By the way, when manufacturing conveyor belts,
It is common practice to join the ends of a belt body manufactured in a straight line (band shape) to form an endless belt, and use this by mounting it.For example, as a means for joining belts into an endless shape, As shown in FIG. 2A, the end surfaces of the belt ends B1 and 5B1 that are butted against each other are cut out in a tapered shape, and these surfaces are joined with adhesive C, or
As shown in the opening of Figure 2, the end faces of the belt ends B1 and Bl are cut out in steps, and these are combined and joined via adhesive C, but both are the joint parts! 0 extends to some extent along the running direction of the belt, which impairs the flexibility of this part and makes it weaker than other parts, making it more prone to peeling, breakage, etc. Was.

The reason why monofilament is used as the axial fiber when weaving the woven fabric cylinder 10 is that when the belt is cut in the final process, these fibers become the constituent fibers in the width direction of the belt, and during use of the belt. This is to prevent the belt from warping, to provide rigidity in the width direction of the belt, and to provide so-called stiffness to prevent cargo from spilling while the belt is in use.

Also, the reason for alternately arranging S-twist and Z-twist fibers in the circumferential direction fibers is that when only either S-twist or Z-twist fibers are used, a biased force is applied to the belt in one direction, causing the belt to This is because the straightness of the belt may be hindered, so by alternately arranging S and Z-twisted fibers, the bias can be canceled out and the straightness of the belt can be improved.
