Method for wrapping a sheet of wrapping material around a rod-shaped article or around a plurality of linearly arranged substantially cylindrical segments, either of which comprising at least one fragile segment, the method comprising the steps of:
- rotating a drum having a central longitudinal axis and a circumferential drum surface, the circumferential drum surface comprising a plurality of flutes being arranged within the circumferential surface and extending in a direction parallel to the central longitudinal axis of the drum, the circumferential drum surface further comprising respective attachment portions arranged between the respective flutes of the plurality of flutes,
- holding in the respective flute of the plurality of flutes a respective rod-shaped article or a plurality of linearly arranged substantially cylindrical segments, either of which comprising at least one fragile segment,
- holding a respective sheet of a wrapping material having an adhesive on an outer surface of the wrapping material against each respective attachment portion and separate from the rod-shaped article or the plurality of substantially cylindrical segments held in the respective flute, with the outer surface having the adhesive thereon facing away from the circumferential drum surface,
- passing the respective rod-shaped article or the respective pluralities of linearly arranged substantially cylindrical segments between the circumferential drum surface and a contact surface of a rolling device, thereby making the contact surface contact a periphery of a respective to-be-wrapped rod-shaped article or a respective to-be-wrapped plurality of linearly arranged substantially cylindrical segments, move the respective rod-shaped article or the respective plurality of linearly arranged substantially cylindrical segments out of the respective flute, and roll the respective rod-shaped article or the respective plurality of linearly arranged substantially cylindrical segments over the outer surface having the adhesive thereon of the respective sheet of wrapping material separately held on the respective adjacent attachment portion, thereby wrapping the respective rod-shaped article or the respective plurality of linearly arranged substantially cylindrical segments with the respective sheet of wrapping material,
- wherein the contact surface comprises a resiliently displaceable upper portion for moving the rod-shaped article or the plurality of linearly arranged substantially cylindrical segments out of the respective flute of the plurality of flutes, and a lower portion which is fixedly arranged for making the rod-shaped article or the plurality of linearly arranged substantially cylindrical segments roll along the contact surface and over the respective attachment portion directly adjacent to and following the respective flute, the lower portion being arranged downstream of the upper portion in the direction of rotation of the drum,
- wherein after making the resiliently arranged upper portion of the contact surface contact the periphery of the respective rod-shaped article or the respective plurality of linearly arranged substantially cylindrical segments the upper portion of the contact surface is resiliently displaced away from the circumferential drum surface thus moving the respective rod-shaped article or the respective plurality of linearly arranged substantially cylindrical segments held in the respective flute separate from the respective sheet of wrapping material out of the respective flute,
- wherein moving the respective rod-shaped article or the respective plurality of linearly arranged cylindrical segments out of the respective flute comprises providing a lip projecting from the resiliently displaceable upper portion of the contact surface towards the circumferential drum surface, the lip having a triangular cross-section, wherein a ridge of the lip projects from the resiliently displaceable upper portion of the contact surface towards the circumferential drum surface, and
- aligning the respective rod-shaped article or the respective plurality of linearly arranged substantially cylindrical segments with an empty flute in the circumferential drum surface after being wrapped, by means of two parallel arranged posts of an alignment member striking against a trailing end of the already wrapped rod-shaped article or the respective plurality of linearly arranged substantially cylindrical segments, the alignment member being arranged beneath the contact surface and being in the form of a cylindrical hub having a first set of four radially extending posts and a second set of four radially extending posts, wherein each post of the first set of four radially extending posts is respectively arranged parallel to a corresponding post of the second set of four radially extending posts, the two parallel arranged posts striking against the trailing end of the already wrapped rod-shaped article or the respective plurality of linearly arranged substantially cylindrical segments being one of the first set of four radially extending posts and the corresponding post of the second set of four radially extending posts.
