    • Apparatus for forming melt-formed fibres comprises:- • a source of molten material; • a spinning head comprising one or more rotors; • a plurality of nozzles or slots disposed around at least part of the one or more rotors, configured to supply a stream of gas; • a conveyor; and • a barrier (4) between the spinning head and the conveyor (6), an upper edge of the barrier lying below a horizontal line (22) lying in a first vertical plane (17) including the axis of rotation (16) of at least one rotor of the one or more rotors and intersecting the intersection of the axis of rotation with a second vertical plane (18) orthogonal to the first vertical plane and including a vertical line (20) through said region, the included angle between the horizontal line (22) and a line (21) in the first vertical plane joining the upper edge of the barrier and the intersection of the horizontal line and axis of rotation being in the range 40°-85°. Method of making melt-formed fibres using the apparatus. Melt formed biosoluble fibres being alkaline earth silicate fibres having a low shot content.
