1. A belt for transmitting power or transporting materials on the top side of the assembly comprising:
- an interlocking link belt comprising a series of belt links arranged in superimposed successive overlapping relation, said belt having a thickness between its top and bottom sides corresponding to the thickness of at least two belt links, each of said belt links having;
a body portion with a lateral width, a longitudinal length, at least one aperture, and an integral fastener at the leading end of said body portion and longitudinally-aligned with said aperture, said fastener comprising;
a laterally constricted fastener neck portion; and
a fastening tab connected to said body portion through said neck portion;
said belt links of said series being secured together in overlapping relation to form a belt by the neck of said fastener extending from one of said sides of the belt through said aperture in the preceding belt link, said fastening tab engaging the other of said sides of said belt at the preceding belt link to secure the belt links together; and
a resilient deformable gripping layer comprising a unitary element connected to the belt and overlying substantially the entire length of the top surface of the link belt.

Abstract
A belt for conveying elements in provided wherein the belt comprises a compressible layer attached to the top surface of the belt. Preferably the compressible layer is resiliently deformable to cushion the impact of items on the belt. The belt preferably is a link belt and the top surface of the belt comprises a bonding layer for adhering the compressible element to the belt. The bonding layer may be a thermoplastic urethane that is heat fusible with the compressible layer to adhere the compressible layer to the belt.

4. A method for producing a belt for transmitting power or transporting materials on the top side of the assembly comprising the steps of:
-
providing belt material having a top surface forming a bonding surface;
providing a gripping layer;
placing the gripping layer onto the bonding surface so that the gripping layer overlies the bonding surface;
bonding the gripping layer to the bonding surface, so that the gripping layer is substantially permanently attached to the belt material; and
connecting the ends of the belt material to form a continuous belt. - View Dependent Claims (5, 6, 7, 8)

9. A belt, comprising:
-
a continuous belt comprising a top surface;
a bonding layer adhered to the top surface of the belt; and
a compressible layer adhered to the belt by the bonding layer, wherein the compressible layer comprises an elongated hollow element overlapping the top surface of the belt and having sidewalls extending upwardly from the surface of the belt and a top layer extending between the sidewalls, wherein the top layer of the compressible layer is resiliently deformable. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

36. A method for producing a belt, comprising the steps of:
-
forming a belt having a top layer of heat fusible material;
forming a top element having an outer configuration, wherein the top element comprises a bottom surface formed of heat fusible material; and
adhering the bottom surface of the top element to the top layer of the belt so that the outer configuration projects outwardly from the belt, wherein the step of adhering comprises heat fusing the top element and the belt. - View Dependent Claims (37, 38, 39)
