One is progressive cartographic generalization and the process is controlled by structure line;the other is that generalized contours come from a more simplified TIN;the characteristic points selected from contours by Douglas algorithm can be used to create the TIN.

Conclusion is made that new spinning technology should be based on hi-velocity,hi-robotization,hi-automation,large package,wide application of raw material,seperation of twisting from winding,minimization of twisting trangle section,improvement of yarn structure,reduction of hairiness.

Contrast analysis is done to the domestic cotton spinning frame equipped with the self-developed centralizing device with double suction grooves for the cotton yarn of same fineness regarding yarn structure and property of yarn produced in compact-siro spinning process under the same condition.

However, the researching work on the spinning mechanism of compact spinning technology and its yarn structure is very little for its short developing history.

It also defines the main specification parameters such as yarn construction, yarn specification, fabric specification etc and their influence over the product style, product quality and production process and advances thc concrete ways of determining the fabric specification parameters.

On-line measurement of axis of part based on technology of linear structured light;

For polynomial fitting measuring model of a linear structured light scanning probe,the extraction and compensation methods for systematic errors of the probe are presented.

A 3D shape acquisition system using linear structured light scan is introduced.

The paper introduces PrintForm HR forming wire—the newest product developed by Voith Paper Fabrics with the emphasis on the warp & weft set,weft yarns and the effect in production.
