Concrete block machine having a controllable cutoff bar |
摘要 |
An automated concrete block machine including a mold cavity, a feedbox driven between retracted and extended positions and depositing concrete in the mold cavity when at the extended position, a cutoff bar, and a drive system coupled to and driving the cutoff bar in a direction of movement of the feedbox such that a distance between at least a portion of the cutoff bar and a top of the mold varies so that the cutoff bar removes varying amounts of concrete deposited in the mold cavity so that a depth of concrete remaining in at least a portion of the mold cavity varies so as to be unevenly distributed in a desired fashion in the direction of movement of the feedbox.
