FIELD: process engineering.
SUBSTANCE: invention relates to device and method for producing coiled structures, e.g. tubes and longitudinal structures. Proposed device 50 to produce coiled tubular structures 116 comprises rotary circular table 74 to support large number of rolls 78 to allow plastic deformation of strip 80 to produce coiling to form tubular structure 116 by adjoining or overlapping layers.
EFFECT: efficient clamping of previous strip layer or core to provide tight contact and better mechanical joint.
