1 Claim.

This invention relates to textile apparatus, and relates more particularly to apparatus for unwinding or cleaning yarn from a yarn package and to Huid-operated jet means employed in connection with said apparatus.

As is well known, it is often necessary to unwind the yarn from yarn packages when the yarn is soiled or damaged or when the length of yarn on the package is below a given minimum. It has hitherto been customary to ycarry out this unwinding operation manually or by means of motor driven unwinding apparatus which was of limited utility in that it required large amounts of labor and operated at relatively low speeds.

It is an important object of this invention to provide an apparatus for unwinding yarn from yarn packages which will be more eiiicient in operation and simpler in construction than apparatus hitherto employed for this purpose.

A further object of this invention is to provide an apparatus for unwnding yarn from yarn packages in which a Huid-operated jet means is employed to draw the yarn from the yarn packages.

Another object of this invention is to provide a novel duid-operated jet means for transporting yarn.

Other objects of this invention, together with certain details of construction and combinations of parts, will be apparent from the following detailed description and claim.

In its broadest aspect this invention comprises an apparatus 4for unwinding yarn from yarn packages in which a fluid-operated jet means is employed to draw the yarn from the yarn packages. The apparatus of this invention may be employed for unwinding yarn from various types of yarn packages such as pirns, bobbins, spools, cakes, etc. Depending upon the neness of the yarn, a single fluid-operated jet means will simultaneously unwind the ends from l to 100 or more yarn packages delivering the yarn to any suitable type of receiver such as a waste can. The speed with which the yarn is unwound will vary depending upon the fluid pressure employed, the rate of fluid iiow, the iineness of the yarn and the number of ends being simultaneously handled, and may range from 100 to 3000 or more yards per minute. The fluid employed to operate the jet means will generally be air since it is the least expensive and may be used in an open system exhausting to the atmosphere. However, other fluids may be employed, if desired. Fluid pressure may range from 25 to 500 or more pounds per square inch and flow rates may range from 0.1 to 20 or more cubic feet per second, the particular pressure and rate of flow depending upon the iineness and number of ends of yarn being simultaneously unwound, as well as upon the speed desired.

In carrying out this invention the yarn packages may be supported in any desired manner. For example, the yarn packages may be supported on a transport holding from 25 to 100 or more packages, or on a table provided with suitable package supporting means. The yarn may pass directly from the yarn packages to the fluid-operated jet means or may pass over or through any number of suitable guides before reaching said jet means. From the duid-operated jet means the yarn may pass directly into a suitable receiver such as a waste can or the yarn may pass through or over one or more yarn guides before reaching said receiver. It is preferred to employ conduits as yarn guides since the fluid continues to transport the yarn as it passes through said conduits. When a plurality of ends are being simultaneously unwound from a number of yarn packages each end may be individually threaded into the :duid-operated jet means, or each succeeding end may be laid over yarn passing to the Jet means and will be carried into saidjet means by said yarn.

This invention also comprises a novel Huidoperated jet means for transporting yarn in which the rate of fluid flow may be readily adjusted during operation to control the speed ofv the yarn. Means may also be provided to limit the maximum amount of fluid which may be passed through the jet means, thereby to avoid any waste of fluid and to render the operation of the jet means substantially fool-proof. In addition, the uid-operated jet means may be constructed so that the flow of iiuid therethrough may be cut 01T completely to permit shutting down of the apparatus in which said jet means is employed.
