This parameter only applies to a Twinpress XL270.

Each Forming Press has a lower forming tool that provides back pressure as the press forms each tile step. The XL is reponsible for raising this tool once the formed step is out of the way. There has only ever been one parameter since each press, including the lower forming tool has always been identical. On some parts, where the last step of the part was too close to the first step of the next part, the lower forming tool for press 1 would not raise.

One machine builder has designed a notch into the lower forming tool of Press 1 that now allows the lower forming tool to raise under the conditions described above. A new setup parameter, called Forming Tool 1 Notch Width, is intended to describe the width of the notched area so that the XL can now calculate when it is safe to raise the tool. The setup defaults to zero.
