PL102221B1 - METHOD AND APPARATUS FOR PNEUMATICALLY MANUFACTURING YARN - Google Patents

Description

The invention relates to the pneuma process manufacturing yarn and equipment for making yarns of natural and chemical fibers mical.

The pneumatic compartment process is based on introducing the fibers into the non-ribbed chamber to create whirling rings from my rings it under the action of air jets and produced projecting the appropriate field of peripheral speeds in the section where the forming takes place and the twisting of the yarns by collecting the fibers of the tufts ruin ring.

A known device for pneumatic opening constitutes a non-rotating cylindrical chamber into which the fibers are guided and set in motion swirling by means of air streams sucked in to the koimora through the channels -located around the perimeter chambers. The produced front is led out channel located in a cylindrical cartridge ce, located inside the chamber.

The process of overrunning occurs the faster the the peripheral speeds in the area of the mold are greater the ring of the fibers. The right one shaping the field of peripheral speeds the formation of the vortex gene gene in the axis of the chamber followed by others vortex field tensification, preventing increasing ganglion speed near walls chambers. and a method of pneumatic yarn production according to the invention, it is limited the flow of large swirling air particles speeds up to the vortex core and forces it to flow swirled air along the walls of the chamber more.

Machine for making yarn according to the invention, which is a non-rotating cylindrical roller precinct chamber, has an forcing element air flow along the walls of the chamber, located beneath the ring of swirling fibers and / lulb air guides placed below this element in the chamber outlet.

. ^ Forcing air to flow along the wall the leg of the chamber weakens the intensity of the swine flow ditch in the core area, increasing the speed venture. Placement in the chamber outlet the air gap allows the recovery of the parts kinetic energy of the flux. Inventory subject The example is shown in the embodiment in the drawing in a longitudinal section.

Device for carrying out the method according to of the invention is a shaped pre-chamber 1 cylinder cut, on one side limited cylindrical on the insert 2 provided with an axial channel 3 to removal of the yarn 4 and on the other side of the connected by a suction pipe 5 with a vacuum source not.

The chamber 1 has channels 6 along its periphery blowing air that can be placed in any cross-section of the chamber and channel 7 102 221 102 221 3 lead fibers. Inside chamber 1 half at the bottom of the compartment is a cy a cylindrical element 8, which can be a disc, a mushroom or other shaped element. Below element 8 in the chamber outlet, on the suction side the air flow control blades 9, pos relieving to recover partially kinetic energy and turn it into potential.

The way of forcing with this device air is sucked into chamber 1 swirls inside the chamber. Fibers introduced into the chamber in a stream of air in a swirling motion caused by the sucking jet air, forming a ring of fibers 10, high ruining on the inner walls of the chamber 1. Od¬ the sucked air stream hits the element 8, limiting the possibility of rotating flow air from the chamber walls to the core of the wine, thanks why particles having large component wrapping The new velocities flow along the walls of the chamber and the vortex generation effect is reduced, In order to anticipate channel 3, I introduce myself 1 piece of yarn into the chamber, which is rotating ra fibers from the rotating ring 10, yielding 1S when making a turn, and then walks out there are 4 pieces on the outside of the chamber.
