The escalator step (1) or the travelator plate comprises a step skeleton (2) 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.

La présente invention concerne une marche d'escalier mécanique (1) ou une palette de tapis roulant composée d'une structure de marche (2) ou d'une structure de palette qui porte au moins un élément de marche (22). Un premier limon (3), un limon central (4), un second limon (5), un support (6), un pont (7) et une console (8) forment la structure de marche (2). Pour chaque limon (3, 4, 5) une découpe de tôle est découpée dans une bande de tôle, puis est façonnée sous forme de limon au moyen d'un procédé d'emboutissage. Les supports (6), les ponts (7) et les consoles (8) relient les limons (3, 4, 5). Les composants sont soudés au moyen d'un procédé de soudage par points. Les supports (6), les ponts (7) et les consoles (8) sont fabriqués en continu à partir d'une bobine de tôle au moyen d'un procédé de roulage et sont coupés à longueur selon la largeur de marche.
