PURPOSE:To obtain a conveyer suitable for conveyance in a steep slope, by forming a part of prescribed area in an upper side material of a main unit belt at a prescribed distance, separating or cutting to raise said part of prescribed area and forming a cross frame. CONSTITUTION:Cross frames 6 are formed on the upper surface of a belt main unit 2 of a conveyer belt by separating or cutting to raise a part 5 of prescribed area at prescribed distance except a one side 6a. In this constitution, as compared with those as conventionally adhesively with the cross frame 6 to belt main unit 2, the cross frame 6 can increase its strength and is never exfoliated, further labor hours for adhesively attaching the cross frame 6 to the belt main unit 2 can be eliminated. |
