Signature Back Fold Sensor Alignment

Proper Back Fold Sensor Alignment on Your Signature Folder Gluer

When it comes to maintaining peak performance on your Signature Folder Gluer, one small adjustment can make a big difference — the back fold sensor. This component plays a crucial role in ensuring precise and efficient folding, and an incorrect sensor position can lead to unnecessary wear, noise, and performance issues.

The Correct Sensor Setup

For optimal operation, the carton must lay as flat as possible when passing under the back fold sensor. This ensures accurate detection and smooth, consistent folding.

The correct position on Signature folder gluers is 65 mm from hook to eye. This distance ensures the sensor communicates accurately with the system, allowing the back fold mechanism to function properly.

Warning Signs of Improper Placement

If the sensor is even slightly out of position, the machine will start to show early signs that something is not right. One of the most common indicators is a thumping sound during operation. This noise occurs when the system exerts more force than necessary to complete the fold. A clear signal that the sensor needs adjustment, or your settings may be off. Ignoring this early warning can lead to premature component wear or unnecessary downtime.

Quick Check

Confirm sensor is reading on a flat surface
