Abstract: A core puller device for a block machine, a block machine with such a device as well as a method for the preparation of shaped stones in which at least one core puller arranged on the sliding facility of the core puller device is temporarily inserted into a stone mould of the block machine and retracted after a packing operation in the block machine are provided. Here, the core puller device is constructed or the method is configured such that the operative connection between the at least one core puller and the sliding facility of the core puller device is temporarily neutralized.

Abstract: A device for transporting and shaking blanks supported on pallets has a shaking station with a shaking table, a feeding conveyor upstream of the shaking station in a transport direction of the blanks, and a discharge conveyor downstream of the shaking station in the transport direction of the blanks. The feeding and discharge conveyors each have a liftable and lowerable transport frame and a drive. The transport frames are movable back and forth by the drive for transporting the pallets. The drives are adjustable to an identical intermittent transport distance and an intermittent transport distance in a ratio of 2:1. On the transport frame of the discharge conveyor a support is provided in an area adjacent to the shaking station. The support raises the discharge conveyor's receiving surface for the pallets and has a receiving surface aligned approximately with a table top of the shaking table.

Abstract: An apparatus for highly controlled color composition and distribution within the face mix of semi-dry concrete mix paving stones.
