A SEALING APPARATUS FOR SEALING WRAPPERS CONTAINING SETS OF CYLINDRICAL PRODUCTS ARRANGED IN BUNDLES

摘要

A sealing apparatus (1) for sealing wrappers (2) containing sets of cylindrical products (3)arranged in bundles comprises: a table (4) for supporting the products (3) resting on their base; a pair of continuous conveyors (5) with vertical axis, reacting against one another so as to firmly clamp the products (3) between them, feeding them forwards along the supporting table (4); a set of heat exchange means (13A; 13B) and a set of means (13C) for pressing the wrapper (2); and sprung tensioning means (10, 16, 17) for the endless belts (7). The conveyors (5) have two rollers (6), both motor-driven. They also have sprung tensioning means connected to the active branch (8), so that it is sprung in a direction (11) transversal to the plane in which it lies and can automatically configure itself in such a way that it matches the outline (12) of the products (3) opposite it.
