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 and/or particles of synthetic foam 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 carring devices of unit length or multiple unit length. Particles of fertilizer can be admixed to the fibers and/or foam particles 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 and/or foam particles to one another. The filler can consist of mineral fibers, cellulosic fibers, wood fibers, a mixture of such fibers, phenol-formaldehyde foam, urea formaldehyde foam, polystyrene foam, polyurethane foam, a mixture of such foams or a mixture of foam and fibers.
