METHOD AND APPARATUS FOR MEASURING THE WIDTH OF COMPOSITE TAPE

摘要

Apparatus is provided for slitting composite material into tape and for measuring the width of the slit tape as the tape is being reeled onto take up rolls. The tape width is measured by an optical micrometer. The optical micrometer includes a transmitter for directing radiant energy over the tape and, a receiver for receiving radiant energy from the transmitter that passes across an edge of the tape and for producing a signal related to the width of the tape.
