Abstract
A method of automatic packing of comminuted silicon includes providing an inner bag in a first shaping vessel, spreading out an opening of the inner bag and positioning the opening above a lip of a first filling funnel of a filling unit, and filling the inner bag with comminuted silicon. The comminuted silicon passes through the filling funnel into the inner bag. The inner bag is welded in a welding unit. The opening of the inner bag is folded together by inward folding of two opposite inner bag sides such that two inner bag edges formed by the folding-together are opposite and parallel to one another and form a fold with a channel. A vacuum welder is applied to the fold and welds the inner bag. The inner bag is transferred into an outer bag. The outer bag is welded.
