driving the pressure tool and the molding tool to form the
backing in the shaping zone and conveying the backing in a
transport direction; and
molding the moldable material in mold cavities in the molding
tool, each of the mold cavities having boundary walls opposite one
another extending in a lengthwise direction of the mold cavity
continuously along a convex path, each convex path having a
curvature in a form of a hyperboloid with a more pronounced portion
defined by decreased radii of curvature and by narrowing of spaces
between the boundary walls, each more pronounced portion being
closer to a head molding part of the cavity than to a base molding part
of the cavity, each cavity being rotationally symmetrical to form
rotationally symmetrical interlocking structures.
