Disclosed herein is an invention having to do with a method and apparatus for supporting and tensioning cleaning blades that are in contact with a moving conveyor belt. The method and apparatus disclosed herein comprise locating an elongate support bar under the return side of a conveyor belt and positioning its length transverse to the direction of travel of the conveyor belt. The support bar has mounted spatially along its length several individual spring loaded piston-cylinder assemblies. Support plates are connected to the extensible end of each piston-cylinder assembly and cleaner blades are removably attached to the support plates. Each piston/cylinder assembly has an adjustable spring tensioning adjustment for the proper tensioning of each blade. The cleaner blades and piston-cylinder assemblies are arranged adjacently with one another along the length of the support bar, and the blade assemblies have side edges preferably with tongue and groove connections so that each adjacent cleaning blade has a sliding engagement with one another. On each end of the transverse support bar is located a pneumatic/hydraulic, extension/retraction mechanism that connects between the transverse support bar and a support bracket for firmly anchoring the scraper blade assembly to a foundation.

The invention is a method of joining two belt ends together, either laterally or longitudinally, and the resulting belt. The two ends can be of two different belts being joined, a short section added to replace a damaged section of a belt, or two ends of the same belt. Moreover, the belt or belts can be damaged or intentionally cut in preparation of their joining. The belt ends are stripped of their rubber or elastomeric coating that covers the cord core, and the ends can be fashioned in any shape such that one belt end complements the other end when abutted. The ends are joined and a new rubber layer is then bonded to the belt above and below the cord core.

The invention is a method of splicing two damaged ends of a conveyor belt together such that the resultant spliced belt is stronger than typical splice methods. The damaged belt is cut apart and the ends are prepared so that the ends may be spliced together. The belt ends are stripped of the rubber coating that covers the cord core through cutting or abrading the coating away. The belt ends can be prepared in any fashion from blunt end cuts to stepping the cut of the core such that the steps of one end of the belt complement the steps of the other end of the belt. The prepared belt ends are mated together and sewn. A new layer of rubber is then placed over the sewn portion of the belt. The new layer of rubber is then vulcanized, through either hot or cold vulcanization techniques. The resultant sewn and vulcanized belt is a stronger belt than a belt repaired by only mechanical or vulcanization methods.

The present invention describes a tensioner that automatically increases the effective torque on the support arm over time. The tensioner is comprised of a torsion cam engaging the support arm of the scraper blade assembly, a torsion cable engaging the cam, a tension rod with a spring surrounding the rod secured to the torsion cable. Over time, as the scraper blade wears down and the spring force decreases, the torsion cam is slowly rotated to increase the torque arm of the invention and thereby increase the effective torque on the support arm and compensate for the decrease in spring force. This invention may be adapted for use with any existing scraper blade assembly.
