摘要

A method and a manufacturing machine (10) for the production of capsules (1) for smoking articles, in particular for filters, designed to contain a liquid to be used in the cooling of smoke; wherein each capsule (1) comprises a cup-shaped body (2) and a covering element (7); the manufacturing machine (10) comprises a welding station (S5) for welding a strip (14) of plastic material to a plurality of cup-shaped bodies (2); a cutting station (S6) for cutting the strip (14) of plastic material welded to the cup-shaped bodies (2) so as to obtain the covering elements (7), wherein the cutting station (S6) is arranged downstream of the welding station (S5); and a dragging device (22) for the strip (14) of plastic material that is interposed between the welding station (S5) and the cutting station (S6) and adapted to obtain a loop (23) of plastic material which allows the two groups of semifinished capsules (1) to be independent.
