摘要

The method for splicing together first (10) and second (20) webs of pre-creased laminated packaging material for manufacturing sealed packages of pourable food products in a form, fill and seal type packaging machine, includes the steps of holding an end portion (18) of a first web (10), with its inner surface (14) oriented in a predetermined direction. An end portion (28) of a second web (20) is cut to form an undercut surface (29). The undercut surface (29) of the second web (20) is superimposed onto the end portion (18) of the first web (10), with the outer surface (27) of the second web (20) in contact with the inner surface (14) of the first web (10). The undercut surface (29) of the second web (20) is then bonded to the end portion (18) of said first web (10). At the splice (30), the inner surface (14) of the first web (10) and the inner surface (24) of the second web (20) together define an integral, continuous inner surface (14,24).
