摘要

The viewing device for measurement of the width of a bunch of tensioned threads juxtaposed or in bands with adjustable accuracy in terms of the objective and the position of the camera (of the order of 0.1 mm). The absolute error which affects the measurements in constant for all the widths measured. The measurement can be obtained when the band is stopped or in movement. - Optical, mechanical and electronic sub-units are involved and adaptation is possible to another machine of superior hierarchy.
