Abstract:
An in-line method of manufacturing thermoplastic nonwoven components comprising:(a) mounting a spunbond spinning assembly on a first vertically moveable support structure having an upper position and a lower position; (b) positioning the first vertically movable support structure to an upper position wherein the spunbond spinning assembly is positioned above the lower position; (c) positioning a quenching device and filament drawing device under the spunbond spinning assembly in vertical alignment therewith; (d) extruding filaments from the spunbond spinning assembly; (e) passing the filaments through the quenching device and the filament drawing device; (f) depositing the filaments onto a conveyor to form a first layer; (g) mounting a meitblowing spinning assembly on a second vertically moveable support structure; (h) positioning the second vertically movable support structure in a lower position; (i) passing the conveyor with the first layer under the meltblowing spinning assembly; (j) meitblowing filaments from the meltblowing spinning assembly; and (k) depositing the meltblown filaments on top of the first layer.
