Abstract
703,574. Pneumatic conveyers. WEST POINT MANUFACTURING CO. Sept. 3, 1951 [Sept. 19, 1950], No. 20738/51. Class 78 (1) [Also in Groups VIII and IX] In apparatus for forming a fibrous. web (see Group IX), fibres are removed from the surface of a carding cylinder 12 by a high velocity air stream which enters a duct 14 tangentially to the cylinder through an inlet 28 the width of which js differentially variable over the width thereof by means of a flexible gate 30. A limited amount of air also enters duct 14 through an auxiliary air inlet 38. The fibres are carried by the air stream along duct 14 and deposited on a moving endless flexible screen 16, and are removed by the screen as a fibrous web 122. The air stream passes through screen 16 into an exhaust duct 88 having an elongated throat 90 and a converging section 92 communicating with a duct 96 leading to an exhaust fan. A series of flexible leaf plates 98, each adjustable by a screw 100, is arranged across the width of throat 90 so that the opening at the throat can be differentially varied across the width thereof. Specification 659,088, [Group VIII], is referred to.
