    • The invention relates to a method for the production of shaped foam bodies, comprising: provision of a composition having foam particles and binder; introduction of the composition into a space which is bounded on at least one side by a pressing surface; and exertion of pressure onto the composition by means of the pressing surface. The method further comprises irradiation of microwaves through the pressing surface into the composition, while pressure is being exerted onto the composition. The invention furthermore relates to a device for carrying out the method according to the invention, having: at least one pressing surface and a counterbearing surface lying opposite, between which a space extends which is adapted to receive a composition of foam particles and binder. The pressing surface and counterbearing surface adjoin the space directly. The device further comprises at least one stiff layer which locally or entirely is essentially transparent for microwaves and has a surface facing toward the space, which is connected to the pressing surface in such a way as to transmit force. The device also comprises a microwave radiator unit which is arranged on a side of the stiff layer remote from the space and is aligned relative to the space in order to irradiate microwaves into the space through the stiff layer. Lastly, the invention relates to a microwave radiator unit for the heat treatment of foam compositions. The microwave radiator unit comprises a multiplicity of microwave antennas which are arranged in a plane array and at least two of which are connected through a distributor device to a common microwave signal source, which feeds the at least two antennas.
    • 本发明涉及一种生产成形泡沫体的方法,包括:提供具有泡沫颗粒和粘合剂的组合物; 将组合物引入通过按压表面限定在至少一个侧面上的空间中; 并通过按压表面对组合物施加压力。 该方法还包括将微波通过压制表面照射到组合物中,同时施加在组合物上的压力。 本发明还涉及一种用于执行根据本发明的方法的装置,其具有:相对的至少一个按压表面和相反的表面,在该空间之间延伸出一个适于接收泡沫颗粒和粘结剂组合物的空间。 按压表面和相反的表面直接邻接空间。 该装置还包括至少一个刚性层,其局部地或全部地对于微波是基本上透明的,并且具有面向空间的表面,其以传递力的方式连接到按压表面。 该装置还包括微波辐射器单元,该微波辐射器单元布置在刚性层的远离空间的一侧并且相对于空间对准,以便通过刚性层将微波照射到空间中。 最后,本发明涉及用于热处理泡沫组合物的微波辐射器单元。 微波辐射器单元包括布置在平面阵列中的多个微波天线,并且其中至少两个微波天线通过分配器设备连接到馈送至少两个天线的公共微波信号源。
