Supercanilla without soul (Machine-translation by Google Translate, not legally binding)

摘要

"SUPERCANILLA SIN ALMA", characterized by the fact that it consists of a kind of ball, of cylindrical shape, ending in a more or less conical tip, wound on a small truncated-conical bushing, which serves as a base and to assemble it in the shuttle, which is constituted by a rapid crossing of the thread and by a strong folding of its tip, presenting, in the center, a longitudinal step, without soul or tube, which allows it to store more material than in a tap.
