There is very little information about ArtKnitter machines and their accessories and add-ons.
Below are the pictures of one of the rare ArtKnitter ribbes: Art Rib Knitter. Judging by the look, it might be compatible with the ArtKnitter RK-10 or ArtKnitter RK-18 machines.
From the look, it seems to be manufactured in the late 1950s or early 1960s.
Some information points that ArtKnitter were manufactured by an Indian company, Simac (I saw it on the front page of brochure of the ArtKnitter DX-2000 manual). However, I see on many ArtKnitter machines logos “MADE IN JAPAN”.
Enjoy the pictures below while I am scouting for more information.
