Abstract
A bag-making packaging machine has a cylindrical part and a forming collar. The forming collar guides a sheet-shaped packaging material so that the packaging material wraps around the cylindrical part. The forming collar has a folded-back portion for changing a direction in which the packaging material advances to an approximately perpendicular direction. A cutout through which the thick-layered portion of the packaging material passes is formed in the folded-back portion. This reduces the amount of friction applied to the thick-layered portion when the packaging material passes by the folded-back portion of the forming collar.
