Ref. No. CFC/FIGHF/09 CFC/UNIDO/FIDA 16 Figure 9. Working model of mechanical tuxer After thorough and continuous testing, it was observed that the design improvements did not function effectively as expected. The tuxying capability of the machine was limited to softer and thinner leaf sheaths. Tougher and thicker leaf sheaths are either stuck-up between the flattener and blade mounting or passed through the knife without recovering the full width of the leaf sheaths. Difficulty in removing the short fibers accumulated at the blade was also experienced. Tuxies and waste materials mixed up at the discharge end and needed additional manpower to recover and arrange the tuxies produced. 4.2.2.4 Final model Based on the results of the test on the working model, changes were made on the final model. The machine now consists of a feeding table, guide roller, knife assembly, presser, puller, power drive, pedal, and frame assembly. A set of rollers is mounted in the feeding table to allow the leaf sheath to move freely towards the knife. This is followed by a guide roller which directs the leaf sheath to the blade assembly. A roller is mounted and pressed on top of the knife assembly. It flattens the leaf sheath as it goes through the knife. The knife then cuts and separates the outer from the inner portions of the leaf sheath as it is pulled out by two contra-rotating rollers. The whole assembly is mounted on a frame with two wheels and handle for easy transport. In operating the machine, the foot pedal is pressed down to create an opening between the presser and the puller. The leaf sheath is then inserted in the opening between the two rollers. The foot pedal is released and the tuxy is manually pulled. A 4Hp gasoline engine is used to power the machine.

Final model of the mechanical tuxer and its mobility The final model produces tuxies that are thicker with wider ends compared to tuxies produced by the traditional method. These tuxies are thinner and taper towards the end.
