Mishnayos Negaim Perek 11 Mishnah 9

המעלה מן הפקעת (one who winds thread from one coil to another) – sometimes when women make a coil of thread a cubit [in length] or two cubits [in length], and rolls and surrounds from one to the other to make a large coil, if before she winds all of it, a plague appears on one of them, and the thread fastens them, the second is pure.

סליל (shuttle containing the spool) – a hallow piece of wood like a species of a reed that they fasten upon it the yarn.

כובד העליונה (the upper beam from which the warp depends) – two round pieces of wood that the weaves attach on them their warp and rolls them, and the plague appears on the one beam.

השני טהור – that it was not an attachment.

וכן שני דפי לחוק (and similarly, the two wings of a shirt) – also are not an attachment. And they are not similar to tour shirts that we cut and attach to it the sleeves and the other pieces with a stitch of a complete attachment, for that is definitely considered attaching as if it is one cloth, but we are speaking that they are not attached all that much.

בנפש המסכת (the woof of the standing loom) – the thread of the woof that enters into the warp like the soul into the body, and until that settles on their defined place near that which is woven it is like the warp to combine with it to a plague like a split [Cilician] bean. Alternatively, at the outset, when he weaves in it the two portions of he web produced by passing the spool with the woof across the warp prior to weaving in it three [fingerbreadths] by three [fingerbreadths].

בשתי העומד (the standing warp) – they are the threats of the warp that are between the upper beam and the lower beam, the roller on which the web is wound as it advances, that stands there to be woven and to anoint them the threads of the woof. And this comes to tell us that it does not say that each and every thread stands on its own and that it doesn’t have the width of a split [Cilician] bean, but rather all of it is attached one to the other. But if a plague (also) appears on this side, it is impure on the other side.

אם היה רצוף (if he warp – on the loom – is joined closely – the threads being properly arranged) – that the threads are joined closely one next to the other like a cobweb/block pavement, for such is the manner of the weavers to arrange them so that their weaving is corresponding, then it is considered attachment. But if not like this, we view each thread as if it stands on its own and it is not an attachment. But the Halakha is not according to Rabbi Shimon.
