Abstract
The problem of wet-cast concrete products getting stuck or being uncontrollably ejected from a flexible mold during demolding is solved by moving the flexible mold through a passage, defined by both a mold-receiving surface and a rotatable mold-support distanced therefrom, while moving an edge of the flexible mold along an unsmooth path that includes at least one sharp point.
Claims7
A method for demolding at least one flexible mold that is at least partially filled with dried wet-cast concrete products and that has a front edge;
- the method comprising:
- providing a table and a mold-support member so distanced from the table as to define a passage for the at least one flexible mold therethrough;
- the mold-support member being rotatable about an axis parallel to the passage to minimize friction in the passage;
- receiving the at least one flexible mold on the table so that the front edge extends out of the passage;
- and
- moving the at least one flexible mold through the passage while moving the front edge along an unsmooth path about the mold-support member.
