The yokes are adjustable in radial direction with respect to the slipform platform while the form sheets are adjustable in tangential or circumferential direction with respect to each other. One of the form work walls is radially adjustable with respect to the other. The slipforming means is intended for slipforming hollow, inclined columns having increasing and/or decreasing diameter.
