Abstract

A connector for connecting modular conveyor links to form a belt includes a rod-like core and a powder coating forming a protective shell. The core may be stainless steel and the powder coating may be nylon.

Claims

1-26. -26. (canceled)

27. A conveyor belt comprising:

a plurality of links arranged in interdigitated rows; and

an elongated connector for connecting the links, the connector comprising a core and a powder coating forming an outer shell on the core.

28. The conveyor belt of claim 27, wherein the core comprises metal, and the shell and links comprise a polymer.

29. The conveyor belt of claim 27, wherein the core comprises metal, the shell comprises nylon, and links comprise acetal.

41. The conveyor belt of claim 29, wherein the core comprises stainless steel.

42. The conveyor belt of claim 27, wherein the outer shell substantially covers the entirety of the connector without a gap between the outer shell and the connector in which food particles or debris may become trapped.

43. The conveyor belt of claim 27, whereby the outer shell lies at least partially between the core and the links.

44. The conveyor belt of claim 27, wherein the powder coating comprises a germicidal, anti-microbial, anti-bacterial, or anti-fungal agent.

45. The conveyor belt of claim 27, wherein the powder coating comprises titanium oxide.

46. The conveyor belt of claim 27, wherein the outer shell is translucent.

30-40. -40. (canceled)

47. A conveyor belt comprising:

a plurality of links arranged in interdigitated rows;

an elongated connector for connecting the links, said connector comprising a core and an outer surface; and

a powder coating applied to the outer surface of the connector forming an outer shell for frictionally engaging a surface of the links.

48. The conveyor belt of claim 47, wherein the outer shell substantially covers the entirety of the connector without a gap between the outer shell and the connector in which food particles or debris may become trapped.

49. The conveyor belt of claim 47, wherein the core comprises stainless steel.

50. The conveyor belt of claim 47, wherein the powder coating comprises a germicidal, anti-microbial, anti-bacterial, or anti-fungal agent.

51. The conveyor belt of claim 47, wherein the powder coating comprises titanium oxide.

52. The conveyor belt of claim 47, wherein the outer shell is translucent.

53. The conveyor belt of claim 47, wherein the links comprise acetal and the shell comprises nylon.

54. A method of using a connector for connecting a plurality of interdigitated links to form a conveyor belt comprising:

providing a connector comprising an electrically conductive material;

coating an outer surface of the connector with a powder coating to form an outer shell on the connector; and

connecting the interdigitated links with the coated connector.

55. The method of claim 54, wherein the providing step comprises spraying nylon in powder form to the outer surface of the connector and heating the powder to cure the powder into form the outer shell.

56. The method according to claim 54, wherein the coating step further comprises forming the outer shell without a gap between the outer shell and the connector in which food particles or debris may become trapped.
