Claims15
A conveyor comprising:
- a conveyor belt constructed of a plurality of first rows of first belt modules and a plurality of second rows of second belt modules wherein the first rows and the second rows are alternately connected to each other in series at hinge joints between consecutive first and second rows;
- a sprocket having teeth engaging the first rows of first belt modules and not the second rows of second belt modules.
A modular conveyor belt comprising:
- a plurality of first rows of first belt modules and a plurality of second rows of second belt modules wherein the first rows and the second rows are alternately connected to each other at hinge joints between consecutive first and second rows;
- wherein each of the first rows has a drive face for receiving a drive tooth and wherein all the second rows are devoid of drive faces.
A conveyor comprising:
- a conveyor belt constructed of a series of rows of belt modules linked together at hinge joints between consecutive rows, wherein the hinge joints have hinge axes spaced apart in a direction of belt travel by a distance defining the belt pitch;
- a sprocket having teeth engaging every other row of belt modules, wherein the circumferential spacing of the teeth defines the drive pitch;
- and
- wherein the drive pitch is twice the belt pitch.
