CN2818518Y - Device for changing yarn properties - Google Patents

Abstract

The utility model relates to a device for changing yarn properties, which comprises one base, one driving device and two clamping sheets, wherein the two clamping sheets are opposite to each other and the two clamping sheets are separated by a gap which is arranged in the middle of the two clamping sheets. Yarn passes through the gap, and the conveying state is kept. The driving device is used for pushing the clamping sheets to relatively move to shorten the width of the gap in order to clamp the yarn which passes through the middle of the clamping sheets. Therefore, the movement of the yarn is instantly stopped. Since the forward motive power of original yarn is converted into the pulling force, the extension of the fixed yarn and the change of the physical properties of the fixed yarn are caused, for example, the thickness of yarn (and the sectional area of the yarn) or the change of the properties of component fiber.
