Ref. No. CFC/FIGHF/09 CFC/UNIDO/FIDA 22 The extraction of abaca fiber using the autofed decorticating machine observed the following work flow: 3 hauling of stalks 2 drying of fiber 4 splitting of leafsheaths 1 delivery of fiber for drying 2 feeding of materials 1 gathering of fiber Figure 16. Work flow in the extraction of abaca fiber using autofed decorticating machine The figure above each work unit represents the number of laborers needed for each phase. As such, a total of 13 laborers will be employed to operate the autofed decorticating machine continuously for 8 hours. Figure 17. Decorticated abaca fiber (L) being dried under the sun and (R) in hanks 4.3.5 Performance of autofed decorticating machine For the first set of 400 stalks, 9.5 days were spent to decorticate 5.600 kgs of abaca stalk. On the first day (September 03), stoppages were experienced due to slippage of materials and too much wetting of the belt from abaca sap, which resulted to very low production of 2.85 kgs. In an effort to correct the slippage of material, the existing drive pulley was dismantled and sent to machine shop for modification. Grooves were added to control the wetting of and add traction to the belt and thus improve conveyance of materials to the second drum. This modification reduces the slippage of materials. On September 07, spur gear broke down. It was replaced the following day. On Sunday, September 12, auxiliary drive was installed and this prevented the stoppage of the machine due to the wetting of the conveyor belt. Set 2 took 2 days and an hour to decorticate 4,920 kgs of abaca stalks. Higher speed was tried on the first day, when the highest production of 404.7

The third set completed the 400 stalks of 5,840 kgs in one day and 6 hrs. Moderate increase in production was observed. (Table 6, Figure 17) Table 7.
