Definitions
- This invention relates to an apparatus for applying liquid finish to a moving continuous filament yarn. More particularly, it relates to an improved groove-type finish applicator that provides uniform finish application to a moving continuous filament yarn with a capability to compensate for yarn misalignment in the slot.
- U.S. Patent No. 4,397,164 of common assignee discloses a yarn finish applicator in which finish is metered to a slot running from top to bottom of the applicator.
- the configuration of the body of the applicator and its slot provides an edge at the exit end of the applicator and a slot that is slightly wider at the location at which finish is metered to the slot than at exit of the slot.
- the yarn finish applicator includes a body member that has top, opposed side, front and back surfaces.
- a slot with bottom and side walls is formed in the front surface running from top to bottom of the body member.
- the slot has bottom and side walls with a passage connecting the back surface of the body member through which is metered the desired quantity of liquid finish.
- the lower portion of the front and back surfaces of the body member are angled downwardly toward each other and in conjunction with the opposed side surfaces which taper downwardly toward each other form an adge at the bottom wall of the slot.
- the side walls of the slot taper inwardly toward the bottom wall while tapering toward each other frm top to bottom.
- GB-A-2079189 discloses an apparatus for moistening textile yarn before passage of the yarn to a pressurising texturing jet.
- This comprises a liquid tank and a moistening device comprising a die with a longitudinal bore connected to the tank outlet and having a flow regulator located in the the tank's liquid inflow pipe.
- the present invention provides an improvement in the apparatus described in U.S. Patent No. 4,397,164.
- the passage supplying liquid to the slot extends through the bottom wall and partially up the side walls of the slot to provide a uniform finish application regardless of threadline alignment within the slot.
- the yarn finish applicator of the invention comprises a body member having top opposed side surfaces and front and back surfaces and a slot in the front surface running from top to bottom, said slot having bottom wall and side walls, and a passage connecting the back surface of the body member to the slot for supplying finish to said slot.
- the passage is of substantially rectangular cross-section and connects said back surface of the body member to said slot by extending through the bottom wall of the slot and through a portion of each side wall adjacent to said bottom wall. The height of the side wall portions of the slot do not exceed 25% of the width of the bottom wall.
- Fig. 1 is a perspective view of the finish applicator of this invention.
- Fig. 2 is a cross-sectional view of Fig. 1 taken along line 2-2.
- Fig. 3 is an enlarged view of the cross-sectioned applicator body member as seen in Fig. 2.
- Fig. 4 is an enlarged front view of the applicator body member.
- the embodiment chosen for purposes of illustration includes an applicator body member 10, a pipe 13, and a bracket 15.
- the pipe 13 is held in a bore through the upper portion of bracket 15 by means of a set screw 17.
- the pipe is connected to a source of liquid finish (not shown) by means of fitting 19.
- the applicator body member 10 which is cemented into the outlet end of pipe 13 has a top surface 12, opposed side surfaces 14, 16 and a front surface 22 which terminates in a lower portion 22a.
- the slot 20 runs from the top surface 12 to the bottom of the applicator body member and is defined by side walls 24, 26 and bottom wall 28.
- a passage 30 is configured to connect the back surface 22 of the body member with the bottom wall 28 and sidewalls 24, 26 of the slot for supplying a liquid finish to the slot.
- the passage 30 extends through the bottom wall 28 and through a portion 24a, 26a of each side wall 24, 26, adjacent the bottom wall.
- the side wall portions of passage 30 do not exceed 25 percent of the width of bottom wall 28 where the slot 30 extends through the bottom wall.
- the yarn 11 runs from top to bottom of the applicator as indicated by the arrow.
- the slot 20 is defined by side walls 24, 26 and a bottom wall 28.
- the side walls 24, 26 taper inwardly toward each other as they approach bottom wall 28 and also taper toward each other as they progress from top to bottom of the applicator body member.
- the configuration of the slot 20 is a critical feature of the invention. More particularly, the slot is tapered where the filament bundle of the moving yarn line 11 contacts the bottom wall 28. Finishing liquid is applied to the yarn at the initial point of contact with the bottom and/or side walls of the slot, as the case may be; i.e., at passage 30.
- the yarn picks up finish at the point of initial yarn contact with the bottom wall or side walls of or both of the slot depending on threadline alignment in the slot at the location where finish is introduced through passage 30 and carries it forward along the tapered slot 20 and exits the slot tangentially with the bottom surface 28 with no separation between the bottom surface 28 and the threadline.
- the combination of the fully wiped bottom surface and the tangential exit of the yarn from the slot permits all of the finish to leave the slot with the yarn giving a uniform finish application on the yarn without the formation of drops at the exit end of the applicator.
- the applicator of this invention may be used to apply liquid materials which are not harmful to the yarn or the applicating system.
- liquids which may be applied are solutions, dyes, dispersions, or emulsions of conventional treating agents such as lubricants, antistatic agents, binders, softeners and the like.
- the liquid may be applied to such man-made continuous filament yarns as, for example, polyamides, polyesters, polyacrylics, spandex, rayon, and cellulose acetate.
