Straps are used to form a supporting plane for a body resting on a supporting structure, which straps are double folded and inserted under the body while holding one end of the strap until the other end of the strap is completely inserted under the body. Two bars are placed parallel and with a certain distance from the body on each side of the body. The free part of each strap is attached, double folded, to one of the bars. The attachment point of the strap is rotated around the geometric axis of the bar in such a way that the part of the strap, which runs from the body, will be placed over the double folded end. The end of the strap, which has been inserted under the body is fixed on the other bar or is attached in the same way as the first end. |
