Description and salient technical features : CIRCOT Miniature Spinning System has been developed for assessment of spinning quality of small cotton fibre samples and for the preparation of fibre sliver and yarn samples. The system consists of four table model microprocessor controlled machines (units):
- CIRCOT Miniature Carding Machine
- CIRCOT Miniature Draw frame
- CIRCOT Miniature Sliver to Yarn Spinner
- CIRCOT Rotor OE Spinner
In each of the machines, inverter drive systems have been employed for easy settings of various processing parameters. Roller and other moving components are supported with ball/needle bearings for smooth and friction free operation. Movement of fibres during processing has been so controlled to enable faster processing of samples and for the production of quality yarn. Pneumatic suction systems have been incorporated in the ring frame, rotor spinner and carding machine and in lickerin zone for collection of broken ends/droppings. Optimised tray for guiding of lap and sliver during feeding to the draw frame and tongue-and-groove type chrome plated calendar rollers with provision for changing the trumpet bore size have been used in the draw frame.
