Yarn texturing

Claim 1

Apparatus for texturing yarn comprising: means forming a first passage through which yarn to be textured can be directed, said first passage having an inlet and an outlet for the yarn; means forming a second passage of greater cross-sectional area at the outlet thereof than at the inlet, the inlet of said second passage being connected to the outlet of said first passage; conduit means communicating with the inlet of said first passage to introduce a fluid; a chamber having an inlet and an outlet, the inlet of said chamber being connected to the outlet of said second passage; and a plurality of alternate first and second layers of rods disposed in said chamber in stacked relationship, each first layer comprising first and second curved rods spaced from one another so that a yarn wad extending from the inlet toward the outlet of said chamber extends between the first and second rods, each second layer comprising third and fourth straight rods spaced from one another so that said yarn wad extends between the third and fourth rods, said first layers having the first and second rods thereof aligned relative to one another so that rods of the second layers tend to move by gravity downwardly and inwardly along the first and second rods immediately therebelow toward the center of the chamber when the apparatus is positioned so that the chamber is located vertically above said second passage.
