CYLINDRICAL VEGETATION BED, METHOD AND APPARATUS FOR PRODUCING THE SAME

摘要

Rod-shaped incipient plant carrying devices which contain or can contain seeds or plant cuttings are formed from a web of paper and a filler of synthetic fibers which are first accumulated into a relatively thin but wide layer which is thereupon converted into a narrow stream. The stream is condensed and simultaneously draped into the web to form therewith a continuous rod which is severed by a cutoff to yield a file of discrete carrying devices of unit length or multiple unit length. Particles of fertilizer can be admixed to the fibers of the stream, and spaced-apart portions of the stream can receive seeds in such distribution that the seed in the finished carrying device is equidistant from both end faces of the filler. A bonding agent can be sprayed onto the layer to ensure adherence of neighboring fibers to one another. The filler can consist of mineral fibers, cellulosic fibers, wood fibers or a mixture of such fibers.
