US12674648 - Zigzag-shaped protection element and method for its production

A method for the production of a zigzag-shaped protection element formed from multiple individual profiles includes the following steps: providing the individual profiles, welding the individual profiles to form a zigzag-shaped preform of the protection element such as to form at least one weld seam, wherein the individual profiles are welded to each another at an angle of 30° to 120°, inserting the preform into a hot molding tool, molding the preform into the zigzag-shaped protection element in the hot molding tool, and mold hardening of the zigzag-shaped protection element in the hot molding tool.

The patent describes a method for producing a zigzag-shaped protection element by welding multiple individual profiles at specific angles and then molding the preform in a hot molding tool. This process includes steps of welding, inserting into a molding tool, and hardening to create the final protection element.

Claim 1

1 . A method of producing a zigzag-shaped protection element, the method comprising: welding a plurality of individual profiles to form a zigzag-shaped preform of the zigzag-shaped protection element so as to form at least one weld seam between each pair of adjacent individual profiles among the plurality of individual profiles, wherein the adjacent individual profiles are welded to each another at an angle of 30° to 120°, inserting the zigzag-shaped preform into a hot molding tool, molding the zigzag-shaped preform into the zigzag-shaped protection element in the hot molding tool, and mold hardening of the zigzag-shaped protection element in the hot molding tool. welding a plurality of individual profiles to form a zigzag-shaped preform of the zigzag-shaped protection element so as to form at least one weld seam between each pair of adjacent individual profiles among the plurality of individual profiles, wherein the adjacent individual profiles are welded to each another at an angle of 30° to 120°, inserting the zigzag-shaped preform into a hot molding tool, molding the zigzag-shaped preform into the zigzag-shaped protection element in the hot molding tool, and mold hardening of the zigzag-shaped protection element in the hot molding tool.
