Toothed rack for guiding and moving a winning machine

摘要

The individual sections 8a of a toothed rack 8 serving to guide and move a winning machine are held together by the connecting member 1 bridging a joint 11 of the conveyor troughs or side spill plates and directly adjacent to the toothed rack 8. This connecting member 1 is provided with an element 10 which limits the clearance of motion of the trough sections or side-spill-plate sections 9 to the tolerance of the pitch size of the tooth system of the toothed rack in order to eliminate inadmissible deviations of the toothed-rack pitch at the joints 11 of the individual toothed-rack sections 8a. <IMAGE>
