Рабочая поверхность полого корпуса скалки выполнена в виде, по меньшей мере, восьмигранной призмы, ребра которой сглажены. Во втором варианте рабочая поверхность скалки выполнена в виде упругого спирально закрученного листа с возможностью изменения его диаметра. Внутри упругого спирально закрученного листа расположен подвижный валик, выполненный с возможностью вращения вокруг неподвижной оси, концы которой выполнены в форме загнутых ручек. Жгут теста распределяется вокруг корпуса скалки и сцепляется концами. Валиком внутри корпуса тесто прижимается к столу и обкатывается. Операция повторяется несколько раз и сопровождается раскручиванием листа и распределением теста по его увеличивающейся поверхности. В третьем варианте скалка содержит полый цилиндрический корпус, по торцам которого на осях с возможностью вращения установлены ручки, совмещенные с разделочной доской, которую крепят к поверхности стола. Разделочная доска снабжена направляющими. На осях укреплен механизм регулирования прижима и перемещения полого цилиндрического корпуса скалки по направляющим вдоль разделочной доски.
