The stationary head feeder employs a dispersing head with spiked rollers for breaking apart the module. The modules are transported to the stationary dispersing head on a series of beds: each bed is the length of a module and is constructed of flat wire-mesh belts or of chains similar to those of the module truck live bed. A minimum of 1-1/2 beds is required, but additional beds can be added to increase ginning time. The beds can be loaded directly from the module truck once the bed speed and the module truck bed speed are synchronized. After all of the beds are loaded with modules, the ginner selects a bed speed to feed cotton to the dispersing head at a constant rate. When the end bed is emptied, another module can be loaded onto the bed so that ginning is continuous. The modules must be placed end to end to prevent the last part of a module from falling apart as it enters the dispersing head. The stationary dispersing head is equipped with a series of horizontal spiked cylinders that remove cotton from the face of the module and deposit the cotton onto a conveyor or into an air line for mechanical or pneumatic conveying to the gin.

The advantages of module feeding are as follows:
  1. It increases ginning capacity by 10-25 percent by providing a consistent, uninterrupted flow of cotton to the gin plant.

  2. It eliminates suction telescope labor.

  3. It frees the module truck for long hauls by enabling continuous ginning of two to six modules.

  4. It blends wet cotton in the module with dry cotton.

  5. It extracts trash thereby not only reducing the amount of trash entering the gin but also increasing fan and piping life.
