Method and device for manufacturing an object (1) by spinning at least one thread (5) or band with a hardenable matrix onto a core element (4), the thread (5) or band being carried by a spool (2) which rotates in relation to the core element/object (4/1) at the same time that the spool (2) moves chiefly in one specific length direction in relation to the object (1) so that the object (1) is continuously pulled off the core element (4). In addition to the movement in the specific length direction, a back and forth movement is conducted between the spool (2) and the core element/object (4/1) over a predetermined part of the core element's/object's (4/1) length so that the thread (5) or band is applied chiefly from the object's inner surface to its outer surface while forming a 4-dimensional structure.
