Abstract
A conveyor belt has a mono-ply construction comprising a central fabric ply, top and bottom cover layers and a connection interconnecting the opposite ends of the belt. The top and bottom cover layers are removed from the opposite ends of the belt to define exposed fabric ply regions which are arranged in a mutually overlapping relationship. Two connection plates extend generally over the entire width of the conveyor belt on opposite sides thereof, and fasteners extend through the connection plates and the opposite ends of the conveyor belt to form a secure, yet flexible, connection.
Claims25
A conveyor belt with opposite ends thereof interconnected by a connection assembly, comprising:
- first and second connection plates extending generally over the entire width of said conveyor belt, positioned on top and bottom sides of said conveyor belt, and having oppositely oriented leading and trailing regions with respect to the running direction of said conveyor belt;
- fasteners extending through said first and second connection plates and said opposite ends of said conveyor belt;
- and wherein
- said conveyor belt has a mono-ply construction including a flexible central fabric ply, a top cover layer and a bottom cover layer, with said top and bottom cover layers being completely removed from said conveyor belt at said opposite ends thereof to define recesses in which said first and second connection plates are received, and exposed fabric ply regions which are arranged in a mutually overlapping relationship, and permit said conveyor belt to readily flex at both said leading and said trailing regions of said first and second connection plates to reduce wear and noise as said conveyor belt passes over pulleys.

A method for making a conveyor belt, comprising:
- forming a conveyor belt with a mono-ply construction having a flexible central fabric ply, a top cover layer and a bottom cover layer;
- removing completely the entire top and bottom cover layers from the opposite ends of the conveyor belt to define recesses therein, and exposed fabric ply regions;
- arranging the exposed fabric ply regions on the opposite ends of the conveyor belt in a mutually overlapping relationship;
- positioning first and second connection plates having leading and trailing regions with respect to the running direction of the conveyor belt in the recesses on the top and bottom sides of the conveyor belt to extend generally over the entire width thereof;
- and
- inserting fasteners through the first and second connection plates and the opposite ends of the conveyor belt to create a secure connection which permits the conveyor belt to readily flex at both the leading and trailing regions of the first and second connection plates to reduce wear and noise as the conveyor belt passes over pulleys.
