Abstract
A method and installation for feeding longitudinal elements of round or flat material to a welding machine (41) for grates or gratings, in which method the longitudinal elements (L), cut off from at least one line of longitudinal-element material after straightening of the same, are arranged in a group with selectable spacing, without longitudinal displacement, in the direction transverse to a push-in line (S) to the welding machine (41), are secured in place by a, for example magnetic, holding force and are moved essentially continuously into the push-in line, and in which arrangement the front ends of the longitudinal elements are mutually aligned before delivery of the longitudinal elements to the welding machine.
