摘要

Method for manufacturing a bent curve element and a blank for manufacturing a bent curved metal element for an endless chain conveying track are disclosed. The bent curve element has a support flange intended to constitute a guide rail for a first side of chain elements forming part of the chain conveying track, and a web from which the first flange extends. The web is intended to provide torsional rigidity to the bend element. A bend element is used to make bend unit which in turn is used to make a conveying track.
