'6 Claims. (Cl. 28-28) This invention relates to improvements in textile slashers, and more particularly concerns a combined textile ber laying (aligning) and slashing apparatus wherein the yarn bers are operated upon to align them along the axis of the ends of yarn, after which the yarn is sized, and then dried.

It is an object of this invention to clean the yarn before it is sized.

It is another object of this invention to lay the yarn bers before the yarn is sized. By laying the yarn bers is meant the aligning of the yarn bers of each individual end of yarn along its axis.

It is another object of this invention to improve the opening of the warp yarn, and to provide a better opening of the warp yarn than at the bust rods.

It is another object of this invention to remove lint, fly, dust, and the like, from the yarn before it is sized.

It is another object of this invention to tack down the yarn bers after the yarn bers are aligned.

Other objects and advantages of this invention, including the simplicity and economy of the same, as well as the ease with which it may be adapted to existing in equipment, will further become apparent hereinafter and in the drawings, in which:

Fig. 1 is a View in elevation of a combined textile ber laying and slashing apparatus constructed and installed in accordance with a proposed form of this invention;

Fig. 2 is a top plan View of the yarn ber aligning mechanism which is one element of this invention. Fig. 2 is taken as indicated by the lines and arrows II-II which appear in Fig. 1;

Fig. 3 is an enlarged View of the yarn ber aligning mechanism with parts broken away in order to illustrate important details;

Fig. 4 is an enlarged view of an end of yarn as it appears before entering the yarn ber aligning mechanism; and

Fig. 5 is an enlarged view of an end of yarn after it has been acted upon by the yarn ber aligning mechamsm.

In describing the preferred embodiment of the invention illustrated in the drawings, specic terminology will be resorted to for the sake of clarity. However, it is not intended to be limited to the specic terms so selected, and it is to be understood that each specic term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.

Turning now to the specic embodiment of the invention selected for illustration in the drawings, the overall arrangement of a combined ber laying and slashing apparatus for yarn is shown in Fig. l, including yarn 11 which is collected from a beam creel (not shown) and is passed between yarn collecting bars 12, then to yarn ber laying mechanism 13, then through spray mechanism 14, and then through a Slasher 15 which includes a size box 16 and a drying section 17.

Yarn 11 comprises a plurality of ends 18 of yarn as is shown in Fig. 2, and each yarn end 18 includes a great number of bers :21 which are haphazardly positioned, as shown in Fig. 4, before the yarn ends 18 enter the yarn ber laying mechanism 13. After passing through ber laying mechanism 13, the yarn bers 21 are aligned along the axis of the yarn end 18 as is shown in Fig. 5.

Laying mechanism 13 includes a vacuum housing 22, having

slots

23 and 24 through which the yarn 11 passes. Rotatably mounted within housing 22 are a pair of cylinders 25, 26 which have brushes 27 and 28 mounted thereon. Cylinder 26 -is provided with a drive shaft 31 which extends through housing 22 and connects with drive motor 32. Cylinder 25 is provided with a drive shaft 33 which extends through slots 34 in housing 22; and is positioned relative to brush 28 by means of adjusting screws 35, which are supported by ears 36 welded to the outside of housing 22. Shaft 33 is driven by motor 32 through gears 37 and 38.

Laying mechanism 13 also includes conduits 41 which connect the interior of housing 22 to an exhaust blower 42 which discharges the lint, y dust, and the like, removed from yarn 11 by laying mechanism 13. Blower 42 discharges such material into the mill dust collecting system (not shown).

The yarn 11 having been brushed and cleaned, and the yarn bers 21 having been laid, the yarn 11 passes to spray mechanism 14 which sets (tacks down) the aligned bers 21. Spray mechanism 14 includes a housing 43 having slots 44, 45 through which the yarn 11 passes. Within housing 43 there are mounted spray nozzles 46 which direct a liquid spray toward the yarn 11 to set (tack down) the alignment of the bers 21. Spray mechanism 14 also includes a liquid supply reservoir 47, a pump 48, and

pipes

50, 51 which connect nozzles 46, pump 48, supply reservoir 47, and housing 43.

Size box 16 is of conventional design and includes a well containing a sizing liquid or slurry, a steam jacket 53, a carrier roll 54, an immersion roll 55, and squeeze rolls 56. Drying section 17 is also of conventional design and includes the drying cylinders 57.

In operation, warp yarn 11 is collected from a beam creel (not shown) and is passed between yarn collect- -ing bars 12 to yarn ber laying mechanism 13 where the yarn 11 is brushed and cleaned and the yarn bers 21 are laid. Then the warp yarn 11 is passed through spray mechanism 14 where it is subjected to a liquid spray from the nozzles 46 which tacks down the bers 21. After this, the Warp yarn 11 is passed through a Slasher 15 where it is immersed in the sizing slurry, and then is passed through the squeeze rolls 56 and the drying section 17, which includes a number of heated drying cylinders 57.

In the laying mechanism 13, the lint, fly, dust, and the like, are removed from the warp yarns 11 by the brushing and are sucked out through conduits 41 and exhaust blower 42.

In the spray mechanism 14, the pump 48 pumps the spray liquid from the liquid supply reservoir 47 through the piping 51 to the spray nozzles 46. The excess spray liquid drops to the bottom of housing 43 and is collected and returned through the piping 50 to the liquid supply reservoir 47.

The brushing of the yarn 11 before it is sized acts to clean the yarn, and to lay the yarn bers 21. This brushing also provides a better opening of the warp yarn than at the bust rods.

The lint, y, dust, and the like, are removed from the Warp yarns 11 by being sucked out through the vacuum system and discharged into the mill dust collecting system or similar device.

The spray 14 directs an atomzed spray of liquid which may be water, a 'wetting agent, or a size solution, to

the yarn 11 after it has been brushed, and thus tacks down the yarn ber before the yarn 11 enters the size box 16. This helps maintain the alignment which was imparted to the yarn bers by brushes 27, 28.

The brushes 27, 28 clean the yarn 11 and lay the yarn bers. Another result of brushing is the improved opening of the warp yarn at the bust rods (not shown) which yis the result of the improved alignment of the yarn bers. The alignment of yarn bers lessens the tendency of the ends 18 of yarn to become stuck together.

The brushes 27, 28 are preferably made of wire or nylon brush material. Their speed or rotation is controlled independently of the slasher 15 and independently of the speed of the warp yarn. Brushes 27, 28 are preferably rotated at a considerably higher rate of speed than the speed of the warp yarn 11. f

Excellent ber alignment is obtained by the brushing operation and this alignment is made relatively permanent by the operation of dipping yarn 11 in the size box 16.

It is to be understood that the form of the invention herein shown and described is to be taken as a preferred embodiment. Various changes may be made in the shape, size and arrangement of parts. ments may be substituted for those described herein, parts may be reversed, and certain features of the invention may be utilized independently of the use of other features, all without departing from the spirit of the invention or the scope of thesubjoined claims.
