Abstract: Crimping machines comprising a stuffing chamber with a rectangular cross section and two rollers, between whose generated surfaces there is a narrow roller gap for delivering a bundle of synthetic threads, are widely used. Generally, the stuffing chamber is surrounded by smooth fixed delimitation surfaces. In operation, heat is generated as a result of the friction between the delimitation surfaces and the clump of threads located in the stuffing chamber. The novel crimping machines can operate at very high speeds without melting occurring as a result of heating caused by friction. The first roller (1) is provided at its front ends with flanged wheels (4, 5) which enclose the other roller (2) with slight play. The stuffing chamber is located in the annular duct between the flanged wheels (4, 5) such that their inner faces form two opposite delimitation surfaces over the entire length of the stuffing chamber (60) from the roller gap (3) to its mouth (61). Preferably, the mouth (61) of the stuffing chamber (60) is disposed at a spacing from the plane (62) of the roller gap (3), namely on the side on which the first roller (1) is located. The two rollers (1, 2) are equipped with motors (19, 22) which are designed for a peripheral speed of the rollers (1, 2) of up to at least 1000 m/min.

Abstract: Feed rollers (30) advance the textile fibres (20) into a stuffer box (10). The width (w) of the entry aperture (8) of the stuffer box (10) is one millimetre for each fibre bundle having a linear density in the range of 200 to 750 denier and the height (h) is between 2 and 20 mm. A lid (12) is held down by a pneumatic cylinder (40) until the pressure of the material accumulating in the stuffer box forces up the lid and the crimped material (22) then escapes from the stuffer box.

Abstract: Crimp can be generated in lyocell fibre (19) by passing the wet fibre through a compaction device such as a stuffer box (32) fed with steam (37A). The method provides some permanent crimp, which is of advantage for example during processing into spun yarn. The method can be used to introduce high levels of crimp, which is of advantage for example in the manufacture of filter rods.

Abstract: This invention is directed to a method and apparatus for heat-treating multifilament yarn, wherein the yarn is fed into a chamber having imperforate and perforate sections, and to the resultant yarn products. Hot fluid is forced through a wad of the yarn in the imperforate section of the chamber and vented through the perforate section. The device may be used to bulk and heat-set yarns, depending upon the operating conditions. Yarn products prepared from this process are especially suitable for making carpets having good texture retention and carpet bulk.

Abstract: The present invention relates to a process for texturing a ply-twisted, crimped, multifilament yarn, a yarn made by this process, a carpet made from this multifilament yarn. The present invention also relates to a method of image analysis for analyzing the texture of a surface, and to a saxony-type carpet having a tightly tailored surface texture characterized by this method. The process of texturing a yarn comprises adjusting the temperature and moisture content of the yarn prior to passing the yarn through a stuffer box. The method for analyzing the texture of a surface employs a model based on a second order cooccurrence matrix model which calculates a set of textural parameters for image classification. In one embodiment, the method compares an unknown sample of a saxony-type carpet to a goal sample of a saxony-type carpet having a tightly tailored surface texture to determine whether the unknown sample is such a carpet.

Abstract: In known stuffer boxes one of the four wall plates enclosing the stuffer box is in the form of a pressure plate which is pivotable about the axis of one of the two rolls which are used to feed the yarn bundle. During operation the pressure plate is pressurised by a pressing force. The yarn material enclosed in the stuffer box exerts a back-pressure on the pressure plate. This results in a force of reaction on the bearing of the roll, which force is dependent on the operational state and the point of application of the pressing force. This leads to fluctuations in the normal force which is exerted on the yarn bundle by the rolls, resulting in uneven crimping. The invention relates to a new device in which the point of application of the pressing force can be moved by an adjustment member (15). A control loop, which comprises a force measurement sensor (17) for the reaction force acting on the roll (2), adjusts the reaction force to zero by actuating the adjustment member (15).

Abstract: The invention is directed to a process for producing bulked synthetic multifilament yarn comprising a plurality of continuous synthetic filaments having deposited thereon at intermittent intervals an adhesive polymer component having a melting temperature below that of the continuous synthetic filaments. The process comprises texturizing synthetic multifilament yarn to obtain desired bulk characteristics by directing heated yarn in a current of heated fluid against a yarn plug contained in a texturizing chamber, applying said ahdesive polymer component in a molten condition to the surface of said yarn plug, and continuously discharging texturized yarn from said texturizing chamber at a lower linear rate than the feed rate of said yarn to said texturizing zone while said adhesive polymer component is still in a molten but solidifying state, resulting in bulked synthetic multifilament yarn having the adhesive polymer component deposited thereon at intermittent intervals.
