Abstract
A manufacturing machine and a manufacturing method for the production of a tubular element, in particular for a smoking article. There are provided: an input conveyor, which moves at least one pocket along an input path; a wrapping conveyor, which moves at least one spindle, which has the shape of an inner cavity of the tubular element, along a wrapping path; a feeding station, where the pocket receives a wrapping sheet; and a transfer station, where the pocket releases the wrapping sheet to the spindle folding the wrapping sheet around the spindle into a “U” shape.
Claims15
A manufacturing machine (8) for the production of a tubular element (1) for a smoking article;
- the manufacturing machine (8) comprises:
- an input conveyor (9), which moves at least one first pocket (11) along an input path (P1);
- a wrapping conveyor (16), which moves at least one spindle (18), which has the shape of an inner cavity of the tubular element (1), along a wrapping path (P2);
- a feeding station (S1), where the first pocket (11) receives a wrapping sheet (3);
- and
- a first transfer station (S3), where the first pocket (11) releases the wrapping sheet (3) to the spindle (18) folding the wrapping sheet (3) around the spindle (18) into a “U” shape;
- wherein the first pocket (11) has a holding wall (12), which is designed to hold the wrapping sheet (3) through suction and has, at the center, a groove (13), which reproduces in negative the shape of the tubular element (1);
- and
- wherein a relative movement between the first pocket (11) and the spindle (18) is caused in the first transfer station (S3), wherein the spindle (18) pushes the wrapping sheet (3) into the groove (13) of the holding wall (12), thus allowing the wrapping sheet (3) to be folded around the spindle (18) into a “U” shape.
A manufacturing method for the production of a tubular element (1) for a smoking article;
- the manufacturing method comprises the steps of:
- moving, by means of an input conveyor (9), at least one pocket (11) along an input path (P1);
- moving, by means of a wrapping conveyor (16), at least one spindle (18), which has the shape of an inner cavity of the tubular element (1), along a wrapping path (P2);
- feeding, in a feeding station (S1), a wrapping sheet (3) to the pocket (11);
- and
- releasing, in a transfer station (S3), the wrapping sheet (3) from the pocket (11) to the spindle (18) folding the wrapping sheet (3) around the spindle (18) into a “U” shape;
- wherein the first pocket (11) has a holding wall (12), which is designed to hold the wrapping sheet (3) through suction and has, at the center, a groove (13), which reproduces in negative the shape of the tubular element (1);
- and
- wherein a relative movement between the first pocket (11) and the spindle (18) is caused in the first transfer station (S3), wherein the spindle (18) pushes the wrapping sheet (3) into the groove (13) of the holding wall (12), thus allowing the wrapping sheet (3) to be folded around the spindle (18) into a “U” shape.
