| Troubleshooting Overlapping | ||
The edge of one piece of veneer is on top of the other. The veneer is not being held flat. | The pressure bar may be too high. | Check the float gauge. |
The front suspension bolt is too tight. This lifts the infeed end of the upper heater bar. | Loosen the suspension bolt. | |
Upper heater bar is too high. | Reset the upper heater bar. | |
The front end of the heater strip is not against the lower heater bar. | Place a slight bend in the heater strip 4" from the infeed end. | |
The heater strip will not "float" up and down at the infeed end. | Check the lower heater bar for level. The feed chains are pulling on the heater strip. | |
The pressure setting is too light.Check for pressure marks, the shine, on the veneer. | Increase the pressure setting. | |
The veneer overlaps before entering the feed chains. | The holddown springs on the matching roll are not holding the veneer flat. | Lower the holddown assembly. |
Replace the holddown split springs. | ||
The matching rolls pull the veneer into the machine at angles. | Readjust the cant on the matching rolls. | |
Reduce the pressure on the matching rolls. | ||
The edge of the veneer curls up against the infeed guide. | Readjust the cant on the matching rolls. | |
If the veneer is curled at the edge set the holddown block as close to the matching roll and as low as is possible. | ||
The jointed edges of the veneer are not square. | Check the jointer blade for sharpness. Only use the veneer edge from the flat side of the Guillotine. | |
The veneer overlaps on one or both ends only. | The edges of the veneer are not straight or parallel. | Check the jointer. |
