Abstract: A tool for placing and securing sealing strip (11) into a joint gap (19) between structural parts (17, 18) includes a lead-in device (10) guiding the sealing strip (11) into the joint gap (19), an insertion device (8) aligning the sealing strip (11) and a contact pressure device (7) with two coextensive contact pressure faces (12, 13) for pressing the sealing strip (11) within the joint gap (19). A spacing (A) between the contact pressure faces (12, 13) transversely of their coextension is variable.

Abstract: Member for mixing and dispensing a two-component mass from a tool arranged to separately squeeze-out the two components. The member includes a mixing tube (1) enclosing a coaxial tube section (2) connected to the front end (3) of the tool for conveying one of the components from a tool outlet (3b) to the mixing tube (1). Another tool outlet (3a) conveys the other component directly into the mixing tube (1). The tube section (2) has a one-way valve at an outlet opening (2b) into the mixing tube (1). The one-way valve includes an expandable tubular sheath (5) covering the outlet opening (2b) through the tube section (2). The one-way valve prevents any backflow of the mixed components from the mixing tube into the tube section. Mixed components which harden within the mixing tube (1) form a seal or block. Accordingly, when the tool squeezing out the component is operated with a blocked or sealed mixing tube, no backflow into the tool can occur.
