Method for manufacturing panels or profiled workpieces for annual plants

Abstract From the Canadian patent

Raw material for the manufacture of panels or profiled workpieces from annual plants is to be stored less expensively while maintaining the quality of the plant parts resulting during harvest and the further processing conducted with simplified equipment. The plant parts (e.g. from flax straw, hemp, twigs, reed, sugar cane, cotton stalks) are pressed into bales after harvest. The bales are completely wrapped with a liquid-proof vapour-permeable foil. The wrapped bales are stored until processing. The plant parts can be processed further without additional drying.
