A short 1929 article by W. Mayr describing a pneumatic automatic feeder for willows and cards (opening and carding machinery) in textile preparation, patented by Heinrich Glass of Lambrecht, Germany. It explains how a fan and suction funnel draw raw material onto a moving lattice, with delivery rollers and a fluted roller giving an even, adjustable feed, and notes advantages over spiked-lattice feeders. Two figures show the apparatus in section and elevation, and a closing note covers oiling wool with an automatic spraying device.
