A STRUCTURAL COMPONENT AND A METHOD AND MACHINE FOR ITS MANUFACTURE

摘要

A method for manufacturing an elongated, box-like structural component comprising two mutually opposing side-members (1, 2) which define a cavity therebetween. The mutually opposing surfaces of the side-members present longitudinally extending grooves into which projections on distance pieces (3) located between the members engage. In the process of manufacturing the structural component pairs of boards or the like are advanced in spaced relationship in the longitudinal direction of the boards into a receiving station (7) with the grooved inner surfaces of the boards facing one another, the distance pieces (3) being placed between the boards as they enter the station (7). As the boards leave the station, they are pressed towards one another in a manner to bring the projections on the distance pieces (3) into engagement with the grooves on the inwardly facing surfaces of the boards. The invention also relates to a machine for use when carrying out the method, and to a structural component manufactured in accordance with the method.
