Pile textile elements are disclosed in which heat fusible textile filamentary materials are assembled in a bundle wrapped in a plastic envelope. The filaments are held together at one end only of the bundle by fusing the ends of the filaments and the plastic envelope while they are in contact, under pressure, with a heated flat surface. The fused end of the bundle forms a base to facilitate handling of the pile textile element, and also facilitating securing the element to a suitable backing, such as a textile backing, furniture, bedding, etc., in a conventional manner.

Pile textile elements with fused wrapper and base

Apparatus for treating filamentary products, such as yarn, includes advancing the yarn in a groove, which has orifices opening in the bottom thereof, and which communicate with a channel through which a fluid is expelled. The channel lies in the wall of a cylindrical static body and is tangent to the inner wall of said body. The fluid supports the strand so that the yarn does not touch the groove. In addition, the fluid treats the yarn and helps to advance the yarn.

An apparatus for processing yarn in order to texturize and cut the yarn includes means for using a fluid to direct yarn into a tube which has a rotating spindle therein around which the yarn forms a wad. At least part of the fluid is exhausted from the tube and the wad is then cut and removed from the spindle.

Apparatus for simultaneously texturizing and cutting continuous yarns

Methods of and apparatus for processing yarn in order to texturize and cut the yarn include using a fluid to direct yarn into a tube having a rotating spindle therein around which the yarn forms a wad. At least part of the fluid is exhausted from the tube and the wad is then cut and removed from the spindle.
