The A77, B77 band machines have guides for the tape on the left and right of the clay heads. On the left side, the tape is guided over a slightly running ball bearing. On the right side, on the other hand, the tape grinds over a rigid deflection bolt. The structure of the right band guidance is in principle the same as the structure of the left band guidance, only when the ribbon tour is right in the place of a ball bearing is a fixed aluminum bolt. After a few years, there is a clearly visible blind to these deflection bolts. Only the exchanging of the rigid deflection bolt can remedy a suitable ball bearing like on the left. Built for the latest findings and norms, with permanent fat for the most extreme loads. They offer a tape inlet warehouse and a ribbon bearing with suitable spa.
