An improved system for changing sipe blade configurations on equipment for the manufacture of tires is provided. This system allows the replacement of damaged sipe blades, the replacement of sipe blades of one configuration with those of another configuration, and the elimination of a sipe blade altogether. Certain embodiments allow sipe blades to be changed by providing a sipe blade that is held by a blade holder with a slit in its heel that allows a compact assembly of the sipe blade and blade holder that is easy to manufacture. Other embodiments allow sipe blades that have an undercut in the direction of draw in, their midportion and side portions without undercuts to be easily made and installed. Finally, other embodiments allow for the effective replacement and fabrication of sipe blades that have undercuts in the direction of draw that blend into other projections found on a curing member.
