Abstract
Abstract The invention relates to angular guidance for conveyor belt systems, to the outer edge of which conveyor belt a longitudinal bead is attached which is guided between rollers. The axes of the rollers make an angle with one another in a manner that the bead is compressed to produce self-checking and a great amount of friction.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
221 words
An annular guidance apparatus for a conveyor belt supported on a conveyor belt frame wherein the belt runs in a plane defined by the direction of conveyance and including a plurality of conically-shaped idler rollers for leading a conveyor belt around an angular bend of the conveyor belt frame between the idle rollers comprising: a longitudinally extending flexible shoulder member attached to the outer edge of the conveyor belt said shoulder member comprising a plurality of blocks having at least two inner abutment faces disposed on the inner side of said blocks and arranged in a row and evenly spaced over the length of the conveyor belt, said blocks each having an outwardly extending stud member, and a recess for receiving a stud member, each of the recesses of said blocks receiving the stud member of an adjacent block for linking the blocks in series with each other, a plurality of guide rollers mounted on the conveyor belt frame and disposed symmetrically about the conveyor belt at an angle to each other with the axis thereof diverging radially outwardly towards the outer edge of the conveyor belt, said guide rollers engaging the inner abutment faces of said blocks and compressing said blocks between the idler rollers as the conveyor belt is led around an angular bend of the conveyor belt frame.

Claim 3
Dependent Claim
44 words
The angular guidance apparatus as recited in claim 1 wherein each of said blocks includes a convex bearing surface disposed in one side thereof, and disposed on the inner side of the conveyor belt for engaging the idler rollers of the conveyor belt system.
