Holding device for holding band material in contact with support, has pressure application unit for applying plating pressure to band material for pressing band material against support during shaping of opening of band material

摘要

The device (21) has a pressure application unit for applying a plating pressure to a band material (1) for pressing the band material against a support (18), where the pressure is generated during the shaping of an opening of the band material, and the movement of the band material is authorized in the pressure application unit. A freely rotatable bearing (23) is intended to rest against the band material to maintain the band material against the support. A resilient return member (27) of the bearing holds the band material against the support in a lower position. Independent claims are also included for the following: (1) a tool for tapping openings of a band material (2) a method for tapping openings of a band material.
