Abstract:

A phase control system for a fan blade assembly of a folder is provided which includes a fan blade assembly, a folded product transport assembly, and a control system. The fan blade assembly includes a first and second rotating fan blade assembly. The first rotating fan blade assembly has a plurality of first fan blades and has a first circumference. The second rotating fan blade assembly includes a plurality of second fan blades and has a second circumference. A product receiving area is defined at an intersection of the first and second circumferences such that only one of the first and second fan blades can occupy the product receiving area at any instant. The folded product transport assembly is provided for delivering folded products to the product receiving area. The control system includes a first sensor, a second sensor, and a fan blade assembly motor actuator. The first sensor detects an edge each folded product as it passes a first position and outputting a first signal indicative thereof The control system then estimates a first instant at which each folded product will reach a reference position as a function of the output of the first sensor.
