Abstract

See full text

The invention relates to the production of profiled hose nipples. The invention was based on the object of providing a method and an apparatus which allow hose nipples of the type outlined in the introduction to be produced in a simple manner such that the formation of burrs is avoided and there is no reduction in diameter. This object is achieved in that during the forming of pipe portions (1) in the apparatus (2, 7, 9) according to the invention in the region of the subsequent ring-shaped webs (4) of the nipple profile (3), the material of the pipe portion (1), at its outwardly pointing end (4), does not come into contact with the tool in the region of the parting joints (6) of the apparatus (2, 7). This can be realized by additional cavities (14) in the tool (2, 7).
