Device for winding yarn on test panels

The present invention relates to a Torrichtung for winding yarn on test panels having a himself * and forth moving thread distributor and provided with clamping means for collecting yarn ends of the partial turns test panel.

The device for winding yarn on test panels is known. The function of this device exists that from a number of yarn bodies withdrawn at the same time, on a test panel in depending on the relevant thread number of certain winding density

is wrapped. As far as the color is concerned, the test panel and the yarn should be in contrast, see above that light-colored yarns are wound onto black test panels and vice versa. That on the test board The wound yarn is then visually identified due to obvious irregularities or by ver are the same of the yarn windings with photographs taken under given exposure conditions Standard patterns evaluated.

The relative movement of the test panel and the yarn distributor is carried out manually or with a motor. The test panel is removably mounted in two coaxially and rotatably arranged clamping jaws, one of which by means of belt or tooth transmission with a belt pulley or a gear provided with a hand crank is coupled. The pulley or gear is on Put on the end of a guide screw rotatably mounted in the device frame. On the nut of the lead screw a thread distributor is arranged, which when the guide screw is turned from to stationary Threaded threads drawn off from the thread bodies attached to the mandrels are distributed in uniform turns on the test panel.

In the case of a motor-driven device, that is Gear attached to the end of the guide screw in engagement with the pinion of the electric motor.

About the speed of rotation of the lead screw compared to the speed of the "test panel rotation

to change, the guide ring screw can be changed by means of step washers or Focken- or ratchet mechanisms are driven with an adjustable crank or eccentric. The change in the speed of rotation of the guide screw can also be done by changing gears.

The disadvantage of these door directions is, on the one hand, that they are laborious Manipulation when changing gears, when moving the belt or when adjusting the eccentricity and the resulting the following possibility of incorrect setting of the required wind density, on the other hand the complexity the construction, if a gear box is used.

! Bel are the known construction of the device the thread body placed on mandrels, whose Axes of thread guide eyelets provided on stationary rods parallel to the axis of rotation of the test panel get lost. The yarns withdrawn from the packages "- _ go through these stationary thread guide eyelets and continue " through the eyelets of the attached to the guide screw Thread distributor through. The mandrels are on the machine frame or on the yarn distributor or on the base the device attached holders arranged; alternatively, you can also use an on on the machine frame or supports attached to the base can be attached to an adjustable shaft.

The disadvantage of this construction is that it is spatially

is demanding, the portability of the device is difficult and accidents at work or damage γόη push-on mandrels allows.

In the "known version of the test panels" clamping means are used intended to catch the ends of the individual partial turns. These are either as in.die "Screws screwed in on the side wall of the test panel or as spring-loaded screws on the side wall of the test panel arranged pins executed.

The clamping of the yarn by winding it around such a clamping means, which is designed as a screw or a pin is, is time consuming and cumbersome and creates difficulties, especially in the elimination the partial turns, from the test panel,

The invention avoids these disadvantages.

The invention consists in that the yarn distributor is stepped by means of a set of coaxially arranged and drive wheels engaging on a rail of the yarn distributor are driven so that the latter Set of drive wheels in one arranged on a drive shaft so that it can be displaced and swiveled out Fork, the vertical and horizontal position of which can be adjusted by an eccentric, is rotatably mounted, that the entire drive mechanism of the device
