Spade splice

An improved form of the finger splice is the spade splice. The interconnecting ends of the belt join together to form an exceptionally strong splice with no additional thickness.

In thick materials it is possible to make this splice without a reinforcing strip, as its strength increases with total cross section of the bond area: (length of bond line) x (thickness of base material).

A number of different reinforcing materials, such as films, fibre reinforced films and PTFE-glass, are used for both simple Butt , Longline and spade splices. Achieving the necessary strength while keeping the splice as thin as possible can be difficult. The type and size of re-inforcing strip is chosen to match the belt fabric, size of belt and intended application.
