Where should belt marriage start?

Belt marriage, also known as the process of aligning and joining multiple sections of a belt, should start at the termination point. This is important because the termination point serves as a reference for ensuring that the belt is properly aligned and secured. Beginning the process here allows for a more accurate and consistent installation, which is crucial for ensuring proper function and longevity of the belt system.

Starting at the termination point ensures that the belt can be properly tensioned and adjusted as it is being joined. It helps to identify any potential issues with alignment or fit before the entire belt is completed. In multi-piece belt systems, this approach facilitates a smooth integration of the sections, reducing the likelihood of operational problems such as slippage or misalignment during use.

The other options represent potential starting points; however, they may not provide the accuracy and reliability needed for a successful belt marriage. The midpoint may lack a clear direction for aligning the belts, while starting at the drive mechanism or tensioning device could lead to difficulties in achieving proper alignment throughout the full length of the belt.
