Abstract
A capping machine (1) of carousel design comprises a centre shaft (2) turning on a fixed base frame (3) about a vertical axis of rotation (Y), a set of capping units (4) encircling and revolving as one with the shaft (2) about the axis of rotation (Y), and a cylindrical cam (5) interposed between the shaft (2) and the capping units (4), by which the single units (4) are caused to move toward and away from the fixed base frame (3). During operation, the cam (5) is held in at least one predetermined fixed position relative to the base frame (3) by a single supporting element (6) anchored to the base frame (3), concealed internally of the rotating shaft (2) and connected to the cam (5), which represents a departure from the conventional method of supporting the cam on two or more columns located externally of the carousel structure and exposed to view.
