The Production Practice of Comber Adding Auto-levelling Device
In order to stabilize the weight unevenness and weight deviation of the combed sliver,from the aspects of the adhesion of combing feeding cotton lap and layer,the difference between the eye difference and the stage difference of the dropping cotton rate of the comber,the tem-perature and humidity change of the combing shop,the lack sliver of the comber stage surface and drafting broken end and so on,the influence on the weight unevenness and weight deviation of combed sliver is described in detail,and the application effect of adding auto-levelling device in comber is discussed.The combed sliver,drawing sliver and fabric indexes are compared and analyzed before and after adding auto-levelling device in comber.It is pointed out that adding auto-levelling device in the combing process is an effective method to control the large fluctua-tion of the weight unevenness and weight deviation of the combed sliver,which is helpful to im-prove the weight unevenness and weight deviation of the cotton sliver in the post-working process and to control cotton yarn defects and fabric defects.It is also necessary for the online control of the comber,spinning automation and digital,and intelligent control.
