## The feeding process

- The screws are filled into the Screw Container via the Filling Hatch.

- From the Screw Container, the screws reach the Step Conveyor Unit and are transported upwards via movable steps.

- The screws fall into the V-block of the Linear Guide (hanging from the collar), where they are guided into the Separating Unit.

## The separation process

- When a screw is required in the Screw Feeding Tightening Module, a single screw is separated out from the fasteners aligned on the Linear Guide.

- The separated screw is blown into the Screw Feeding Tightening Module.
