Double groove interlocking tile
The double recess interlocking tile is a further development of the interlocking tile . It has a double groove on one side and two ribs on the other. Due to the development of the pressed roof tile , its production increased in precision. This storm-proof roof tile is used in almost all regions of Germany.
prehistory
An interlocking tile with a simple groove was patented by the Gilardoni brothers from Altkirch as early as 1841. Because the patent protection lasted only ten years at the time, many brickworks copied this so-called heart tile from 1850, and the Gilardonis patented a tile with a double groove ( tuile à double emboîtement ) on March 21, 1851 , which was awarded at the Paris World Exhibition in 1855 .
Pressed roof tiles
Pressed roof tiles are pressed with the help of punches , usually revolver presses , between an upper and a lower mold pressed roof tiles. Such pressed roof tile models with head and side seams were developed in 1881 by Wilhelm Ludowici , the technical director of Ludowici Ziegelwerke on the basis of the heart tile as Z1 and helped the company to achieve an economic breakthrough.
