Abstract

A conveyor belt system includes a splice rod having a j-shaped hook on each end thereof and a plurality of links for receiving the splice rod therethrough. The links further include a specially modified link end for securing the rods.

Claims

1. A conveyor belt comprising:

a plurality of spaced tractive rods;

a plurality of rows of flat wire wickets transversely disposed with respect to a direction of travel and interconnecting said plurality of spaced tractive rods,

wherein at least one of said rows of flat wire wickets includes an outer edge link on each end thereof, said outer edge link including a projecting tab on an outer side thereof; and

wherein at least one of said plurality of rods includes a hooked shaped end on each end thereof, at least one hooked shaped end of said at least one rod engaging the projecting tab on one said outer edge link.

2. The conveyor belt according to claim 1, wherein in said at least one of said rows of flat wire wickets, each of said links defining sad at least one row includes a pair of projecting legs, said legs including an opening sufficiently dimensioned for passage of said hooked shaped of said rod.

3. The conveyor belt according to claim 2, wherein said hooked shaped ends on said rod engage the projecting tab on each said outer edge link on said row.

4. The conveyor belt according to claim 2, wherein said at least one rod comprises a first edge rod, a center splice rod, and a second edge rod.

5. The conveyor belt according to claim 4, wherein said first edge rod and said second edge rod include hooked shaped ends on each end thereof and said center splice rod includes hooked shaped ends on each end thereof.

6. The conveyor belt according to claim 5, wherein one of said ends of said first edge rod engages said projection tab on one of said outer edge links, one of said ends of said second edge rod engages said projection tab on another of said outer edge links, the other end of said first edge rod and the other end of said second edge rod engaging opposing hooked shaped ends of said center splice rod.

7. The conveyor belt according to claim 1, wherein said at least one of said rows of flat wire wickets comprises said plurality of rows of flat wire wickets.

8. A conveyor belt for conveying product in a direction of travel, said conveyor belt comprising:

a plurality of pivotal transverse rods extending laterally across the belt, said transverse rods having inner and outer ends along inner and outer edges of the belt, said inner and outer ends of said transverse rod having a hooked configuration;

a plurality of connecting links arranged in at least one longitudinal row along the inner and outer edges of the belt and pivotally interconnecting the inner and outer ends of the transverse rods, respectively, each of said connecting links having a pair of longitudinally extending legs and an opening extending laterally through each said leg such that said hooked configuration of the transverse rods extend through said openings, wherein an outer leg of each said connecting link includes an extension having an opening therein;

wherein said hooked configuration of said inner and outer ends of said transverse rod are disposed through said openings in said outers legs of said connecting links.

9. The conveyor belt according to claim 8, wherein at least one of said plurality of transverse rods includes a first edge rod, a center splice rod, and a second edge rod.

10. The conveyor belt according to claim 9, wherein said first edge rod includes a hooked configuration on each end, said center splice rod includes a hooked configuration on each end, and said second edge rod includes a hooked configuration on each end.

11. A method of manufacturing a conveyor belt, said method comprising:

providing a plurality of transverse rods including a hooked shaped end on each end thereof;

providing a plurality of wickets or links having a first pair of openings extending laterally therethrough and a second pair of openings extending therethrough, said outermost edge wickets or links including a projecting extension;

arranging the transverse rods through the first and second pair of openings so as to pivotally interconnect the transverse rods in a longitudinally spaced arrangement; and

wherein said hooked shaped ends of said rods engage the projecting extensions on said outermost wickets or links.

12. The method according to claim 11, wherein said projecting extension on said outermost edge wickets include projecting tabs, said hooked shaped ends of said rods engaging the projecting tabs.

13. The method according to claim 11, wherein said projecting extensions on said outermost edge links include extended link legs having an opening therethrough, said hooked shaped ends of said rods extending through said openings.

14. The method according to claim 11, wherein said rods include a first edge rod, a center splice rod, and a second edge rod, said method further comprising arranging said first edge rod from an intermediate belt position to an outer edge position, arranging said second edge rod from an intermediate belt position to an outer edge position, and joining said first and second edge rods to said center splice rod.
