Method and apparatus for shaping substantially flat continuous material

Apparatus for shaping substantially flat continuous material having a glass transition temperature of below 150 degree Celsius, 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, the substantially flat continuous material having a glass transition temperature of below 150 degree Celsius;
• 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, wherein the cooling device comprises a contact surface for contacting and thereby cooling the rod-shaped gathered continuous material, and wherein the contact surface has a concave shape and the shape of the contact surface varies along the length of the cooling device;
• 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.
