Method of manufacturing an improved bag for the cultivation of mushroom spawn and apparatus therefor
Patent number: 5662576Abstract: A method and apparatus for manufacturing an improved bag for the cultivation of mushroom spawn is provided. The bags have continuous gas permeable sealing strips sealed to the inside walls of the bags which cover openings in the bag, so as to allow the bag to be vented without loss of moisture. The openings and sealing strips are positioned close to the top and bottom of the bag so as to maximize air flow through the mushroom spawn without creating dry spots, thereby improving spawn yield. The apparatus includes rollers for dispensing plastic film and at least one continuous hydrophobic strip of material. A series of apertures are punched by cutting dies in the film, and a vacuum system removes the cut out portions. The strip of material is positioned over the apertures and sealed by sealing dies over them, so as to enclose the apertures. A cutting dies cuts off the film and strips. A conventional bag making machine then forms the bags.Type: GrantFiled: March 29, 1995Date of Patent: September 2, 1997Assignee: Compac International, Inc.Inventors: Gregory S.
