Abstract: A system for producing plastic containers with a heating device for heating plastic preforms, wherein the heating device has a transport device for transporting plastic preforms along a predetermined first transport path, and a plurality of holding devices for holding the plastic preforms and at least one heating device which heats the plastic preforms during the transport thereof and comprising a forming device for forming the plastic preforms to form plastic containers. The forming device is configured for expanding the plastic preforms heated by the heating device by applying a flowable medium, and includes a plurality of forming stations which form the plastic preforms to form the plastic containers. Both the heating device and the forming device have changeable elements, wherein the system has a changing device configured for changing both changeable elements of the heating device and changeable elements of the forming device.

Abstract: A sailing or wave-riding board includes a foam core, a support layer, and a cover layer. The board has a number of incisions at least in portions of the surface of the support layer. The incisions increase the bending capacity of the support layer so that it can also be adapted to the contour in more curved areas of the foam core, in particular in a boundary area.
