Abstract: A drawing unit including two or more slits extending in a widthwise direction of a collecting conveyor, each slit including an inlet for sucking groups of filaments pushed out from a spinneret, a path in which air currents flowing in a suction direction is formed for drawing the groups of filaments, and an outlet for blowing out the groups of filaments towards the collecting conveyor after the drawing. The drawing unit and a drawing method are capable of producing a non-woven fabric web with uniform thickness and with only a small number of density spots as a result of reduced entanglement of the filaments in the paths of the drawing unit.

Abstract: A fiber spinning device and process for manufacturing a web of fibers including a homogeneous mixture of fibers of different characteristics. Monocomponent fibers of different polymers can be extruded side-by-side from the same die system. Sheath/core bicomponent fibers can be alternated with monocomponent fibers formed of the same core polymer as used in the bicomponent fibers. Bicomponent fibers having a common core polymer and different sheath polymers can be extruded from alternate spinneret orifices in the same die plate. Multiple distribution plates are provided with surface grooves or depressions to direct polymer materials from independent sources to only selected spinneret openings in an array of spinneret openings while maintaining the polymers segregated from each other. Unique products formed from the improved mixed fiber technology are useful as high efficiency filters in various environments, coalescent filters, reservoirs for marking and writing instruments, wicks and other elements designed to hold and transfer liquids for medical and other applications, heat and moisture exchangers and other diverse fibrous matrices.

Abstract: An apparatus for melt blowing thermoplastic fibers especially suited for recycled plastic where molten polymer is extruded through a die head into an array of removable nozzles, each nozzle having a shoulder back end in contact with the die head, and discharged into ambient air while surrounded by a high velocity, high volume discharge of hot air wherein the nozzles are inserted through an array of nozzle holes in the back end of a strand plate bolted to the die head, and pass through an air chamber defined by the interior of the strand plate, air is heated to high temperatures with a direct flame and channeled to the air chamber, the outside face of the back end of the strand plate includes recessed areas corresponding to each nozzle hole, for receiving the shoulder back end of each nozzle, each of the nozzles can be serviced and replaced simply by releasing the strand plate and withdrawing one or more nozzles therefrom, a desired spatial configuration of and proper alignment of the nozzles is maintained with alignment strands placed between the rows and columns of nozzles such that the alignment strands and nozzles are in tangential contact, a cover plate with orifices corresponding to and concentric with each of the removable nozzles and having an inner diameter larger than the outer diameter of the nozzles can be placed over the array of nozzles and alignment strands such that the nozzles extend through the concentric orifices forming an annulus around the nozzles for uniform discharge of high velocity, high volume hot air around the discharged molten polymer.
