Abstract
A belt for a conveyor system generally includes a ribbon of elastomeric material and a plurality of reinforcing cords connected to the ribbon. The ribbon defines a central longitudinal axis and a pair of side edges extending parallel to the longitudinal axis. At least some of the cords have ends positioned between the longitudinal axis and a side edge.
Claims26
A belt for a conveyor system, the belt comprising:
- a ribbon of elastomeric material defining a central longitudinal axis and a pair of side edges extending parallel to the longitudinal axis, the central longitudinal axis defining a direction of travel of the belt along the conveyor system;
- a first layer of reinforcing cords connected to the ribbon and extending lengthwise between the pair of side edges;
- a second layer of reinforcing cords connected to the ribbon and extending lengthwise between the pair of side edges;
- a third layer of reinforcing cords connected to the ribbon and extending lengthwise between the pair of side edges;
- and
- a fourth layer of reinforcing cords connected to the ribbon and extending lengthwise between the pair of side edges;
- wherein ends of the cords in each of the first, second, third, and fourth layers are positioned between the longitudinal axis and one of the side edges, and wherein the ends of the cords in at least one of a group consisting of the first, second, third, and fourth layers extend in a serrated pattern along a direction parallel to the longitudinal axis when viewed in a direction perpendicular to the longitudinal axis and perpendicular to an axis extending between the pair of side edges.

- a ribbon of elastomeric material defining a central longitudinal axis and a pair of side edges extending parallel to the longitudinal axis, the central longitudinal axis defining a direction of travel of the belt along the conveyor system;
- and
- a pair of reinforcing-cord layers connected to the ribbon, each of the layer including a plurality of cords extending lengthwise between the pair of side edges;
- wherein the cords in one of the layers are angled at an acute angle relative to a direction that is perpendicular to the longitudinal axis, and wherein the ends of the cords in at least one of the layers extend along a direction parallel to the longitudinal axis in a serrated pattern when viewed in a direction perpendicular to the longitudinal axis and perpendicular to an axis extending between the two side edges.

- a ribbon of elastomeric material defining a central longitudinal axis and a pair of side edges extending parallel to the longitudinal axis the central longitudinal axis defining a direction of travel of the belt along the conveyor system;
- a first pair of reinforcing-cord layers connected to the ribbon, the first pair including a top layer and a bottom layer;
- and
- a second pair of reinforcing-cord layers, the second pair connected to the ribbon and including a top layer and a bottom layer, each of the top and bottom layers of the first and second pairs including a plurality of cords extending lengthwise between the pair of side edges, the cords having ends disposed between the central longitudinal axis and one of the side edges;
- wherein the top and bottom layers of the first and second pairs are alternated such that the top layer of the second pair is disposed below the top layer of the first pair, the bottom layer of the first pair is disposed below the top layer of the second pair, and the bottom layer of the second pair is disposed below the bottom layer of the first pair, and wherein the ends of the top and bottom layers of the first pair are recessed relative to the ends of the top and bottom layers of the second pair along a direction that extends between the pair of side edges and is perpendicular to the longitudinal axis.
