PROBLEM TO BE SOLVED: To provide equipment for producing a nonwoven fabric, capable of much reducing downtime of the equipment, and therefore capable of improving productivity thereof, by making it possible to safely and rapidly conduct an operation in which a rectangular spinning pack extended in the transverse direction of the equipment is exchanged. SOLUTION: In this equipment for producing the nonwoven fabric of synthetic fiber, yarn threads are melt-spun through a rectangular spinneret extended in the transverse direction of the equipment, the spun yarn threads are sucked by a rectangular air-sucker corresponding to the width of the rectangular spinneret, the sucked yarn threads are drawn at a specified draw ratio, and the drawn yarn threads are further sucked to be caught on a collecting conveyor positioned under the spinneret together with air fed to the air-sucker and associated with the yarn threads. Further, the rectangular spinning pack is composed of a rectangular die block for distributing polymer and the rectangular spinneret which is fasten to the die block with bolts, wherein the die blocks is equipped with two or more protrusions each having a polymer inlet port on one of side surfaces parallel to the transverse direction and other protrusions each having a bracket for supporting a thrust rod on the opposite side surface. Thus, the spinning pack is attached to a housing for the spinning block used for heating and keeping the pack warm in such a manner that protrusions of the spinning pack are each attached to grooved parts which are arranged in the in inner surfaces of the housing to be engaged with the protrusions.
