Abstract
1526316 Incorporating inserts in foam mouldings DEMAG KUNSTSTOFFTECHNIK ZWEIGNIEDERLASSUNG DER DEMAG AG 20 Feb 1976 [27 Feb 1975] 06834/76 Heading B5A A method of incorporating an insert 2 in a foam moulding 1 of a window frame element comprises supporting the insert 2 on cores 10, introducing the foamable mixture 1 through one or more lines 8 and withdrawing one or more cores 10 to be flush with the moulding surface at the point in time when the forming foam can support the insert without a substantial shift in position and yet can still seal the space vacated by the core(s). The point in time can be determined by the pressure of the foam in the mould cavity, or by timers connected to the foam feed metering unit 9. The cores may be withdrawn simultaneously or sequentially, e.g. the upper core 10 may be withdrawn first, at a constant, e.g. 20 mm./sec. or variable rate, may have different sizes, and may be adjustably mounted on respective piston rods 14 via a sleeve 15. Each core 10 may be actuated by an hydraulic piston/cylinder arrangement 11 which may be controlled in a common or specific solenoid valve 17 by timers of the metering unit 9. The insert 2 may be of steel and may be prestressed by the cores 10.
