Method of and apparatus for building, guiding and trimming streams of fibrous material

摘要

Belt conveyors which advance two or more discrete streams of fibrous material past discrete surplus removing equalizing devices are guided in such a way that the portions of streams which are in the process of being trimmed are spaced apart from each other stream. This renders it possible to employ reliable equalizing devices having pairs of coplanar rotary trimming discs. The conveyors are guided by pulleys and/or their marginal portions extend into grooves which are provided in the sidewalls of channels for the streams of fibrous material. The equalizing devices are staggered with respect to each other in the direction of transport of the streams.
