Adjacent first segments are joined together via a second segments comprising second material, wherein the second segments extend past the first major surface of each first adjacent segments. The articles further include an adhesive on at least one of the first or second major surfaces of the first segment. The first segments, second segments, and third material each extend continuously for at least 5 mm in the machine direction, and the first and second materials of adjacent pairs are periodically bonded together in the machine direction. A portion of some of the first segments of the first coextruded polymeric netting are engaged between some of the adjacent first segments of the second coextruded polymeric netting.

摘要： The process includes a non-crosslinked self-sealing composition which is introduced into an extrusion means, the geometric and thermodynamic characteristics of which have been specially adapted. The speed and temperature conditions of the extrusion means are adjusted so that, at an application nozzle forming the outlet die of the extrusion means, the self-sealing composition is crosslinked. The application nozzle is brought close to the internal surface of the casing previously set in relative motion with respect to the application nozzle, and an extruded and crosslinked bead that has a given width and profile is deposited directly on the internal surface of the casing.
