Abstract
A novel seal, weighing tube and filling tube for a weighing feed system spout advantageously used for simultaneously filling and weighing bags with particulate material. The seal is an annularly shaped non-resilient member installed between the exit ends of the tubes to prevent accumulation of particulate material which would otherwise adversely affect the accuracy of the weight measurement. The seal is made of a non-influencing material such as dacron, silk, cotton or the like to preclude weight measurement inaccuracy. The weighing and filling tubes are provided with unique seal retainer rings which provide for retention of the seal by means of an effective gathering such as a drawstring on the filling tube and an O-ring on the weighing tube. An optional tool is disclosed for facilitating seal installation.
