Abstract
A conveyor belt having a plurality of spaced tractive rods including opposing inner and outer ends, and a support surface transversely disposed with respect to a direction of travel and interconnecting the plurality of spaced tractive rods, wherein at least one of the inner and outer ends of at least some of the plurality of spaced tractive rods includes a cone shaped end portion.
Claims15
A conveyor belt comprising:
- a plurality of spaced tractive rods including opposing inner and outer ends;
- and
- a support surface transversely disposed with respect to a direction of travel and interconnecting said plurality of spaced tractive rods;
- wherein at least one of the inner and outer ends of at least some of the plurality of spaced tractive rods includes a cone shaped end portion;
- and
- wherein the cone shaped end portion comprises a frustoconical body portion extending a predetermined length, the cone shaped end portion including tapered side surfaces, a distal end of the tapered side surfaces defining a first width, rounded distal edges, and a substantially planar terminal end surface defining a second width, the second width being less than the first width.

- a plurality of spaced tractive rods including opposing inner and outer ends;
- and
- a support surface transversely disposed with respect to a direction of travel and interconnecting said plurality of spaced tractive rods;
- wherein at least one of the inner and outer ends of at least some of the plurality of spaced tractive rods includes a cone shaped end portion;
- and
- wherein the cone shaped end portion comprises a frustoconical body portion extending a predetermined length, the cone shaped end portion including tapered side surfaces defining a first length between approximately 0.18 inch and 0.25 inch and a rounded terminal end defining a second length of approximately 0.16 inch.

A conveyor system comprising:
- a conveyor belt comprising a plurality of spaced tractive rods including opposing inner and outer ends;
- and a support surface transversely disposed with respect to a direction of travel and interconnecting said plurality of spaced tractive rods;
- wherein at least the inner end of at least some of the plurality of spaced tractive rods includes a cone shaped end portion;
- and wherein at least the outer end of at least some of the plurality of spaced tractive rods include a hold-down clip;
- drive means having driving surfaces configured to engage said cone shaped end portions in direct driving relationship;
- and
- a rail for supporting said belt for passage through an endless path including a helical portion extending through a plurality of vertically spaced loops with the belt curved laterally in each of said loops, an approach portion leading into a first loop at one end of said helical portion and an exit portion leading away from a last loop at the other end of said helical portion;
- wherein said hold-down clips engage said rail at an outer edge of the conveyor belt to thereby hold an inner edge of the conveyor belt away from the drive means, said rail being configured with a predetermined radius of curvature to gradually bring the belt into engagement with the driving surfaces at the approach portion and out of engagement with the driving surface at the exit portion.
