This invention relates to a molded crawler track comprising metallic core bars set in an endless rubber belt. The core bars comprise first and second wings (2, 4) extending in a transverse direction to the axis of the track and, between the wings, a sprocket part (3) which is engaged by a drive spro

This invention relates to a molded crawler track comprising metallic core bars set in an endless rubber belt. The core bars comprise first and second wings (2, 4) extending in a transverse direction to the axis of the track and, between the wings, a sprocket part (3) which is engaged by a drive sprocket. A protrusion (5, 15) is provided on either side of the sprocket part, i.e. protruding out of the plane of the wings towards the guide wheel for the track. The protrusions serve to guide the track over the guide wheels. The protrusions are inclined; one forward, one towards the rear; The relative dimensions of the elements of the core bars, are given. This combination of features reduces the occurrence of fatigue fractures and cracks in the belt.

The magazine of claim 5, wherein the force exerted on each of the bristle bundles is greater than 3 pounds. 7. The magazine of claim 6, wherein the force exerted on each of the bristle bundles is greater than 5 pounds. 8. The magazine of claim 7, wherein the force exerted on each of the bristle bundles is greater than 8 pounds. 9. The magazine of claim 8, wherein the force exerted on each of the bristle bundles is greater than 12 pounds. 10. The magazine of claim 9, wherein the force exerted on each of the bristle bundles is greater than 18 pounds. 11. An improved magazine for transporting bristle bundles having a backplate, a mold plate, a locking plate disposed between the mold plate and the backplate, a plurality of channels traversing the magazine, each channel comprising collinear first, second, and third holes in each of the backplate, locking plate, and mold plate, respectively, and a sliding cam action slidably disposed within the locking plate, wherein the locking plate retains the bristle bundles in the channels when the sliding cam action is in a first position and releases the bristle bundles when the sliding cam action is in a second position, wherein the improvement comprises that the size of each of the second holes is adapted and constructed such that the locking plate exerts a consistent force across each bristle bundle when the sliding cam action is in the first position.
