In the device according to the current patent EP 3330192 A1 for wrapping containers, including bottles, a wrapping station is provided in which the film is continuously wound in a spiral onto rows of containers moving along the displacement axis, a cutting and separating unit equipped with a bridge carriage moving in accordance with with an axis of movement parallel to the direction of movement of said containers, on which a cutting device is installed, which is moved across said axis of movement. The hot knife cutter is mounted on a moving frame that is integrally mounted with a moving carriage.

In addition, the device is additionally capable of synchronizing the translational movement of said bridge carriage with the movement of said rows of containers based on control determined by the counting sensor for said containers, as well as synchronizing the translational movement of the carriage with the conveyor belt, so that their speeds are substantially identical.

Known "Line for packaging products in a shrink film" according to patent RU 120399, containing sequentially located packaging module, a conveyor with a heat chamber installed above it and a receiving roller conveyor, while the packaging module includes:

- a vertically located rectangular frame, on which the thermal knife is installed with the ability to move along the vertical racks, as well as the table, the clamp and the upper and lower units for unwinding the film are fixed on the frame, and a stop for the thermal knife, a pusher and stops for centering the product block are installed on the table, moreover, the upper horizontal beam of the frame is formed by the upper unwinding unit connecting the upper ends of the vertical racks of the packaging module frame, while the guides of the thermal knife are made in the form of rods passing along the entire length of the vertical racks of the frame and fixed by the lower ends on the lower horizontal beam of the frame, and the upper ends on top unwinding unit.
