Comentario sobre Oholot 8:4

מסכת פרוסה (the spread web – i.e., the web hanging from the transverse beam) – the threads of the warp/longitudinal direction like they are spread out in a weaver’s vessel prior to weaving the cloth. If they were spread out over an aperture in the roof looking to the ground floor that is between the house and the upper room and the defilement is below it, it protects upon the vessels that are above, but if it overshadows the corpse or on the vessels, it does not bring the defilement, for it is not considered a tent until it is woven.

The following protect [against impurity] but do not bring it: A loom [with the woof] spread out, the ropes of a bed, waste baskets, and window-lattices. The items listed in this mishnah can act as a barrier against. For instance if one of them covers the hatch between a bottom floor and an upper story, the contents of the upper story are protected. But they don't bring impurity if they overshadow both a piece of corpse and vessels. The loom has the warp spread out over it, but it can't act as an ohel till it is fully woven. The ropes of a bed are tied tight to support the mattress. The waste baskets have small holes in them, enough so that they can't act as an ohel.

וחבילי המטה (the rope-work of the bed) – ropes of he better when it the straps are drawn in bedsteads.

והמשפלות (wicker baskets carried on a pole over the shoulder) – baskets that they remove the manure In them.

והסריגים שבחלונות (and the window lattices) – network/matting that they make in the windows, interposes, for the defilement does not pass to one side. And as long as there will not be in all of them an incision like is open to a handbreadth, for an incision/hole that is open to a handbreadth brings in the defilement.
