Zusammenfassung:PURPOSE: To make exchange of stretch film rolls possible without letting a machine stop. CONSTITUTION: This machine comprises a mechanism wherein film roll support parts 51a and 51b support two film rolls in adjacency and sensors 58a and 58b for detecting the size of diameter of each of the rolls. A heat sealer 56 for splicing the front end of a film to be used thereafter out of two films unwound from the two film rolls to a film used theretofore and a cutter 55 for cutting a remaining part of the film used theretofore are provided at positions between the support parts and tensile force-giving mechanisms 52a and 52b that give tensile force to the films.
