Abstract: The invention relates to a quick set-up system for calibration devices located downstream from an extruder, in particular one for synthetic profiles. With this quick set-up system, a dry gauge and the vacuum tank(s) are mounted on two horizontally positioned tubes that are positively connected to the calibration stage, such that they can be moved and adjusted horizontally and vertically, which enables an exact advance adjustment of the gliding device, and with it, of the vacuum tanks and calibration device, thus eliminating a subsequent alignment. In addition, by installing a central water disposal system, the required replacement of hoses with different lengths when moving the vacuum tanks is avoided.

Abstract: The device is a section connector for building structures, such as, for instance, a rafter assembly section connector for winter gardens or the like, with the aid of which a hollow section can be attached to another hollow or solid section at variable angles. An inset equipped with a ball head is firmly attached to one section. Using the ball head, the inset is connected to a structural part attached to another section in such a way that it can pivot.

Abstract: A window or a door has a frame structure and a U-shaped bar simultaneously serving as reinforcement section and a turn-tilt mechanism.

Abstract: The apparatus includes a hollow chamber, preferably made from a synthetic material, such as PVC or other plastic, with an insertable reinforcement piece suitable for connecting to window, door or other configurations, such as abutment and frame profiles. The reinforcement piece comprises a unitary rolled sheet metal with one or more screw channels within the reinforcement profile for a front face abutment screw connection. The reinforcement piece further includes at least one shank inwardly extending from the screw channel toward the opposite chamber wall. The reinforcement piece further includes a shank extending around the inner walls of the hollow chamber.
