A material feeder is provided that includes a drum having a number of compartments that receive material that is to be output by the feeder. The material can be any one of many different materials that are usually light and/or smaller in size, such as insulation, powders, grains and the like. At least a first seal is provided adjacent to the drum to close off an end of each compartment during some of its rotation. The first seal is preferably stationary during rotation of the drum and its compartments. The position of the seal relative to the drum can be adjusted to provide desired positioning between the seal and the drum. In one embodiment, the first seal is in contact with at least portions of the first end of the drum. The material is delivered to each compartment in the drum preferably using first and second fillers that are mounted adjacent to and outwardly of first and second ends of the drum.
