Abstract (en)

[origin: GB2267956A] A machine by which a rod (54) is driven into taphole clay, before it has fully hardened, and is later extracted to open the taphole, comprises a mounting, a carriage (32) which can be displaced along this mounting and a drive means for the carriage (32). Guide means (68, 70) define a guide channel (64) for the rod and have a longitudinal opening (78) giving access to inside the guide channel (64), perpendicularly to its axis. A finger (42) penetrates through the said longitudinal opening (78) to inside the said guide channel (64) to exert an axial thrust on one end of the piercing rod (54). <IMAGE>
