Method for producing flat roof tiles - involves producing outer convolutions to height corresponding to twice normal height and has tool on press device producing notches on tiles

摘要

The outer convolutions in a form corresp. to the suspension nose formations are produced with a height corresp. to double their normal height. Directly at the outlet of the mouthpiece of the extrusion press device (7) a notching tool (10) produces notches along the connecting lines of the tiles. Before or at the same time as the cross-cutting of the round edges of the tile in the unnotched area striker blade (14,17) is applied centrally in the longitudinal direction and in the area of the inner end of the suspension nose formations crossways over the total width. ADVANTAGE - To produce flat roofing tiles with low energy input in continuous operation and directly in an endless run.
