Abstract
Articles having a defined geometric shape are transported from a starting to an end location by fluid flowing through a pipe system. The articles also flow through at least one jet pump which is creating the flow. Guides for the articles are provided in the pipe and within the jet pump. The articles may be subjected to heat or pressure treatment during transport. To create a predetermined pressure in a particular pipe section, a second jet pump can be positioned at the end of the section and operates in the direction opposing the action of the pump at the starting end.
