Abstract
Abstract Core conveyor means of the endless type moving synchronously or non-synchronously with one or more continuous casting devices is disposed in side-by-side relation with the continuous casting device or devices, and the conveyor means is moved in the same direction as the molds moving in the continuous casting device or devices. The cores supplied from a core supply source which may be a core making machine, a group of core making machines consisting of two or more core making machines or a core cage stack hose with stacker crane are fed through the agency of the core conveyor means to the continuous casting device or devices. By this arrangement, it is possible to supply cores quickly or smoothly or supply large numbers of cores of different types with a high degree of efficiency to the casting device or devices.
