<p>The invention relates to a moulder that has a machine table (9) on which the workpieces (1) lie that are to be machined, and a truing table (2) on which the workpieces (1) are fed to said moulder. The moulder has horizontal and vertical spindles on which there are machining tools that machine the four sides of the workpiece (1) as it passes through the moulder. In order to avoid workpieces being wasted as a result of incorrectly-adjusted machine elements, or at least to keep such wastage to a minimum, the moulder is provided with at least two lasers (18, 20, 23, 24) the laser beams (19, 21, 26, 27) of which are directed towards the workpiece (1) situated on the truing table (2), producing straight lines on said workpiece (1). These indicate the amount of chip removal to be carried out on the workpiece (1) using the machining tools (5 to 7, 10), and therefore the workpiece dimensions and/or geometry to result from the subsequent machining. The one laser (18, 23) is coupled to, and can be adjusted with, one of the spindles, while another laser (20, 24) is arranged to be fixed in place. The laser beam (22, 27) thereof characterises the zero line of a stop (28) or the zero line of the machine table (9) as a straight line on the workpiece (1). The stop (28) forms a stop edge or a stop plane for the workpiece (1) as it is conveyed through the moulder. In this manner, the problem of workpieces being wasted as a result of incorrectly-adjusted machine elements can, at least, be kept to a minimum.</p> |
