Abstract
A method and wrapping unit for producing a package containing a group of cigarettes, and which include: feeding the group of cigarettes along a path; feeding a sheet of wrapping perpendicularly to the path of the group of cigarettes; feeding a tubular spindle along the path of the group of cigarettes to intercept the sheet of wrapping and fold the sheet of wrapping into a U about the tubular spindle; and feeding the group of cigarettes through the tubular spindle to slide the sheet of wrapping off the tubular spindle and apply the U-folded sheet of wrapping to the group of cigarettes.
Claims17
A method of producing a package (1) containing a group (2) of cigarettes;
- the method comprising the steps of:
- feeding the group (2) of cigarettes along a path;
- feeding a sheet (6) of wrapping perpendicularly to the path of the group (2) of cigarettes;
- feeding a tubular spindle (49) along the path of the group (2) of cigarettes to intercept the sheet (6) of wrapping and fold the sheet (6) of wrapping into a U about the tubular spindle (49);
- feeding the group (2) of cigarettes through the tubular spindle (49) to slide the sheet (6) of wrapping off the tubular spindle (49) and apply the U-folded sheet (6) of wrapping to the group (2) of cigarettes;
- and
- moving a movable folding member with respect to the tubular spindle (49) to complete folding the sheet (6) of wrapping into a U on the tubular spindle (49).
A wrapping unit for producing a package (1) containing a group (2) of cigarettes;
- the wrapping unit (12) comprising:
- a feed device (52) for feeding the group (2) of cigarettes along a path;
- a feed station (33) for feeding a sheet (6) of wrapping perpendicularly to the path of the group (2) of cigarettes;
- a tubular spindle (49) which is fed along the path of the group (2) of cigarettes to intercept the sheet (6) of wrapping and fold the sheet (6) of wrapping into a U about the tubular spindle (49);
- wherein the feed device (52) feeds the group (2) of cigarettes through the tubular spindle (49) to slide the sheet (6) of wrapping off the tubular spindle (49) and apply the U-folded sheet (6) of wrapping to the group (2) of cigarettes;
- and
- a movable folding member to complete folding the sheet (6) of wrapping into a U on the tubular spindle (49).
