Troubleshooting Jointing, Glue Spreading and Crimping

Poor Jointing

The sections of the veneer are spliced but sections
open. Slight openings found along the glue line.
Inconsistent or insufficient glue spread. Sections of the veneer
received too little glue or none.
Check the method of applying glue to the veneer.
Small slivers of the veneer were torn out along the edge. Check the jointer.

Excessive Glue Spread

A build up of glue on the surface of the veneer. Too heavy of a glue spread on the veneer. Check the method of applying glue.
Tear out of the veneer along the glue line. Build up of crystallized glue on either the upper heater strip or
lower heater bar.
Check the method of applying glue.

Crimping

The leading edge of the glue line is pushed back along
the glue line.
Build up of crystallized glue on either the upper heater strip or
lower heater bar.
Check the method of applying glue.
Lower heater bar is high. Readjust the lower and upper heater bars.
