Yarn Appearance Board Winder

Visual determination of unevenness along the length of a yarn is carried out by wrapping it in equally spaced parallel wraps over a board and comparing the appearance of irregularities against standard rating photographs. To enable yarns of different thickness to be assessed, the spacing between the wraps is suitably selected so as to give a clearly distinguishable pattern.

The 'INNOLAB' Yam Appearance Board Winder consists of a yarn wrap board, and an arrangement to wrap the yarn over it at equal spacing under a desired tension. The board is rotated manually to wrap yam over it. The yarn is guided on to the board through a yarn guide which moves parallel to the pivoting axis of the board with the help of a screw giving uniformly spaced wraps. The guide is positively linked to the rotation of the board with the help of a chain and sprocket drive. A set of change gears gives five different spacing to the yarn for wrapping yarn of different counts. A spring loaded adjustable tensioning arrangement provides the desired tension to the yarn.

The equipment is built on a rigid casted base. It is finished in off white synthetic stoving enamel paint and bright chrome / zinc plating to give it a corrosion resistant finish.

Two number rectangular acrylic boards having one face white and the other face black to enable evaluation of both light and dark coloured yarns are supplied as standard accessory. Additional board, both rectangular and tapered, are available as optional accessories
