Signature labeller - brake arm - continued
Checking brake arm operation
With the brake arm in its rest position, the belt tension around the
rear boss is tight therefore keeping the label reel stationary
Pressing down on the brake arm will make the brake pivot
boss rotate and release belt tension around the brake boss.
This will allow the reel shaft to rotate.
The grip of the belt (braking force) can be increased or
decreased by moving the position of the brake pivot boss.
Loosen the cap head screw in the end of the boss and rotate
the boss to the desired position - see below.
The spring tension can also be adjusted by moving the upper
mounting position of the spring up or down.
