1. 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.
