Abstract

1,229,431. Lap forming apparatus. OWENSCORNING FIBERGLAS CORP. 25 June, 1968 [25 July, 1967], No. 30296/68. Heading D1N. [Also in Division G3] In a system in which a glass fibre mat is made by depositing fibres from a heated fibreproducing bushing on to a conveyor, the speed of the conveyor is automatically varied in dependence on the amount of heat supplied to maintain the bushing at a desired temperature so as to produce a mat having a desired weight per unit area. In Fig. 1, molten glass is supplied from a furnace 10 to an electrically heated bushing 11 from which it issues through. orifices 12 and is formed into fibres by gas or steam jets at 13. The fibres fall within a hood 30 having adjustable side walls, and binder or other material such as oil is added through dispensers such as 50. The mixture forms a mass on a conveyor belt 41 to which it is held by suction. The mat is then transported by a series of conveyors past a compression device 66, an electric heater 74, an edge trimmer 80 to a cropper 85 which cuts it into lengths for packaging. A master controller, which may be operated manually or from a tape reader, sets hood width, binder feed rate, conveyor speed, oven conditions, trimmer position and cropping time to values which are automatically maintained by closed loop control systems. The power supplied to the heater of bushing 11 is automatically controlled to maintain a desired temperature and variations of this power, being representative of changes in the rate of fibre production, are applied to vary the datum of the systems controlling binder feed rate, conveyor speed, oven conditions and cropping. An X- ray gauge 60, responsive to mat density also automatically modifies these controls in dependence on variations of mat density or operates an alarm if the variations exceed a predetermined magnitude. Additional correspondence control linkages are also provided between certain of the controls.
