Figure 9. Work<strong>in</strong>g model of mechanical tuxer<br />
After thorough and cont<strong>in</strong>uous test<strong>in</strong>g, it was observed that <strong>the</strong><br />
design improvements did not function effectively as expected.<br />
The tuxy<strong>in</strong>g capability of <strong>the</strong> mach<strong>in</strong>e was limited to softer and<br />
th<strong>in</strong>ner leaf sheaths. Tougher and thicker leaf sheaths are ei<strong>the</strong>r stuck-up<br />
between <strong>the</strong> flattener and blade mount<strong>in</strong>g or passed through <strong>the</strong> knife<br />
without recover<strong>in</strong>g <strong>the</strong> full width of <strong>the</strong> leaf sheaths. Difficulty <strong>in</strong> remov<strong>in</strong>g<br />
<strong>the</strong> short fibers accumulated at <strong>the</strong> blade was also experienced. Tuxies and<br />
waste materials mixed up at <strong>the</strong> discharge end and needed additional<br />
manpower to recover and arrange <strong>the</strong> tuxies produced.<br />
4.2.2.4 F<strong>in</strong>al model<br />
Based on <strong>the</strong> results of <strong>the</strong> test on <strong>the</strong> work<strong>in</strong>g model, changes<br />
were made on <strong>the</strong> f<strong>in</strong>al model.<br />
The mach<strong>in</strong>e now consists of a feed<strong>in</strong>g table, guide roller, knife<br />
assembly, presser, puller, power drive, pedal, and frame assembly. A set of<br />
rollers is mounted <strong>in</strong> <strong>the</strong> feed<strong>in</strong>g table to allow <strong>the</strong> leaf sheath to move<br />
freely towards <strong>the</strong> knife. This is followed by a guide roller which directs <strong>the</strong><br />
leaf sheath to <strong>the</strong> blade assembly. A roller is mounted and pressed on top of<br />
<strong>the</strong> knife assembly. It flattens <strong>the</strong> leaf sheath as it goes through <strong>the</strong> knife.<br />
The knife <strong>the</strong>n cuts and separates <strong>the</strong> outer from <strong>the</strong> <strong>in</strong>ner portions of <strong>the</strong><br />
leaf sheath as it is pulled out by two contra-rotat<strong>in</strong>g rollers. The whole<br />
assembly is mounted on a frame with two wheels and handle for easy<br />
transport. In operat<strong>in</strong>g <strong>the</strong> mach<strong>in</strong>e, <strong>the</strong> foot pedal is pressed down to create<br />
an open<strong>in</strong>g between <strong>the</strong> presser and <strong>the</strong> puller. The leaf sheath is <strong>the</strong>n<br />
<strong>in</strong>serted <strong>in</strong> <strong>the</strong> open<strong>in</strong>g between <strong>the</strong> two rollers. The foot pedal is released<br />
and <strong>the</strong> tuxy is manually pulled. A 4Hp gasol<strong>in</strong>e eng<strong>in</strong>e is used to power <strong>the</strong><br />
mach<strong>in</strong>e.
