Fig. 2 has schematically shown the development of yarn tension in the weft yarn insertion process;

Fig. 3 is the schematic sectional view of using in the weaving device shown in Figure 1 that stops element;

Fig. 4 schematically shows the insertion brake apparatus that for example uses in weaving device as shown in Figure 1.

The specific embodiment

In Fig. 1, yarn spool-holder tube of label 1 expression.One one thread 5 extends to a yarn preparation device 2 from described bobbin, described yarn preparation device 2 comprises a yarn feeding roller 3, storing yarn with the form of a plurality of coils on described yarn feeding roller 3, yarn is fed the Yarn processing device of loom 4 forms from described yarn feeding roller 3.Yarn 5 is also by being arranged on a slotting yarn brake 6 between described yarn feeding roller 3 and the loom 4.

Be one and stop element 7 that the described element 7 that stops can be configured to as shown in Figure 3 shape with the circumferential surface of described yarn feeding roller 3 is oppositely arranged.As shown in the figure, the described element that stops to be made of a housing 8, described housing 8 comprises an electric coil 9, described electric coil 9 can be connected with a voltage source (not shown), and cooperate with an armature 10, described armature can move up and down under the effect of the power that described coil 9 applies, and at it to the position that described yarn feeding roller moves, prevent that yarn 5 is from described yarn feeding roller 3 unwindings.Described armature 10 is provided with one and stops pin 11, and the latter as previously mentioned can be to described roller shifting.The described pin 11 that stops to guide in a bearing 12, and described bearing 12 is equipped with a pressure sensor 13, can measure by yarn 5 by means of this pressure sensor 13 and be applied to the described power that stops on the pin 11.Be delivered to an apparatus for evaluating 15 from the signal of described pressure sensor 13 through circuit 14, the latter is delivered to a display floater 17 by circuit 16 with described signal again.

Represent in more detail as Fig. 4 b, brake apparatus 6 is used for during weft yarn insertion process certain described yarn 5 being slowed down, this brake apparatus 6 is provided with a removable braking element 18, described braking element 18 is represented in more detail as Fig. 4 b, and can for example be a bar, described braking element is installed on the axle of a motor 19, described motor can move to different positions with described arm 18, to obtain different braking effects, wherein the power that is applied by described motor is that of described yarn power measures.Be supplied to the position of the electric current and the described displaceable element of described motor by measurement, can obtain described bar 18 and put on measuring of power on the yarn 5, thereby can obtain the measuring of tension force in the described yarn.The numerical value of described tension force is supplied to apparatus for evaluating 15 by circuit 30 similarly, and the latter passes to described display floater 17 with described numerical value by circuit 16 again, expresses to visualization described tension force subsequently at described display floater 17.

In weaving process, the multiple stage can take place, these stages show in Fig. 2 continuously.At incipient stage I, described yarn 5 still contacts with the described element 7 that stops, and is applied to the described tension force that stops on the element by yarn 5 and is presented on the display floater, and the tension force in this stage is a riser 31.At incipient stage I, (main injector) realized a specific yarn tension by the main projector, during being one subsequently, wherein said yarn passes through described loom 4 with an almost constant speed, after this terminal begin a deboost phase II constantly what yarn 5 almost arrived described shed open, brake apparatus 6 is operated and is applied a brake force by 18 pairs of yarns 5 of described braking element at this moment, and as reaction, a yarn power is applied on the described braking element 18.Described yarn power is measured by described braking element 18, and described measured value is passed to described apparatus for evaluating 14, and the latter makes it be presented on the display floater 17 with the form of crest 32 visually subsequently, and described crest has been represented the development at deboost phase II yarn tension.When the deboost phase finishes, stop phase III begins, the wherein said element 11 that stops to be pressed against on the surface of described yarn feeding roller 3, thereby prevent the further unwinding of yarn, and described yarn stops to apply on the element 11 a yarn power described, this yarn power is measured by pressure sensor 13, and measured value is passed to described apparatus for evaluating 15, and the latter is shown as a line 33 with described yarn power on described display floater 17.When described stop phase III finishes, described yarn is cut off, and cut off Phase IV, wherein yarn 5 still contacts with the described element 11 that stops, the latter measures described yarn tension force at this moment, and measured value is delivered to apparatus for evaluating 15, and the latter shows described tension force in form with a line 34 on described display floater 17 of described stage once more.In this way, for critical stage I, II, III, IV, can obtain the preferable image of described yarn tension with any speed, as shown in Figure 2.The user can notice the development of the tension force in the yarn described at any time the described critical stage.The user can change the adjusting of described device according to the information that obtains.Adjusting to described device changes and can also automatically carry out, that is, described apparatus for evaluating 15 passes through
