FIELD: equipment for closing of sleeve-shaped or bag-shaped packaging enclosure filled with product such as sausage farce.
SUBSTANCE: apparatus has means for narrowing of packaging enclosure and forming of enclosure upper portion free from filler product, closing means for setting and closing of at least one locking clamp around upper portion of enclosure, and drive for narrowing means and closing means. Drive has non-uniform transmitting means which converts uniform drive motion into periodic non-uniform drive motion. Transmission ratio of transmitting means is selected so that upon setting of closing means output speed is reduced as compared to output speed developed during narrowing and replacement processes. Transmitting means is toothed belt transmission or chain transmission with at least one elliptical toothed gear or at least one toothed gear arranged with eccentricity. Apparatus of such construction allows drive to be coordinated with desired procedure.
EFFECT: increased efficiency and reduced power consumption.
