Abstract
A cigarette packing machine wherein an output wheel advances a number of gripping heads, each for receiving, at an input station, a respective packet with its longitudinal axis crosswise to the travelling direction of the gripping heads, and with outer longitudinal tabs open, detached from respective inner longitudinal tabs, and supported on respective folding wings carried by the relative gripping head; the output wheel feeds the packet through a gumming station, where gum is applied between each outer longitudinal tab and the relative inner longitudinal tab, and moves the relative folding wings to fold each outer longitudinal tab into a closed position contacting the relative inner longitudinal tab before the closed packet is fed to an output station (FIG. 2).
Claims17
A cigarette packing machine, the machine (1) comprising an output wheel (3), in turn comprising an input station (8) and an output station (9), and said output wheel (3) rotating about a respective axis (5) to feed a number of gripping heads (6;
- 54, 55) in a given travelling direction (22) and along a given path (P) through said input station (8) and said output station (9);
- each said gripping head (6;
- 54, 55) being engaged by a respective packet (7) of cigarettes having a longitudinal axis (10) and longitudinal minor lateral walls (13), each of which is defined by a respective outer longitudinal tab (17) and a respective inner longitudinal tab (16);
- said output wheel (3) receiving each said packet (7) at said input station (8) with the relative said outer longitudinal tabs (17) in an open position;
- each said gripping head (6;
- 54, 55) comprising folding means (36) for folding each said outer longitudinal tab (17) into a closed position contacting the relative inner longitudinal tab (16);
- the machine being characterized in that, in use, each outer longitudinal tab (16) is folded at a folding station (51) located along said path (P) downstream of said input station.
