The first Cadfil T winding was made for the chemical industry back in 1989! The programs shown were fully developed in the Cadfil software. The winding program shown with Kevlar was showcased on the BSD stand at the K show Dusseldorf (K89). A number of patterns are required to full cover the Tee. It is possible also to wind without cross the ends but the pattern possibilities and wind angles become more limited.
