Abstract
The invention relates to the production of mineral fibers from a material melted in a cupola. To regularize the supply of material to the fiber-forming apparatus, the material emanating from the cupola and conveyed to the apparatus passes through a reserve.
Claims15
A method of continuously supplying fiber forming mineral material in a fiber producing apparatus, comprising the steps of:
- delivering fiber forming mineral material in liquid form and at an elevated temperature from a cupola to a reserve means having a free surface;
- discharging said material at said free surface to a first wheel of a fiber producing apparatus including centrifuging wheels rotating in opposite directions;
- and
- permitting said material to flow to others of said centrifuging wheels while forming filaments, wherein said delivering step includes the step of delivering said material to said reserve means with a volume sufficient that said material is homogenized therein and with said free surface of an area such that a flow rate of said discharging step does not exceed 2% of a mean flow rate thereof, regardless of momentary variations in a flow rate of said delivering step.

An apparatus for continuously supplying fiber forming mineral material in a fiber producing apparatus having a plurality of oppositely rotating centrifuging wheels, comprising:
- material reserve means having sufficient volume that said material is homogenized therein and having a free surface;
- means for delivering said material in liquid form and at elevated temperature from a source thereof to said reserve means;
- and
- means for discharging said material at said free surface from said reserve means to a first wheel of said fiber producing apparatus,
- wherein said reserve is constructed such that said free surface has an area such that a flow rate of said material from said discharging means does not exceed 2% of a mean flow rate thereof, regardless of momentary variations in a flow rate from said means for delivering.
