Feliciano G. Sinon ABSTRACT A multi-stranded yarning machine was designed to produce a material comparable with the “tinagak” yarn. The prototype was fabricated using locally available materials at NARC, VSU, Baybay City, Leyte. Modification activities were done to improve some perceived problems in the mechanical timing device, locking mechanism, and clutching assembly. Mechanism of the …
