Width extension part for modular belt

A width adjustment device used in connection with adjusting the width of conveyor belts of the type made up from a large number of substantially identical belt modules, where each module along leading and trailing edges in the intended travelling direction is provided with eye parts separated by openings, such that an eye part on one module may be fitted in an opening on an adjacent module, and where the eye parts are provided with an aperture laterally, such that when a conveyor belt is assembled from a plurality of belt modules, a connection pin may be inserted laterally through the openings in overlapping eye parts, thereby hingely connecting adjacent belt modules, and where the conveyor belt defines a transport plane, where the width adjustment device has a height orthogonal to the transport plane, and a length in the intended travelling direction such that a device on one module at least partly overlaps with the device arranged on the upstream and/or downstream module, and a width perpendicular to the intended travelling direction, where said device is detachably arranged on each belt module along one or both sides of the conveyor belt.
