There is disclosed a method of forming a joint in a belt having first and second end-edges to be joined. The method involves providing an aramid fibre section, for example as a discrete piece, having first and second edges. The first end-edge of the belt is arranged to overlap the first edge of the fibre section from one side and the second end-edge of the belt is arranged to overlap the second edge of the fibre section from the other side. The first and second end-edges are joined to the fibre section in said arrangement to form a joint interface between the first end-edge and the second end-edge, with the aramid fibre section reinforcing the joint. An adhesive may be used to bond the fibre section to the belt material. A woven aramid fibre section may be used. The fibre section may be located between plies of the belt. A variety of belts with a joint formed by the method are disclosed, including belts with spliced joints or mechanical joints.
A method of forming a joint in a belt having first and second end-edges to be joined, the method comprising:
A method of forming a joint according to any of the previous claims, where the belt comprises a plurality of plies, where the fibre section is inserted or arranged between the plies at the first end-edge of the belt.
A method of forming a joint according to any of the previous claims, where the first and/or second end-edges are profiled to define splice formations.
A method of forming a joint according to any of the preceding claims, where the splice formations of the first end-edge are interposed between opposing splice formations of the second end-edge.
A method of forming a joint according to any of the previous claims where the first end-edge abuts or overlaps with the second end-edge when joined to the body portion.
A method of forming a joint according to any of the previous claims, where the fibre section comprises a fibre body portion which is coated in an adhesive.
A method of forming a joint according to any preceding claim, where the fibre section comprises para-aramid fibres.
A method of forming a joint according to any of the previous claims, where fasteners are joined to the first and second end-edges, preferably hook-fasteners or clips, or staples, the fasteners spanning the joint interface.
A reinforced belt, comprising a belt body and a fibre section, where the fibre section comprises aramid fibres and is joined proximal to a first end edge of the belt body that forms an interface with an opposing second end edge of the belt body such that the belt body defines a closed loop, the fibre section having a discrete length in a longitudinal direction of the belt body such that it terminates on either side of the interface and the belt body extends in the longitudinal direction beyond the fibre section.
A fibre section sheet material for use for in forming a reinforced belt joint, the fibre section having a fibre composite layer comprising a textile having aramid fibres provided in an adhesive matrix;
