METHOD OF AND DEVICE FOR MAKING GASKETS FROM FOAM USING FLEXIBLE FOAM MIXING CHAMBER Russian patent published in 2002 - IPC

FIELD: production of gaskets. SUBSTANCE: proposed device feeds chemically active components of foam into inner space between two panels of plastic film to form protective gaskets. Device has plastic film feeder and unit to set film in motion, for instance, two flexible rolls. Foam component metering unit is installed between film panels and it injects chemically active components of foam into inner space where they are mixed to form mass of expanding foam. Plastic film forms flexible mixing chamber in zone between two flexible rolls in which chemically active components of foam are mixed after feeding. EFFECT: improved efficiency of device in operation. 5 2 cl, 19 dwg
