Abstract

The invention concerns the production of homogeneous and structurally resistant sheets or mats of thermoplastic fibers, such as glass fibers, issuing from one or more spinnerettes above a travelling conveyor. The fibers are deposited on the conveyor after being blown through a stationary skirt or conduit formed essentially of a pair of large plane surfaces having critically controlled spacings therebetween to attain predetermined cross-sectional areas between the inlet and outlet end of the conduit, as well as adjustable outlines of the outlet. These variable and/or adjustable sectional areas serve to control the pattern and area of deposition of the fibers on the conveyor. A plurality of spinnerettes and guide conduits may be arranged in different patterns and alignments relative to the direction of travel of the conveyor to control the laying-up of the fibers and consequently the physical characteristics of the deposited mat. Additional trapezoidally shaped shaping members, also each formed essentially of a pair of large plane surfaces with an inlet and outlet, as well as intermediate sections of predetermined or adjustable areas, may be used in lieu of or in conjunction with the above-mentioned skirts or conduits. These shaping members are fitted with openings and/or blowers for air or gaseous currents to afford a convenient control of the entrainment of the dropping fibers passing therethrough, which discharge from the outlet ends of said members, which are spaced a slight distance above the travelling conveyor.
