The tension of the brake on the Signature labeller is controlled by an assembly in the rear of the labeller.
Adjustments can be made to this assembly to obtain the correct/suitable working of the brake.

A good indicator for this is one of the screw holes in the back - plate is close to the top of the brake arm -
