Section 2: Overview
2-11
The starting point for a string is the String Spool and Tension Lever Assembly. From the spool the
string routes through the String Wagon. The wagon moves back and forth in the main frame to lower
or raise the pins. From the wagon, the string continues through the Pin Motion Interface (PMI). The
PMI contains a switch that detects when a pin has been knocked over and a string brake that controls
whether the pin will be lowered to the pindeck when the string wagon moves toward the front of
the machine. Finally the string routes through a centering cone before it is tied to the pin. Refer to
Figure 2-11 .
