A method and an apparatus for improving the operating efficiency of a wrapping machine (10), by providing the wrapping machine (10) with two or more wrapping carriages (30a, 30b) or similar devices for two or more plastic film band rolls (31a, 31b), each of which can be taken into use in turn at any time. To permit a roll change, the wrapping machine is provided with a switch-over gripper (50) for gripping the end (33b) of the plastic film band (32b) coming from a full plastic film band roll (31b) and for pulling it onto a seaming gripper (40) before the wrapping of the next object (10) to be wrapped is started. |
