One concept for profilscrapers on edgebanders developed by Ima as alternative for high-gloss varnishes.

The duo scraper is applied to edgebanders with laser technology, such as a retrofitted Ima Combima Concept I and is especially suitable for the delicate post-processing of the profile. The goal is to let the profile seem nearly identical to the high-gloss surface, that there's no frame effect. The Duo-scraper consists of two profilscrapers. The first one leaves a tenth and is therefore the "pre-scraper". The second one takes the last touch and eliminates the white streaking, which the first one has caused.

In order to achieve a good result, card silver with a higher polishing ability is required. Usually a buffing unit follows, which is responsible for the last finish.
