A straklatte is an elastic lath made of wood or plastic. It is mainly used in shipbuilding for design, untying and construction. The lengths accordingly range from a few decimeters for slats for the drawing board to over ten meters for lacing and construction. With their help, you can draw harmonious lines without sudden changes in the radius of curvature (i.e. bumps or flat spots) or detect such unwanted places during construction. In the case of wooden slats, it is therefore important to use pure wood with an even grain. Sharpening should be avoided; where this is not possible, they must be made very long.
The laths are held and shaped by straight weights ( pigs ) or nails that are driven in next to the lath.
Today, special computer programs are able to calculate straightening lines so that straightening battens are no longer necessary in the construction. It is also possible to plot the finished line crack on a non-warping film; In this case, there is no need to work on the cord floor either . When building boats and yachts, however, the street bar is still an important tool for checking the course of the lines.
The English name of the Straklatte, " Spline ", has become a term used in geometric modeling .
