ABSTRACT:
A packaging machine comprises a preparation station for preparing a sleeve from a stretchable plastic film wound flat around a storage reel, and a gripper device for taking hold of the sleeve and transferring it to the depositing station for enveloping the load. According to the invention, the gripper device comprises at least one set of grippers which is equipped with notched bars to create differential stretch with the formulation of a lunula. Each bar is given a translational and/or rotational movement so that the bar can be extracted and the sleeve disengaged at the end of the depositing cycle.
