Abstract
Compression and bundling forest fuels into suitable units is an alternative to chipping. Bundling can be expected to be associated with considerably better storage possibilities, due to more thorough drying and lowered risk for microbial decomposition. To test the potential of bundling, as well as to explore the handling and storage characteristics of bundles, a test rig - ``Long Bundler`` - was developed which produces bundles with a length of 3 meters and a diameter of 30-40 cm. The bundling process was designed as an almost continuous flow of material through the machine, from feeding of raw material, through compression and binding, to cross-cutting of the finished bundle. The report describes the development of a test rig, time studies of bundling with manual feeding in clearing stands, studies of transport with a conventional timber truck as well as storage and burning of bundles. The produced bundles had an average weight of almost 110 kg which corresponds to 0.114 m{sup 3} (solid) biomass per bundle. The percentage of solid volume was calculated to 37.7 per cent. With one person manoevring the machine and another dragging and loading the clearing wood (diameter 3-5 cm), a performance of 10-12 bundles per work-hour was
