In Paperfox adhesive tape applicators, the adhesive side of the adhesive tape runs on Teflon-containing rollers.
Adhesive tape does not stick to rollers with a high Telfon content, but these materials are not very strong and wear out quickly. The mechanical properties can be improved by adding glass fiber or graphite, but in this case the glue also adheres better to the roller. On the paperfox.eu website you can find the types of rollers produced.
Below I present a trick that can be used to increase the life of the rollers.
At the end of the tape strip, the applicator roller of the TD-1 applicator head presses the adhesive tape against the Teflon roller, and the resulting force pulls the tape against the knife, which cuts it.
The load on the Teflon rollers can be reduced to a small extent by reducing the supply pressure.
The applicator adjustment screw can be adjusted so that the applicator roller does not touch the Teflon roller.
This significantly reduces the stress on the rollers, and this solution works well for easy-to-cut adhesive tapes.
Unfortunately, when cutting in this way, the tensioning force of the tape is also reduced, which can cause inaccurate cutting especially in the case of adhesive tape made of strong material. (The edge of the knife slides over the surface of the tape before cutting it.)
A sharper knife is also available for the machine (www.paperfox.hu), which makes cutting more precise even with lower cutting force.
If the knife still does not cut the adhesive tape reliably, you can try to solve the problem by adjusting the flat spring.
