Abstract
The present invention provides a transport or conveyor belt structure, particularly for use in heavy duty environments such as mining, aggregate and ore handling and other industrial conditions, where the belt preferably comprises a carcass that is made from identical cross-shaped interengaging metal links embedded within the body of the belt so as to provide both strength and flexibility. A method of making such a belt comprising building up layers of belt material and links is also described as are unique structures for joining and splicing belt ends or sections.
Claims18
A transport belt comprising:
- a plurality of plies of flexible material adhered together, and
- an interposed carcass comprising a plurality of interengaging links embedded within said flexible material wherein said links each comprise a substantially planar, cross shaped member having a central body and two pairs of opposing arms disposed across said flexible material in an alternating and partially overlapping arrangement with the ends of said arms being disposed perpendicular to the plane of said central body.
A transport belt for a conveyor comprising:
- a first rubber layer having an upper surface and a lower surface,
- a second rubber layer having an upper surface and a lower surface,
- a third rubber layer having an upper surface and a lower surface and disposed between said upper surface of said first rubber layer and said lower surface of said second rubber layer,
- a plurality of link members each comprising a substantially planar cross-shaped member having a central body and two pairs of opposing arms, the ends of said arms being bent so as to be substantially perpendicular to the plane of said central body for a length corresponding substantially to the thickness of said third rubber layer,
- wherein a first layer of said link members is disposed in rows and columns on said upper surface of said first rubber layer with said ends of said arms pointing upward away from said first rubber layer, adjacent link members being spaced apart a distance less than the distance spanned by opposing arms of said link members,
- said third rubber layer is disposed over said first layer of said link members whereby said ends of said arms pierce said third rubber layer and said lower surface of said third rubber layer contacts said upper surface of said first rubber layer between said link members,
- a second layer of said link members is disposed in rows and columns on said upper surface of said third rubber layer with said ends of said arms pointing downward toward said first rubber layer, adjacent link members of said second layer being spaced apart a distance less than the distance spanned by opposing arms of said link members and said link members of said second layer being disposed over spaces between said link members of said first layer whereby said ends of said arms of said second layer pierce said third rubber layer so as to be located parallel to and inward of said ends of said arms of first layer of said link members whereby said third rubber layer is confined between said first layer of said link members and said second layer of said link members, and
- said second rubber layer is disposed over said third rubber layer and said second layer of link members whereby said lower surface of said second rubber layer contacts said second layer of said link member and said upper surface of said third rubber layer between said link members,
- whereby said first, second and third rubber layers are adhered together forming a unitized belt body with said interengaging link members confined therein.
