Definitions
- the invention relates to a device for producing thick / thin effects in a filament yarn, which is drawn in at least one stretching field, each delimited by an input delivery unit and an output delivery unit, one between the input delivery unit (6) and the output delivery unit (6 ') the filament yarn (1) in the stretching field is arranged in the form of a heating element in contact with the filament yarn (20.1) and means for interrupting the heat supply are provided, according to patent no. (patent application 195 29 315.0-26).
- a mechanical device for lifting the filament yarn from a fixed heating device in the stretching field on defined sections during stretching is delimited by two godet / laying roller combinations, between which the aforementioned mechanical device and the stationary heating device are arranged.
- the stretching field can also be delimited on at least one side by a pair of delivery rollers (with bottom / top roller).
- the object of the present invention is to develop the above-mentioned device in such a way that the filament yarn transfers heat in the two loadings. states of action (warmed and not warmed) are deflected differently as little as possible.
- the heating surface of the heating element acting on the filament yarn is formed as the circumference of at least one disk driven via an axis of rotation with a radius which is reduced in at least one region with respect to the axis of rotation. According to the invention, it is thus proposed not to move the filament yarn, but the heating element.
- the disc and the thread run are arranged so that the filament yarn touches the circumference of the disc, so that touching the indentation does not follow the reduced radius of the disc.
- This area remains in the filament yarn as a thick effect.
- Thread speed, speed of the disc and number of areas with reduced radius of the disc determine the number of thick spots along the filament yarn.
- the length of the indentation ie the area of the reduced radius, is determined in connection with the thread running speed and the speed and the thickness of the disc the length of the thick spots. Regardless of the number of thick spots along the filament yarn, the length of the thick spots can therefore only be changed by changing the length of the areas of reduced radius along the circumference of the disk.
- the disk is advantageously interchangeable with a radius of a reduced length along the circumference of the disk.
- two disks can be arranged at a mutual distance and can be driven, for example, independently of one another by speed.
- a disk consists of two or more partial disks which can be rotated relative to one another with their respective regions with a reduced radius.
- the axis of rotation of the disk can be at least approximately parallel to the running direction of the filament yarn.
- a construction can also be used in which the axis of rotation of the disk lies in a plane which at least approximately forms a right angle with the running direction of the filament yarn.
- panes can be heated by at least one stationary heating device arranged in the immediate vicinity via convection, radiation or induction.
- FIG. 3 shows another embodiment of the invention in a schematic side view
- FIG. 4 shows a plan view of a disk consisting of two partial disks.
- FIG. 1 shows a device for producing thick / thin effects in a filament yarn 1.
- the stretching field can also be delimited on at least one side by a pair of delivery rollers (with bottom / top roller).
- this stretching field I there is a heating element 20.1, which consists of a disk 60 and a stationary heating device 62 arranged in the immediate vicinity thereof.
- the pane can be heated by convection and / or by radiation.
- the disk 60 is driven by a motor 61 via an axis of rotation 65.
- the circumference U of the heated disk 60 serves as a heating surface for the filament yarn
- the disk 60 also being designed with a region of reduced radius R with respect to the axis of rotation 65.
- This area R with a reduced radius thus forms an indentation which does not touch the filament yarn, so that it remains cold and accordingly is not stretched. This results in a thick spot in the filament yarn.
- the filament yarn is stretched over the circumference U of the rotating, heated disk 60.
- the disk 60 can also have a plurality of indentations R and indentations of different lengths in the circumferential direction, which can also be randomly distributed around the circumference. This means that any number, length and distribution of thick spots along the filament can be achieved.
- the embodiment shown with separate drives of the disks is preferred because a greater randomness of the distribution of the thick spots can be achieved thereby.
- a desired random distribution of the thick spots along the filament can be achieved by different and alternating speeds of the two disks 60 and 60 '.
- a heating device 62 is located between the two disks 60 and 60 'and heats both.
- each of the panes can also have its own heating device.
- Each of the disks 60 and 60 ' can be designed analogously to the embodiment according to FIG. 2, for example with regions R twisted relative to one another, in which the filament yarn 1 is not touched.
- FIG. 4 A further embodiment of the invention is shown in FIG. 4: Here, a disk 60 ′′ is used, which consists of two partial disks 60.1 and 60.2 which can be rotated relative to one another with their respective areas with a reduced radius R ⁇ and R 2 .
- Both dividing disks 60.1 and 60.2 have a common axis of rotation 65. Furthermore, an elongated hole 67 is provided, which is penetrated by a clamping screw 68. It is thus possible to rotate the two indexing disks 60.1 and 60.2 against one another and thus to adjust the areas with a reduced radius R, and R 2 accordingly.
- the length of the thick spots generated can be set just as by - different - speed of the disks 60, 60 '.
- the axis of rotation 65 of the disks 60 or 60 'or 60' ' is at least approximately parallel to the running direction of the filament yarn.
- the axis of rotation of the aforementioned disk lies in a plane which forms at least an approximately right angle with the running direction of the filament yarn 1.
- or R 2 of the disk determine the number of thick spots along the filament yarn.
- the length of the indentation along the circumference of the disk also determines the length of the thick spots in connection with the thread running speed and the speed as well as the thickness of the disk.
- Filament yarn 1 only affects the circumference of the respective disk, its deflection is advantageously by touching the
- the circumference U or not touching the respective indentation is deflected only to a slightly different extent and is not stimulated to vibrate.
- the rotational speed of the disk or disks can be changeable, for example at random, in order to achieve a random distribution of the thick spots along the filament yarn 1.
- the disk or disks have more than one area with a reduced radius; moreover, several such regions can be distributed in the circumferential direction of different lengths and / or randomly along the circumference.
- the heating element there is also the possibility of directly heating the pane itself and for doing so without the heating device 62.
