Although the invention applies to barrel-shaped beaches or locations The most varied of shapes can be used, is never particularly advantageous on a flat sliver or a flat fiber pile can be used. If a fiber lor according to the is treated, it becomes wavy folded, and slight fiber damage must be expected because the counter pressure on the pile tape of the parts already folded further in front can be kept to a minimum. A fundamental difference between this KrUuseiververfahren and the under Use of stuffing boxes is determined by the crimp obtained.

The product obtained according to the invention has novel properties which distinguish it from the products according to known crimping processes and crimping devices and in particular from the fibers crimped in gland crimpers. Fibers folded according to the invention have a regular wave shape with rounded wave crests or wave crests. The individual fibers can not only be crimped or crimped in one plane, but can also be folded in three-dimensional fora or in three-dimensional helical lines. The fibers curled in gland curlers, on the other hand, are curled or folded unevenly and have sharp angles or points that are separated by straight legs ¹¹

In such a device a simple feed conveyor belt can cooperate with a fixed plate. However, it is also possible to use two feed conveyor belts which are arranged essentially parallel to one another at a tight distance ₍ moving forward at a similar speed It can be an extension of the same, but it is preferred to use two similarly moving conveyor belts running parallel to one another to remove the folded pas strand or separate as closely as possible from this inlet end.A suitable way to achieve this is to make the feed conveyor belt or belts flexible and at the outlet end over guide rollers or dfel A small radius or a small curvature, so that the outlet end of the SufuhrsyEtems can be brought very close to the inlet end of the conveyor belts used for further conveyance. For example, the last-mentioned conveyor belts can be guided over rollers or guides with a circular profile that have either a small or

a very large diameter bsw. Radius of curvature

The fibers can be fixed in their curled position as long as they are still held between two conveyor belts or other guides. In the case of synthetic fibers, the fibers can be folded in a heated state so that they only have to be cooled down for fixing. Liquid fixing agents can be added through the supply or discharge conveyor belts at places where they are permeable. If "Zolle is folded or crimped, steam is often used to fix the crimp, with or without treating the wool with a fixative." For these purposes, the conveyor belts used to remove the folded wool can be permeable and run through a steam chamber · Also Provision may be made to steam the sliver prior to crimping or folding to condition e-Ί prior to folding.

Hit the method proposed according to the invention and the corresponding devices can in contrast to the 2SU Stopfbuohienkräueelern or Stopibuoheenkrinpern the dimensions of the curvature or fold produced are proportionate loans can be controlled. The extent of the Crimping can generally be defined by two factors, namely the creep frequency, which is the number of the generated waves or folds per unit length of the iaserband is, and the Krimphohe.

If one considers the crimping height and the crimping frequency, it must be taken into account that the crimping height and crimping frequency of individual fibers removed from a fiber band crimped and fixed according to the invention are not necessarily the same as the crimping height and crimping frequency of the crimped Faeerbandos the crimp crosses of a crimped and fixed sliver of amplitude and the slope of the V'iXlbmi tmtersohledon, which were given to the sliver such as -ibon baspi'.iohiiii uraprUngLlah, the / receives * »· aiii sv / lscheu dsn Abiueasung original ö'-old and the letarfcHob f.lxlarfcsn crimping hUngfc of tier WLrkaamkeit

Nevertheless, it remains true that when crimping fibers According to the present invention, the height of the crimping can be controlled directly by the distance between the strips or the like guiding the folded fiber web. Thus, in a preferred device, the crimping height of the sliver is increased by increasing the distance between the conveyor belts used to remove the folded sliver increased * on the other hand decreased the crimping height is reduced by "reducing the distance β between the discharge conveyor belts. If the crimping height increases, the crimping frequency is reduced. However, if a given conveyor belt distance through the Krinipfrequena the speeds are controlled with which the sliver is advanced to the folding zone and removed behind this folding zone, namely duroh the ratio between the speed of the infeed conveyor belt to the speed of the outfeed conveyor belt, which can be referred to as the "infeed ratio" For a given distance between the discharge conveyor belts, more crimps of the same height are created per unit length of the sliver. The size of the crimp of the sliver can easily be changed in the operation of the machine by changing the feed ratio or the Gap between the discharge conveyor belts changed, whereby modifiable crimped slivers are obtained.

12 -009845/0460

The control iat especially with feed ratios ie range -from two: one to eight: one can be achieved. If the supply container is less than 2: 1 and the conveyor belts used for removal almost touch each other or a very narrow gap is provided between them, for example a gap of about 1.3 mm, a flat, wavy crimped fiber band is produced. When the feed ratio is increased, the back pressure on the sliver also increases, and with feed ratios of 8 t 1 or higher, sensitive fibers such as wo11 fibers suffer undesirable damage. In the case of wool fibers, the preferred feed ratio is between 3: and 6-1. It should be pointed out that the feed ratio in a certain case is always higher than the ratio of the unfolded to the folded length of the fiber edge due to conveyor belts, which depends on the frictional properties of the conveyor belts and the sliver and the friction of a fixed feed plate against the sliver, if one is used. If the feed ratio is increased at a constant speed of the discharge conveyor belts, the crimping frequency increases, and the crimping angle decreases, and the forces occurring in the fiber band and counteracting the stimulation increase. !

Other factors affecting the eruption of curvature arise from the nature and dimensions of the too folding fag first strand. Under the condition that all other conditions remain the same with one thick sliver has a greater crimping height and crimping frequency than »a thinner sliver achieves · flexible fibers Can be crimped more easily than less flexible fibers, so that with the same fixation and use of! fiber ribbons of the same height, merino fibers have a higher one KrimpfreqLuenz aeigen als Wollt von Sobafen dtr newest « crossroads, the fibers of which have a larger diameter exhibit.

When folding ribbons made of wool fibers it was found that that a distance of 1 to 5 mm between the sun drains of the crimped tapes used is satisfactory when crimping below However, for yarns in the same device, the distance is preferably 1 to 3 mm. At higher distances, yarns tend to run out to the side or to give way, so that the gey / iinscht® crimp is not reached,

Lift the daily uses of Iriapens on fibers to increase their volatility, their ability to be printed, their opacity or dioht "or su" terbes As to their handling, a fiber sliver crimped according to the present invention can also be wave-shaped because of the precisely controlled creep height and Iriapfrefaens Cover layer or cover plate can be used. Accordingly, a folded fiber tape can be attached to a fabric base, for example by means of a Satex Adhesives «! In order to achieve a boucle carpet or upholstery fabrics.

Long less and its diameter becomes larger, like Pig. 6B shows. The individual strands of multiple Yarns are designed to be helical. The length of the yarns can be cut in half, which means that the Eex number or Texsählung is doubled and the density factor can be reduced by about $ 20.

Single or multiple yarns can also be treated in such a way that individual strands of yarn from each other separated and kinked like Pig. 6 O shows. The occurrence of this effect is partly of the magnitude depending on the twist of the pad in the yarn. Low twist Yarns are kinked under conditions in which more highly twisted yarns are compressed. Crimped yarns can lose their crimp more easily than compacted yarns. As the feed ratio increases, the Uncrimping a given yarn reduces the load required, because the yarn changes from the compressed to the crimped Eorm. There is no sign that condensed or closed yarns are much stronger than

The feed conveyor belt 16 cooperates with a stationary feed plate 20 which is set against the conveyor belt 16 by springs. When advancing dee sliver 11 by the feed conveyor 16, it may - · if desired - be treated with steam, which heated the fibers to about 10O ⁰ C, to facilitate crimping. Then the strand is discharged from the conveyor belt 16 and the plate 20 and enters the inlet opening of two spaced apart permeable conveyor belts 21, which run over guide blocks 22 and 23 with an arcuate front profile, the arcuate profiled tip 24 of these blocks, for example, one Has a radius of 2 na (see Fig * 2).

The guide roller 19 and the end of the guide plate 20 lie as close as possible to the guides 22 and 23 _f , only avoiding direct contact between the feed conveyor belt, the feed plate and the discharge conveyor belts this arrangement keeps the folding zone between the feed device and the discharge device as short as possible.

The sliver 11 reaching the folding zone is folded in a wave shape in this zone and held in this form by the bands 21 while it is guided through a steam chamber 28 and then through a drying chamber 29. The drying chamber is pickled with hot air generated by a heating device 30 in order to fix the crimp at least temporarily and to dry the fiber band. Then the crimped sliver 51 arrives at the outlet end of the device where the ribbons 21 diverge.

so different materials by changing the relative or absolute speeds of the supply conveyor belt 16 and the discharge conveyor belts 21 and the distance between the latter conveyor belts can be changed as described above. When a sliver of wool fibers in the device according to FIGS. 1 and 2 is treated, can the feed ratio is between 1: 1 and 10: 1, with particularly good results being achieved when the ratio is between 5: 1 and 6: 1

To achieve permanent fixation of the crimp Chemicals such as an aqueous solution of an alkali metal or amine sulfite or chemicals can be used Bisulfite. Although the fixative will be applied can, before the sliver 11 runs through the actual folding device, the agent can also be applied when the sliver passes between the supply conveyor belt 16 and the plate 20 or between the discharge conveyor belts 21, provided that the corresponding belts or flats for this means are permeable.

A modified embodiment of the device is shown in FIG. In this example, has the feed device has two feed belts 16 and 16a instead of the one feed conveyor belt and the fixed plate according to FIGS. 1 and 2. These feed conveyor belts

16 and 16a run over drive rollers 18 and 18a and 18, respectively Guide rollers 19 and 19a of small diameter.

The discharge conveyor belts 21 are in this device also performed in another possible way, namely they run over rollers 34 and 35 with large Diameter, the ball 34 being resilient and adjustable to the distance between the conveyor belts 21 to be able to change.

Instead of Hollen, wedge pieces can also be used as guides for the supply conveyor belts, which have a have smooth rounded surface over which the belts can slide. The radius at the tips of this Pieces of provided curvature is in the range from 1 to 12 mm and preferably between 5 and 6 mm.
