Abstract: In an apparatus for producing foamed plastics parts, a closed mold (1) is filled with polymer molding compound and, after the elapse of a reaction time, the finished part is removed. A plurality of identical molds (1) run on mold carriers (5) through a production installation. For the purpose of reducing the production outlay, a demolding device (11) shared by all the molds (1) is brought into operative connection successively with the molds (1) and in each case one mold (1) is opened. The movements required in this operation are executed by the demolding device (11). An unlocking unit (19) and a swiveling unit (20) of the demolding device (11) are brought into engagement with the mold (1) by a positioning unit (21), after which the mold (1) is unlocked and one mold half (1a) of the mold (1) is swung open. For unlocking the mold (1), the latter is raised against spring force and a positive locking is brought out of engagement.

Abstract: An improved latex composition is provided that has been found to exhibit a superior ability to form a substantially uniform polymeric film when applied to a substrate. The composition is capable of being handled and applied to a substrate in the absence of excessive foaming. The aqueous composition includes as essential components specified concentrations of a specifically-defined normally liquid predominantly hydrophobic nonionic ethylene oxide/propylene oxide block copolymer surfactant, and a solely hydrophobic defoaming agent (e. g., a hydrocarbon-based mineral oil). It is possible for the composition to be applied even to a hydrophobic substrate (e.g., a polyester film substrate). Compositions of the present invention, following application to a substrate and the volatilization of the water component, form a substantially uniform polymeric film that can serve as a coating or adhesive.
