Abstract:
Process for continuously manufacturing and filling multiple cavity bags, comprising the steps of:forming a wrapping into a tubular sleeve shape from at least one sheet of plastic material, feeding the formed plastic sleeve along a forming column, sealing end edges of said wrapping along a first longitudinal seal to form a sleeve, feeding the sleeve along two cores, sealing a part of the sleeve by sealing together mid portions of the wrapping which are spaced from said end edges while the sleeve is fed along the two cores, sealing a bottom part of the sleeve to form a partially sealed bag with two separate cavities therein, filling each of the cavities formed in the partially sealed bag through filling mouths for the cavities, closing the filling mouths to form a closed bag, cutting off the closed bag from the previous bag, and removing the closed bag.
