Abstract (en)
[origin: EP2011615A2] The method involves performing molding of a lower shaft (1) in molds by a vibratory pressing process or a casting process. The lower shaft is partially-hardened after molding for a time period of 1-10 hours. The variable coagulates are molded by removing the concrete (14) using a rotary molding cutter (5) or a cutting tool (17) that is controlled by a program, where the lower shaft is present in a reverse natural layer. An independent claim is also included for a lower shaft manufacturing device.
