A machine for manufacturing disposable cups, including a side element, obtained from a blank of sheet material folded into a conical shape and sealed by a bottom element of circular shape, including a forming wheel rotatable with continuous motion. The forming wheel has a plurality of peripherally distributed forming assemblies including respectively a mandrel of tubular form carried by a support member swinging around an axis parallel to said axis of rotation of the forming wheel. First feeding means is adapted to orderly collect and insert single bottom elements into corresponding forming assemblies of the forming wheel. Second feeding means is adapted to collect single blanks in an orderly manner from a store in which the blanks are stacked and to transfer them in sequence, in an extended configuration, to the corresponding forming assemblies of said forming wheel.
The machine for manufacturing disposable cups (2), comprising a side element (20), obtained from a blank of sheet material folded into a conical shape and sealed by a bottom element (21) of circular shape, comprises a forming wheel (10) rotatable with continuous motion. The forming wheel (10) has a plurality of peripherally distributed forming assemblies (12) comprising respectively a mandrel (13) of tubular form carried by a support member (14) swinging around an axis (15) parallel to said axis of rotation (11) of the forming wheel (10). First feeding means (3) is adapted to orderly collect and insert single bottom elements (21) into corresponding forming assemblies (12) of the forming wheel (10). Second feeding means (4) is adapted to collect single blanks (20) in an orderly manner from a store (25) in which the blanks (20) are stacked and to transfer them in sequence, in an extended configuration, to the corresponding forming assemblies (12) of said forming wheel (10). Folding means (50) associated with respective forming assemblies (12) is adapted to wind in a tubular form said single blanks (20) on said respective mandrels (13). Welding means (53) associated with said respective forming assemblies (12) is movable in a radial direction to said respective mandrels (13) to weld superimposed edges of said blanks (20) wound into tubular form on the same mandrels (13).

Folding means (50) is adapted to carry out the tubular winding of said single blanks (20) on said mandrel (13) of the respective forming assemblies (12).
The machine for packaging items inside relative cases (2) includes a conveyor line (10) for transporting the items to be packaged and a conveyor line (20) for transporting the cases (2) intended for packaging said items. The conveyor line (10) for transporting the items to be packaged and the conveyor line (20) for transporting the cases (2) are arranged side by side and operated with continuous motion. A transfer device (30) is capable of inserting said items in said relative cases (2). Said transfer device (30) is provided with a plurality of inserting members (40) capable of being operated in sequence on command of actuator means to make said insertion of said items in said relative cases (2).
