Block roughening assembly and method |
摘要 |
A concrete block produced from a workpiece that includes at least a portion of a top surface that is roughened by a roughening assembly. The roughening assembly may include a shaft having a plurality of roughening members, the shaft being rotated in a direction opposed to the movement of the workpiece. A splitting mechanism is provided downstream of the roughening assembly to split the workpiece into one or more blocks. The blocks may be placed in a wall having a setback, with the roughened top surface of each block enhancing a natural appearance of the ledge created as a result of the setback.
