发明名称 STEP FOR ESCALATOR OR PLATE FOR TRAVELATOR, AND ESCALATOR OR TRAVELATOR AND METHOD FOR PRODUCTION
摘要 The escalator step (1) or the travelator plate comprises a step skeleton or a plate skeleton which carries at least one tread element (22). A first cheek (3), a central cheek (4), a second cheek (5), a carrier (6), a bridge (7) and a bracket (8) form the step skeleton (2). For each cheek (3, 4, 5), a sheet metal blank is stamped from a sheet metal strip and is subsequently formed into the cheek by means of deep drawing processes. The carrier (6), bridge (7) and bracket (8) connect the cheeks (3, 4, 5), wherein the components are welded by means of spot welding processes. The carrier (6), bridge (7) and bracket (8) are produced endlessly from sheet metal coil by means of a rolling deformation process and are cut to length depending on the step width.
