The craft of auxiliary dobby shaft is one of methods used in the traditional figured woven textiles and especially brocade in China.Based on the principle of auxiliary dobby shaft,a new method of weave design was prop...
The principle of a CAD method of converting the pre-designed figures in image form into complex dobby weaves with the appearances similar to the original figures is mainly introduced in this paper. A few designed weav...
There are two different types of dobbies used for weavingmachines,i.e.the negative and the positive ones.In or-der to compare them,a dynamic modeling analysis ishere dealt with.Since the dynamic behavior of the posi-t...
UP to now all shedding dobbies used in China are of symmetrical type. But now we are manufacturing flexi-ble rapier looms as well as shuttle looms in mass produc-tion scale. They rather demand an asymmetric shedding d...
At first, the function of Dobby (GT601) motion is analyzed, and then its speed limitation at which skips will occur because of the failure of the shedding action is worked out. At the same time, some effective measure...
In this paper,a practical new mechanism of positive typedobby for weaving is introduced.With this mechanism,the Staubll 2500 negative dobby can be converted into apositive dobby to achieve higher weaving speed through...
