Abstract
A driving system in a packaging appratus is controlled by detecting when an object to be packaged reaches a predetermined position of a supplying device, driving a film supplying device to withdraw a packaging film in the form of a strip for a predetermined time and/or a predetermined length after detecting the object to be packaged at the predetermined position, and driving a cutting device to cut a predetermined position of the packaging film, formed cylindrically about the object, after detecting the object to be packaged at the predetermined position. A detecting device is provided on or adjacent to the supplying device for detecting when the object to be packaged reaches the predetermined position of the supplying device. A first driving device drives the supplying device at a constant speed. A second driving device drives the film supplying device, and a third driving device drives the cutting device. A control controls the second and third driving devices in a manner such that after the detecting device detects the object to be packaged, the second and third driving devices are driven for a predetermined time and/or a predetermined amount.
