摘要

A device for chopping fiber strand includes a form, and a strand feeding mechanism that delivers the strand to the form and conveys the strand along the form. First and second grinding wheels may be included to cut the strand into individual segments of desired length as the strand is conveyed along the form. A method of chopping a fiber strand includes the steps of delivering a continuous strand onto a base end of a form, conveying the continuous strand along the form from the base end toward a discharge end and cutting the continuous strand into individual segments of desired length, for example using first and second grinding wheels.
