Abstract
A spinner adapted to produce a dual glass fibre component insulation product; said spinner including a plurality of horizontal baffles adjacent to a spinner peripheral wall; said baffles separating two molten glasses of differing coefficients of thermal expansion and providing mechanical strength and resistance to reduce deformation of said spinner.
Claims20
A spinner for use in producing a bi-component fibre containing fibreglass insulation product including an interior slinger cup;
- said slinger cup being circumferentially secured in a fixed manner to a bottom of said spinner inwardly of said spinner periphery;
- said slinger cup having a bottom portion extending inwardly and being adapted to receive a first molten glass A which, through centrifugal movement, forces said glass A in an outward direction;
- said slinger cup further comprising a vertically extending circumferential wall and an upper horizontally extending flange adapted to receive a second stream of molten glass B with a different coefficient of thermal expansion than said first glass A;
- said glass B being forced outwardly through centrifugal movement;
- said spinner having a plurality of vertical baffles creating vertical chambers inwardly of a spinner peripheral wall;
- said slinger cup having a plurality of openings on an outwardly facing wall, such that glass A emerges into first of said vertical chambers and glass B emerges above said slinger cup horizontal flange into second alternative vertical chambers;
- said chambers being greater than 2 in number and lesser than or equal to 32;
- said spinner further comprising a plurality of horizontal baffles disposed between said vertical chambers such that glass A and glass B enter separately from said vertical chambers between said baffles;
- said baffles creating alternate vertically disposed horizontal chambers;
- said spinner on its inner periphery wall having a plurality of apertures adapted to receive glass A from one horizontal chamber and glass B from an alternative upper or lower horizontal chamber;
- said apertures opening into either glass A or glass B channels leading to the exterior peripheral wall whereupon in operation each one of glass A channels and each of one of glass B channels connects to a single common orifice through the spinner exterior peripheral wall;
- said spinner wall having a large number of said single common orifices placed in an ordered fashion, thereby creating a bi-component primary glass fibre, which after further attenuation by a combined action of rotating spinner, external main burner and compressed air blower create curly, irregularly shaped glass fibers.
A spinner adapted to produce a dual component fibreglass product;
- said spinner including a peripheral wall with a dense, staggered and uniform hole pattern.
A spinner adapted to produce a dual component fibreglass insulation product;
- said spinner including a plurality of horizontal baffles adjacent to a spinner peripheral wall;
- said baffles separating two molten glasses of differing coefficients of thermal expansion and providing mechanical strength and resistance to reduce deformation of said spinner.
