Abstract: A device for supplying a gas stream to a tool for molding molded parts made of a fiber-containing material. Steam generated during molding is removed from the molded parts pressed in the tool via channels in the tool. A tool with such a device and a method for controlling the supply of a gas stream into the tool are described.

Abstract: An apparatus and a method for heating process media in a fiber molding process are described, whereby an optimization of the efficiency in the production of three-dimensional molded parts from a fiber-containing material is provided. Here, a process medium with a relatively high temperature is guided through an apparatus for heat exchange within a container with another process medium.

Abstract: A method for temperature control in a molding tool, which has a tool base body and at least one cavity, for producing molded parts from a fiber-containing material and a molding station with at least one molding tool are described.

Abstract: A method for suctioning fibers from a pulp using a suction device with a suction tool, and a suction device for suctioning fibers from a pulp with a suction tool that has a plurality of cavities for suctioning fibers are described.

Abstract: A method for regulating a hot-pressing device, a tool component and a hot-pressing device are described, wherein the closing of the hot-pressing device and the pressing of a first tool component and a second tool component are effected according to a boiling temperature, ascertained in advance, of the liquid contained in a fiber-containing material of at least one preform and a surface temperature of a first molding device of the first tool component.

Abstract: A tool component, a hot-pressing device and a method for hot pressing preforms from a fiber-containing material are described, wherein the hot-pressing device has a first tool component with a first tool body and at least one first molding device and a second tool component with a second tool body and at least one second molding device. The method includes providing at least one preform made of fiber-containing material, heating the first tool body and the first molding device via a temperature control device, placing a preform on first contact surfaces of the first molding device, moving the second tool component relative to the first tool component, and pressing the first tool component and the second tool component until the first contact surfaces and the second contact surfaces form a closed cavity.
