Abstract

A molding device includes at least two component form boards 12, 13 and a wedge-shaped spacer board 14 between them. An operating means is associated with the form boards and the spacer, and moves them relative to one another. The operating means 25 includes at least one rack member 18, and at least one lever 26 connected with a pawl 28 which swings about an axis eccentric with the axis of the lever. The pawl 28 engages with the rack 18 and moves the rack forward when the lever is operated.
