A sheetlike semifinished product comprising a matrix having at least one latent reactive plastics composition which is curable to afford an elastomer, in particular a thermoplastic elastomer, and fibers embedded in the matrix. A process for producing sheetlike semifinished products is further disclosed.

A method for producing blocks of windows (). The method comprises the following steps: i) providing a frame consisting of frame profiled elements () having one or more panes () arranged therein, wherein a gap () can be formed between at least one frame profiled element () and the one or more panes (), ii) inserting adaptable, particularly temporary, boundaries () for bounding the application region into the gap (), wherein the application region is bounded by the boundaries () in the peripheral direction, the frame profiled element (), and the one or more panes (), and iii) introducing the curable plastic () into the application region.

A method and an apparatus are described for the production of a mitered corner joint between parts of a frame, by vibration welding. During the welding procedure, in each case two parts of a frame are displaced by oscillatory heads into mutually perpendicular straight-line translatorial oscillations, the phases of which have been matched to one another in such a way that mitered areas of the two parts of the frame oscillate perpendicularly with respect to a stationary mitered plane and through the same, while the mitered area is retained under a prescribed welding pressure in the system. The method and the apparatus can be used for the simultaneous production of the four corner joints of a frame, in particular of a frame of the moveable or fixed part of windows or of doors. For this, at least four, and preferably eight, oscillatory heads, which displace the parts of the frame into the translatorial oscillations, are synchronized in such a way that their frequencies and amplitudes are the same.
