The tape brake is electrically controlled to give the correct tape tension. The brake applies tension to the tape before it enters into the forming tools. This braking tension is enough to give the metallic tape a small elongation that is necessary to avoid wrinkles in the overlap.
The required tape tension depends on the cable size, tape dimensions and quality. For optimum results a constant tape tension must be maintained.
The brake can be mounted either on a separate stand, directly onto the accumulator or directly onto the tape pay-off BAVR94 series.
