  • Page 144 4. Check that a check mark is placed in [Feedrate enable] in Leonardo before clicking [+]. When continuously feeding the belt, you can adjust the feeding speed using the volume in the electric box. 5. Dry the belt. Set the scale of the volume in the electric box to 5, and then rotate the belt in the forward direction for 30 minutes. 6.
  • Page 145 8. Stop rotation of the completely affixed belt and overlap the tape seams by about 5 to 10 mm. 9. Slowly rotate the belt again while checking there is no foreign material adhering to the belt and remove any that is found.

Align the holes on each end of the blade with the supports on the blade installation parts, and slowly and evenly lower the blade on both right and left sides to avoid damaging the belt. 13. Rotate the belt a little in the forward direction and stop. This operation sets the blade at a slight angle against the belt.
  • Page 147 14. Place one glue application block on each end of the belt so that they are aligned with the edge of the blade. When placing the blocks, do not place them on the seams of the insulating tape applied to both sides of the belt. If the seams of the insulating tape come where you want to place the blocks, feed the belt to where there are no seams.
  • Page 148 15. Affix the glue application blocks to both ends of the blade using insulating tape so that there are no gaps in the following: - Between the block and the belt - Between the block and the blade CAUTION Do not affix the blocks in the states described below. There is a risk that the glue may not be applied evenly, or the glue may leak from the belt edge into the machine, causing a malfunction.
  • Page 149 6.2.2 Glue Preparation 1. Prepare the glue for the first layer. Set the glue bucket on the scale and pour in the glue (ATR1945 (ML/T), 1.6 kg). CAUTION When using the glue, wear the personal protective equipment for organic solvent use, such as protective gloves, eye protection, and respiratory protection.
  • Page 150 6.2.3 Glue Application (1st Layer) 1. Rotate the belt in the forward direction. Set the scale of the volume in the electric box at 4 to 6, and then rotate the belt in the forward direction. 2. Apply the 1st-layer glue. Pour a proper amount of glue to right next to the blade. Pour so that the glue flows from the center to both edges.
  • Page 151 6.2.4 Glue Application (2nd Layer) 1. Maintain the belt rotation speed as it is, and when the 1st-layer glue has nearly all been used, pour the 2nd-layer glue. Pour the 2nd-layer glue before the 1st-layer glue has all been used. It is not necessary to pour all of the glue at once.
  • Page 152 2. After it has been completely poured, prepare the soapy water, and gradually pour the soapy water above the belt before locations where the 2nd-layer glue has nearly all been used. The soapy water creates a water repellent membrane on the belt surface so that the glue and blade can be easily separated.
  • Page 153 3. Check that the glue accumulated in front of the blade has been completely used and soapy water is completely applied.
  • Page 154 6.2.5 Blade Removal 1. Two persons are required to lift the blade evenly on both right and left sides, and remove it. Be careful that the blade does not contact the belt surface when removing it. 2. Wipe the blade, glue application blocks, and glue buckets clean using ethanol. If the dirt cannot be removed, soak a wipe cloth in glue remover to wipe off any glue.
