Abstract
An industrial belt having a non-linear seam adapted to be on-machine joinable. In a particular embodiment, the seam is made up of a opposite end regions of the belt having complementary projections, such as in the form of castellations, which engage at the seam, providing a completely integrated belt throughout the zone of the seam. In the field of papermaking, the belt of the invention can take the form of a transfer belt, whereby the invention provides a fully interlocking, strong seam which minimizes any potential mechanical or hydraulic sheet marking. The invention also includes a method of creating the end regions of the belt, seaming the belt, and casting the belt.
