Abstract
A conveyor belt zipper has complementary connectable halves disposed on each end of the conveyor belt. Those halves have a plurality of teeth and recesses thereon, with the teeth being insertable into the recesses. The teeth are of different sizes, are supported by either a thick or a thin section of the half, or are constructed of either a flexible, or a inflexible material. Also, a reinforcing member can be attached to the halves in order to achieve the desired relative flexibility. In this manner, the zipper has sufficient strength to withstand tension due to a load on the belt, while also having sufficient flexibility to rotate easily around an end roller of the conveyor assembly.
