An extruder haul-off has an upper track unit pneumatically pressed towards a lower track unit to grip the extrudate. The upper unit comprises a cross-piece(20) connecting two side straps(18,19), each carrying two rollers(5,6;7,8) at a vertical distance from each other. The rollers(5,6;7,8) are guided by a vertical double guide formed by two special profiles(3,4), each with two inner side guide faces(11) and an inner base guide(12).
