An apparatus for cutting textile strands and forming the cut strands into bundles including a means for supplying the textile strands. A means for positioning the textile strands funnels the textile strands into a grouping of substantially parallel strands having a substantially cylindrical cross-section. A means for wrapping the parallelly arranged strands places a wrapper of paper around the strands and secures it by adhesive. A capstan guides the parallel strands to an accumulator pipe which has at its end a means for cutting the strands. The strands are held and retained so that a blade can cut them and the ends of the strands of the bundle are joined by adhesive or heat. An adhesive strip is tangentially attached to the sides of the bundles so that they may be wrapped around a rotating shaft.

Apparatus for making bundles of textile strands

A process for the preparation of texturized multifilamentary polyester yarn possessing a stable crimp, in which the yarn passes first through a crimping device comprising an injector where the yarn is subjected to a stream of hot fluid which separates the filaments, and thereafter through a stacking nozzle to cause crimping, characterized in that the fluid is fed in at a temperature below the second order transition temperature of the polyester yarn, which feeding temperature is usually between 95.degree. and 220.degree. C., and in that the stack, after it issues from the nozzle is kept in the compressed state, subjected in this state to a high pressure of the order of 20 to 200 kg/cm.sup.2, and kept at ambient temperature or subjected to a heat treatment at a temperature below the second order transition temperature of the polyester yarn, which is usually at a temperature of up to about 220.degree. C., for a period of time ranging from one minute to 150 minutes. Polyester yarn possessing a stable crimp and fiber prepared by cutting the said yarn, as well as the textile articles comprising this yarn are also disclosed.

A chair is disclosed which includes a filled seat portion and a filled back portion joined by a unitary, non-articulated semi-rigid connection integral with the seat portion and the back portion, the connection having a rebate therein, for example in the form of a step, a triangle, an arc, or a continuation thereof.

Chairs

A method for interlacing strands of a textile yarn by subjecting the yarn to a fluid current varying in direction and flow as the yarn passes through an interlacing zone under tension, and apparatus for implementing the interlacing method including an interlacing chamber having at least one element movably disposed in the interlacing chamber and movable by the fluid current to deflect the fluid current to vary the direction and flow of the fluid current.
