Automatic capping equipment, provided with a sterilizing device

摘要

An automatic capping equipment comprises at least a rotary screwing head (10) able to screw a cap (19) onto the mouth of a container (9) fed below said screwing head (10). The screwing head (10) operates in a sterile area (23) of the equipment (1) and is supported by a related sliding support shaft (12) destined to be animated with an alternating motion, whereto are associated heating means. the heating means (25) are positioned in correspondence with an operating part (12a) of each support shaft (12) proximate to said sterile area (23) and are able to perform a heating action that is localised to said operating part (12a) of the shaft (12) to maintain it at such a temperature as to guarantee its sterile condition and in such a way that the remaining part of each shaft (12) is not substantially heated by the heating means (25).
