Reeti tapahie tohu ana ki te qty o te rahi o te karaihe e hiahiatia ana i muri i te tapahi karaihe i mua i te whakakorikori.
Ko te tauira he karaehe whaimana me te rahi e hiahiatia ana qty x te roa o te karaihe e hiahiatia ana x te whanui karaihe e hiahiatia ana / te roa o te pepa karaihe mata / te whanui o te pepa karaihe mata = te tapahi tere
Na i te tuatahi, me tino marama tatou ki te rahi o te pepa karaihe mata me te maha mirimita (mm.) me waiho mo te roa me te whanui o te karaihe ina tapahi:
| Matotoru Karaehe (mm) | Rahi Rau Karaehe Raw Paerewa (mm) | Me waiho mirimita mo te karaihe L. & W. (mm) |
| 0.25 | 1000×1200 | 0.1-0.3 |
| 0.4 | 1000×1500 | 0.1-0.3 |
| 0.55/0.7/1.1 | 1244.6×1092.2 | 0.1-0.3 |
| 1.0/1.1 | 1500×1900 | 0.1-0.5 |
| runga ake i te 2.0 | 1830×2440 | 0.5-1.0 |
| 3.0 & runga ake i te 3.0 | 1830×2400;2440×3660 | 0.5-1.0 |
Hei tauira:
| Rahi karaihe e hiahiatia ana | 454x131x4mm |
| Paerewa Raw Rau Karaehe Rahi | 1836x2440mm;2440x3660mm |
| Me waiho mirimita mo te karaihe L. & W. (mm) | 0.5mm mo ia taha |
| Rahi Rau Karaehe Raw | 1830 | 2440 | 1830 | 2440 |
| Rahi karaihe e hiahiatia ana me te taapiri mm i te wa e tapahi ana | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Te maha i muri i te pepa mata kua wehea e te rahi o te karaihe e hiahiatia ana | 4.02 | 18.48 | 13.86 | 5.36 |
| Tapeke karaehe tohu qty | 4×18=72pcs | 13×5=65pcs | ||
| Reeti tapahi | 72x454x131/1830/2440=95% | 65x454x131/1830/2440=80% | ||
| Rahi Rau Karaehe Raw | 2240 | 3360 | 2240 | 3360 |
| Rahi karaihe e hiahiatia ana me te taapiri mm i te wa e tapahi ana | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Te maha i muri i te pepa mata kua wehea e te rahi o te karaihe e hiahiatia ana | 4.92 | 25.45 | 16.97 | 7.38 |
| Tapeke karaehe tohu qty | 4×25=100pcs | 16×7=112pcs | ||
| Reeti tapahi | 100x454x131/2440/3660=66% | 112x454x131/2440/3660=75% | ||
No reira kua mohio matou, ko te pepa mata 1830x2440mm te whiriwhiri tuatahi ina tapahi.
Kua whai whakaaro koe me pehea te tatau i te reiti tapahi?
