The appts. for mixing and delivery of a self-hardening two-component moulding mass, such as for sealing joints and for insulating foams, is a twin-piston mixing gun. The cartridges (11, 11b) have separate cartridge sleeves (22) with a closing plate (23) and a piston unit (24). The holding shaft (4) has a cartridge housing (5) which holds the cartridge sleeves (22) in a flush pressure fit. A dual adaptor headpiece (16) is between the static mixer (6) and the cartridge sleeves (22) in the holder shaft (4) with separate channels open to the cartridges, for material flows, coming together directly at the entry to the static mixer (6). The inner surfaces of the cartridge sleeves (22) are laminated with a film, resistant to the separate components of the two-component mass, using parchment, aluminium or polypropylene. |
