1. A device (1) for use in production of a tube bundle (3) of a wound heat exchanger (100), wherein tubes (30) are wound in a plurality of tube layers (4) onto a core tube (300) running in an axial direction (z), with a plurality of webs (10) running in the axial direction (z), said webs being arranged between the tube layers (4), said device comprising:
at least one first and at least one second guide arm (40, 41), wherein the at least one first guide arm (40) is designed to be fixed to a first end section (300b) of the core tube so that the at least one first guide arm (40) projects from the core tube (300) in a radial direction (R) of the core tube (300), and wherein the at least one second guide arm (41) is designed to be fixed to a second end section (300c) of the core tube (300) so that the at least one second guide arm (41) projects from the core tube (300) in a radial direction (R) of the core tube (300), and the at least one second guide arm (41) is opposite the at least one first guide arm (40) in an axial direction (z) of the core tube (300), and in so doing runs parallel to the at least one first guide arm (40), and
wherein the at least one first and the at least one second guide arm (40, 41) are capable of holding a plurality of said webs (10) of the tube bundle (3) of the heat exchanger (100) arranged one above the other in a radial direction (R) of the core tube so each web (10) can be displaceably mounted in an axial direction (z) of the core tube (300) in the at least one first and the at least one second guide arm (40, 41).
