Textile slasher lubricating apparatus

Claim 2

Apparatus for preparing individual warp yarn ends wound upon a loom beam for weaving on a textile slasher of the type including means for passing a sheet of the individual textile warp yarn ends arranged generally side by side through said slasher and for applying a sizing to said warp yarn ends, and dryer means for drying said warp yarn ends to which said sizing has been applied, said apparatus comprising: a pair of rotating porous lubricating rods carried on a frame in a path of said warp yarn ends passing through said slasher adjacent said dryer means; said pair of porous lubricating rods being arranged generally in a vertical plane on said frame; drive means for rotating said porous lubricating rods at a rotational speed proportional to the speed of said slasher; a source of lubricant connected to said porous lubricating rods; metering means for metering the amount of lubricant from said source delivered through said porous lubricating rods onto said warp yarn ends controlled in response to the operational speed of said slasher; and said warp yarn sheet passing over a first of said lubricating rods and under a second of said lubricating rods in a manner that a desired percentage of add-on weight of said lubricant is metered and applied to said warp yarn ends by said metering means in response to the operational speed of said slasher.

Claim 3

The apparatus of claim 1 wherein each of said porous lubricating rods includes a porous hollow rod having a porous lubricant distribution layer terminating in a continuous lubricant application surface; an inner flow control membrane formed at a boundary region of said porous distribution layer; and said flow control membrane having a porosity not greater than the porosity of said lubricant distribution layer to meter the flow of lubricant onto said lubricant application surface and said flow control membrane forming a part of said metering means for metering said lubricant through said lubricating rods onto said warp yarn ends.

Claim 4

Apparatus for use in a slasher of the type wherein warp yarns arranged generally side by side in a sheet are processed by means for applying a sizing to said warp yarns, means for drying said sized warp yarns, and means for subjecting said dried warp yarns to a busting process wherein said warp yarns are separated into a number of individual sheets of said side by side warp yarns prior to being wound upon a loom beam for weaving, said apparatus comprising: a pair of porous lubricating rods located after the drying means including a first porous lubricating rod having a hollow interior and a second porous lubricating rod having a hollow interior; a non-deformable porous lubricant application surface formed continuously about an exterior of each said rod; said warp sheet passing over one of said lubricating rods and under the other such rods for application of lubricant to the warp yarns thereof; a frame for rotatably carrying said porous rods in a unitary spaced apart manner; drive means for rotating said porous rods in unison responsive to the operational speed of said slasher; metering means for delivering a metered volume of lubricant to the hollow interiors of said first and second porous rods; means for sensing the quantity of said warp yarns passing through said slasher and delivering said volume of lubricant to said lubricating rods in response to said sensed quantity of said warp yarns; a rotary union connecting the end of each said rotating porous rod to said metering means; and means for arranging said frame and said pair of porous lubricating rods generally in a vertical plane on said slasher.

Claim 5

Apparatus for use in a slasher of the type wherein warp yarns arranged generally side by side in a sheet are processed by means for applying a sizing to said warp yarns, means for drying said sized warp yarns, and means for subjecting said dried warp yarns to a busting process wherein said warp yarns are separated into a number of individual sheets of said side by side warp yarns prior to being wound upon a loom beam for weaving, said apparatus comprising: a pair of porous lubricating rods located after the drying means including a first porous lubricating rod having a hollow interior and a second porous lubricating rod having a hollow interior; a non-deformable porous lubricant application surface formed continuously about an exterior of each said rod; said warp sheet passing over one of said lubricating rods and under the other such rods for application of lubricant to the warp yarns thereof; a frame for rotatably carrying said porous rods in a unitary spaced apart manner; drive means for rotating said porous rods in unison responsive to the operational speed of said slasher; metering means for delivering a metered volume of lubricant to the hollow interiors of said first and second porous rods; means for sensing the quantity of said warp yarns passing through said slasher and delivering said volume of lubricant to said lubricating rods in response to said sensed quantity of said warp yarns; a rotary union connecting the end of each said rotating porous rod to said metering means; and means for arranging said frame and said pair of porous lubricating rods generally in a vertical plane on said slasher.

Claim 6

The apparatus of claim 3 including spaced guide means carried by each said lubricating rod for containing and guiding said warp yarn sheet over said porous application surface.

Claim 7

The apparatus of claim 3 wherein each said porous lubricating rod includes a porous lubricant distribution layer in the form of a continuous cylindrical porous layer extending from said interior of said rod to said porous application surface; a flow control membrane formed at a boundary region of said porous distribution layer having a porosity less than that of said distribution layer to meter the flow of lubricant onto said lubricant application surface.

Claim 8

The apparatus of claim 3 wherein said means for arranging said frame and porous lubricating rods on said slasher includes means for adjustably arranging said frame in a desired inclination on said slasher so that said warp yarn sheet may pass through said frame without contacting said porous lubricating rods.

Claim 9

The apparatus of claim 3 wherein said sensing means includes a cam actuator carried by a rotating shaft driven in response to the speed of said warp yarns through said slasher; and a detector carried by said frame of said lubricating rods actuated by said cam actuator for controlling said means for metering said volume of lubricant to said porous rods.

Claim 10

The apparatus of claim 3 wherein the pores of said porous application surface have a mean dimension which is smaller than the filament diameters of multifilament yarn when processed passing over said porous surface.
