base portion.
3 . The production method according to claim 1 , wherein the step of joining the segments to the first continuous web comprises a step of holding each of the segments on the first continuous web.
4 . The production method according to claim 1 , wherein the step of joining the segments to the first continuous web comprises a step of disposing a layer of adhesive between each of the segments and the first continuous web.
5 . The production method according to claim 1 , wherein the step of molding the first continuous web comprises a step of molding the first continuous web along a full length thereof, the step of joining the segments to the first continuous web defining a molded portion at least at each of the segments.
6 . The production method according to claim 5 , wherein the step of joining the segments to the first continuous web comprises a step of joining a discrete succession of the spaced apart segments to the first web, each of the segments of the discrete succession defining a corresponding molded portion in the composite web.
