Abstract
The apparatus for shaping substantially flat continuous material comprises a shaping device (500) for gathering substantially flat continuous material transverse to a longitudinal direction of the continuous material to form a gathered continuous material. The apparatus further comprises a cooling device (75) for cooling the gathered continuous material. The shaping device and the cooling device are combined such as to immediately cool the gathered continuous material.
Claims24
Apparatus for shaping substantially flat continuous material, the apparatus comprising:
- a shaping device for gathering substantially flat continuous material transverse to a longitudinal direction of the continuous material to form a gathered continuous material;
- a cooling device for cooling the gathered continuous material, wherein the shaping device and the cooling device are combined such as to immediately cool the gathered continuous material, wherein the shaping device comprises at least a static shaping element, static with respect to a transport direction of the substantially flat continuous material, wherein the static shaping element is a garniture tongue for shaping a rod-shaped gathered continuous material, wherein the cooling device is arranged next to an outlet opening of the garniture tongue, and wherein the cooling device comprises a contact surface for contacting the rod-shaped gathered continuous material.
Apparatus according to any one of the preceding claims, wherein a further static shaping element is provided, which further static shaping element is constructed as at least one structured surface, wherein the structure has a longitudinal extension in a transport direction of the substantially flat continuous material.
Apparatus according to any one of the preceding claims, wherein the shaping device comprises a dynamic shaping element capable of performing a movement in a transport direction of the substantially flat continuous material.
Apparatus for shaping substantially flat continuous material, the apparatus comprising:
- a shaping device for gathering substantially flat continuous material transverse to a longitudinal direction of the continuous material to form a gathered continuous material;
- a cooling device for cooling the gathered continuous material, wherein the shaping device and the cooling device are combined such as to immediately cool the gathered continuous material, wherein the shaping device comprises dynamic shaping elements capable of performing a movement in a transport direction of the substantially flat continuous material, wherein at least two different dynamic shaping elements are arranged subsequently and at a distance to each other along the transport direction of the substantially flat continuous material.
Apparatus according to any one of the preceding claims, further comprising a parting unit for creating an open channel in the gathered continuous material, the parting unit comprising a parting element, which is arranged relatively movable to a transport direction of the substantially flat continuous material and such as to extend at least partly into the gathered continuous material.
Method for shaping a substantially flat continuous material, the method comprising the steps of:
- providing a substantially flat continuous material;
- gathering the substantially flat continuous material by means of a static shaping element in a lateral direction to form a gathered continuous material;
- cooling the substantially flat continuous material immediately after gathering the substantially flat continuous material, thereby cooling the gathered continuous material by a cool contact surface in contact with the gathered continuous material arranged next to an outlet of the static shaping element.
Method for shaping a substantially flat continuous material, the method comprising the steps of:
- providing a substantially flat continuous material;
- gathering the substantially flat continuous material in a lateral direction by means of at least two subsequently arranged dynamic shaping elements to subsequently form a gathered continuous material;
- cooling the substantially flat continuous material while gathering the substantially flat continuous material or immediately after gathering the substantially flat continuous material, and
- arranging the at least two dynamic shaping elements at a distance to each other along the transport direction of the substantially flat continuous material, wherein the at least two dynamic shaping elements are arranged or comprise shaping structures such that the continuous material is gathered to a different extent by the two dynamic shaping elements.
