Abstract
The invention concerns a slip-form casting machine for fabrication of elongated concrete products. The slip-form casting machine comprises a feed hooper (1), an auger (6) for exerting pressure onto a concrete mix to be cast, and a casting mold (10, 11). According to the invention, the casting mold (10, 11) is a tubular construction plugged at one end, and the auger (6) is connected to a casting machine body (18) which is substantially complementary with the cross section of the casting mold (10) and is movable with respect to the mold (10) in order to facilitate slip-form casting of a product (7) with an elongated shape in the axial direction of the casting mold. The slip-form casting machine in accordance with the invention produces smooth and high-quality surfaces in concrete products.
