Abstract: The subject matter of the present invention is a continuously operating transporting device, in particular for treating foundry cores and molds, with an endlessly revolving conveyor belt and uniformly spaced-apart insertable grippers which are supplied and controlled with air via an annular line with connecting pieces, which is coupled to the conveyor belt, with the insertable grippers cooperating synchronously with a rotating distributor arranged on a drive shaft with spring-mounted connecting pieces. With the aid of the apparatus of the present invention, it is possible to treat or machine individual or interconnected foundry cores and molds in a fully automated and continuous operation in line with the production.
