Small modifications on the TD-1 adhesive tape applicator head

 As a test, we made some minor modifications to the Paperfox TD-1 tape applicator head.


1. A more flexible and easily replaceable flat spring

The flat spring fixed from above (new way)

The flat spring made of thinner material can be installed from above, so there is no need to remove the adhesive tape applicator head when changing the knife. 

The flat sping fixed from below (traditional way)

Certinly the thick leaf spring can also be attached from below in the old, usual way.

The M3 D-head screw is secured against loosening with a serrated washer. The older (up to 2022) applicator roller holders were made by welding and the welding seam may prevent the flat spring from being mounted in this way.


2. More precise tape guide


After unscrewing the M6 guide screws on the standard TD-1 head, insert M5 screws through the M6 holes of the base plate, pull the bottom plate onto it, and then loosely wind the 10mm diameter cylindrical pins onto the screws. Slide the adjustable slider onto the pins, then tighten the M5 screws holding the cylinders. The adjustable slider can be fixed in the desired position with an M5 screw. If there is enough space on the machine, wing screws can also be used for this purpose.
