Abstract:
The injection heads (1) of a filling machine are mounted in alignment with the horizontal delivery unit (5), intersecting it horizontally. The delivery unit (5) connects with the fixed line (11) by means of an articulated tubular duct (12) with tight rotary joints (13) that allows it to shift in the space, keeping a horizontal orientation. The unit (5), the duct (12) and the line (11) have a constant diameter and can be internally traveled by at least a scraping pad (15) that passes through and cleans also heads (1). Injectors (7) of heads (1) discharge from the residues and clean either by gravity of by means of additional independent scrapers (37).
