PURPOSE: To combine, composite and cover arbitrary raw materials in simple operation by discharging an outer cover raw material from an outer cover feeder having good quantification to a compositing nozzle, intermittently feeding a inner raw material from a though type inner raw material feeder having a piston hole crossing to the axis of cylinder at right angle in a proper amount and further feeding the outer cover raw material to cover the inner raw material with the outer raw material.

CONSTITUTION: An inner raw material feeder E is a though type feeder in which both ends of a piston hole crossing at right angle to axis of cylinder are opened outside the cylinder. Rotation of the cylinder is carried out by an eccentric shaft machine. Receiving and extruding of the raw materials is carried out by mutually changing opening of both ends of piston hole in turn by reciprocation of piston. An outer cover raw material C is discharged from an outer cover raw material feeder A to the tip of compositing nozzle port by control of a valve B. Then the inner raw material F is packed in proper amount by intermittently operating the inner raw material feeder and further the outer cover raw material C is fed to cover the inner raw material with the outer raw material.
