Abstract

The specification discloses a strike off apparatus for levelling and compacting mounds of sand (32) extending above the upper edges of open-top mold boxes (22) of varying heights carried in succession along a pathway. A pair of pivotally supported rollers (38A, 38B) extend across the pathway. A sensor (36) determines the height of a sand mound in a mold box before it reaches the rollers. An elevating mechanism including a hydraulic cylinder (110) responsive to the sensor adjusts the rollers to a height so that they level and compact the sand mound as the mold box is carried thereunder. A control system including electrical and hydraulic circuits is provided for automatically controlling the cyclical operation of the apparatus.
