A composition and process of preparation of emulsifier agents based on an alkylpolyglycoside structure with a length of alkyl chain having from 6 to 12 carbon atoms to be used. Aspects of the invention relate to the use of the vaccines of the invention for the treatment andor prevention of human and animal disorders. The gripping pressure regulator regulates the gripping pressure. A burner opening for inserting a burner is formed in the burner insert wall. The compressive stress renders the fibers or the fiber containing material more rigid, stronger and more resistant against bending force, impact or tensile force.
