Abstract (en)
[origin: WO2022161713A1] The invention relates to a rolling tool unit (13), comprising a rolling rod (14) having a first rolling profile (15) on a first side (19) and having a second rolling profile (16) on a second side (20). The first side (19) and the second side (20) are interconnected by means of two side regions (28) each having a support structure. A support unit (17) has two support parts (44) extending in the longitudinal direction (x), which extend along the rolling rod (14) and each of which contacts the support structure of an associated side region (28). The support parts (44) are spaced apart from each other in a transverse direction (y) and support the rolling rod (14) indirectly on a base surface (42) of a base body (40). The rolling rod (14) can be arranged on the support parts (44) such that either the first rolling profile (15) or the second rolling profile (16) faces away from the base surface (42), while the other rolling profile (16) or (15) is located between the support parts (44) and the base body (40) without coming into contact with the base surface (42).
