Abstract
A telescoping roller conveyor is disclosed wherein interwoven rollers are provided on axles. The axles are linked to adjacent axles within siderails. The links allow the axle separation to expand a limited distance longitudinally as siderails are telescopically extended. The links are enclosed in channel-shaped telescoping siderails and do not project above the level of the rollers in any position and thus do not provide any obstruction to items moving over the rollers along the conveyor. The axles are seated into special round plastic bushings that aid the movement of the telescoping longitudinal siderails and the relative movement of the axles to and from each other.
