The first step to which the yarn is submitted
to become a fabric is the warping.
Unrolled by its own distaffs
and placed one next the other in the longitudinal direction,
the yarns shape the warp of a canvas
in the breadth wanted
and are winded up on the beam of the loom,
that is a metal cylinder, in the case of our modern looms,
and the warp, paying attention to wind it up
in the most orderly way and with the same tension.
