Method of packaging flock fibres
Abstract
Flock textile fibres are placed in a collapsible bag having openings that are large enough to permit the escape of air but too small to permit the escape of any significant amount of fibres, the bag is partially covered with a wrapping material, and pressure is applied by a baler or other compressing device, compressing the fibres within the bag and expressing air outwardly through the openings, and strapping or wiring is wrapped around the wrapping material and secured under tension. The wrapping material may be closed at the ends to form an envelope.
