Transportsystem

The guide rail (1) comes in U- or C-shape in a spatial co-ordinate system having a central flange (5) equidistant from the end flanges (2,3) and equipped both sides with pressurised sleeves (13,14) and associated drive rollers whose axes lie in the assumed connection between the tracking rollers (11,12) or that between the outer tracking rollers. The rail is symmetric to the plane of the centre flange and the legs (4) linking the two outermost leg flanges (2,3) are grooved on the side away from the flange lengthways so as to fix the rail to the underframe. Prism or vee-shaped strips (6,7) fitted to the outside of the rail end flanges (2,3) in the upper parts of the rail edges facing away from the leg (4) serve as guides for the transport carriage and the rail has two lengthways adjusting holes (8,9) for centring pins, notably holes on the inside of the end flanges and at the top free edge of the centre flange. The holes slide to one side to enable the pins to be clipped into place. The centre flange also has vertically offset latching grooves where it faces the end flanges, standing open to accept latching webs (13a,14a) fitted to the respective sleeves (13,14).
