segments 140 and 142 are configured to be linear meaning rectilinear and are oriented exactly across the direction of transport of the workpieces 112 this arrangement of the disc grinders 122 ensures that the disc grinders 122 extend uniformly over the entire width of the workpiece independent of the actual width of the individual workpiece moreover it is thus achieved that the disc grinders 122 are caused to move over the workpieces 112 at a uniform speed so that machining of the workpiece surface is perfectly uniform in thus designing the grinding station 114 the surface of the workpiece is optimally ground across the direction of transport and by having the disc grinders 122 rotating about their vertical axis 130 the workpiece 112 is also ground at a great variety of different angles it has thereby been found advantageous to adjust the distance between two neighboring disc grinders 122 as a function of the infeed direction of the workpieces 112 in such a manner that a grinding tool 122 is passed over actually each point of the workpiece surface the entire grinding station is height adjustable by means of a hoist thus being capable of machining workpieces of different sizes fig4 illustrates a second embodiment of a continuous through feed grinding machine of the invention that only differs from the first embodiment.
