PNEUMATIC DEVICE FOR AUTOMATIC CONTROL SYSTEM OF SLIVER{40 S THICKNESS

摘要

In the automatic control system of sliver's thickness wherein the thickness of sliver continuously delivered from a draft mechanism is measured by an air-micrometer and, when a portion of sliver having unacceptable thickness is detected, the draft ratio is changed so as to produce sliver having allowable variation of thickness, the measuring device of the air-micrometer is provided with a trumpet-like condensing member and a delivery cylindrical member disposed at a coaxially downstream position so that a space for embracing the sliver in pressurized air is formed between both members.
