FIELD: mechanical engineering.
SUBSTANCE: tension mechanism designed for installation in a portable packaging machine contains a mechanism for controlling the direction of rotation and holding the rotation angle, a non-return mechanism, and a swing arm. The rotation direction control and rotation angle holding mechanism is connected to the non-return mechanism and the swing arm. The swing arm is equipped with a toothed structure mating with the tension wheel.
EFFECT: compact design, improved performance of the tensioning mechanism.
