Yarn Evenness Tester

In our enormous array of scientific instruments, we have also added an extensive array of high performing Yarn Evenness Testers. Available in manually operated and motorized models, these testers are widely used to measures the yarn appearance on boards. Complying with industry standards, the system is comprised of a yarn wrap board and a arrangement to wrap the yarn over it at equal spacing under a desired tension.
Specification:
A yarn guide is used to wrap the yarn over a manually rotated board
This guide moves parallel to the pivoting axis of the board with the help of a screw giving uniformly spaced wraps.
With a chain and sprocket drive, the guide is positively linked of the rotation of the board
Moreover, to give five different spacing to the yarn for wrapping yarn of different counts a set of change gears are provided
A spring loaded adjustable tensioning arrangement is also attached in the system to provide the desired tension to the yarn
Built on a rigid castled base
Finished in dark gray painting and bright chrome/zinc plating to give a corrosion resistant finish
To enable evaluation of both light and dark colored yarns two numbers rectangular acrylic boards having one face white and the other face black are supplied as standard accessory
Additional boards, both rectangular and tapered are available as optional accessories
