Abstract
An apparatus for wrapping products with plastic film includes: a ring-shaped element supporting a carriage; a drive mechanism for moving the ring-shaped element relative to the group of products; and, a motor for driving the carriage. The carriage mounts a roll of film and a pre-stretching unit that includes a pair of rollers and a transmission and control roller that swings towards and away from the products and is designed to start or stop film feed according to its position relative to the products. The drive mechanism for the pre-stretching unit includes a kinematic chain including the motor and a drive take-off track. An engage/release unit is connected to and controlled by the transmission roller and designed to transmit drive from the take-off track to the pre-stretching rollers according to the position of the transmission roller.
