4. If the scraping performance is still not satisfactory, it is possible to adjust the attack
angle of the knife.
This is achieved by adjusting the two set screws (906) to tilt the knife block (904) on
a greater angle causing the knife to cut more aggressively into the glue edge.
NOTE!
The scraper is designed to remove the squeezed glue bead and a small sliver of
edgeband material. If the amount of trim overhang is greater than approx 0.2mm, the
trimmer should be adjusted so the scraper is removing an appropriate amount.
This will vary depending on the band material and the flatness of the workpiece.
If the workpiece is badly distorted, it will be necessary to set the trimmers further away and
hence have the scraper do more cutting. The ability to achieve this will depend on the
materials being used.
The final adjustment for the scraper is the Travel Limiter (908). This screw is set so that
the scraper is able to travel approximately 0.5 - .0mm beyond the worksurface. If this
adjustment is set too high, the scraper will be held off the panel and not perrorm correctly.
It is designed that in the event the trimmer is pushed away from the panel by a misplaced
vacuum pod, the scraper will slide back onto the panel due to the radiused end of the
knife. If the overtravel is too great, this will not happen and the scraper knife may damge
the banding material.
