Park, Old Orchard Beach, Maine, assignor to Saco-Lowell Shops, Boston, Mass., a corporation of Maine Application September 23, 1952, Serial No. 310,960 7 Claims. (Cl. 28-28) This invention relates to slashing and more particularly to a method of slasher operation, together with novel means associated therewith.

In the operating of a conventional slasher or Warp sizing mechanism in which yarns from a number of section beams are sized and assembled onto a single warp beam, it is, of course, necessary from time to time to start a new set of warp yarn ends through the slasher. Heretofore, this has been an operation requiring several hours time, since the new set of yarn ends have commonly been pulled through the slasher, for example, by tying the tail end of the previous warp yarns to the leading end of the new warp. The new yarn ends were then pulled through the size vat and around the dryer cylinders to the head end. At the head end it was necessary to count each of the ends into the comb in the proper order as determined by the pattern of the fabric to be made. The ends so counted were finally wound around or otherwise secured to the warp beam at the head (delivery) end.

The problem of counting the three to five thousand yarn ends into the comb made the above described process a long and tedious one, and, during the time that such ends were being counted into the comb, the slasher was necessarily shut down and a large amount of production was lost.

It is an object of the present invention to provide a method for starting a new set of yarn ends in a slasher without the necessity of shutting down such slasher for a long period of time while the yarn ends are being counted into the comb on the head end.

It is a further object of the invention to provide novel means for carrying out such method in a rapid and efficient manner.

For the purpose of fully describing the preferred method and means of my invention, reference is made to the following drawings in which:

Fig. 1 is a diagrammatic plan view of a slasher adapted to carry out the method of my invention;

F Fig1. 2 is a side elevational view of the slasher of Fig. 3 is a partial side view of a particular device as shown in Figs. 1 and 2 and used in carrying out the method of my invention;

Fig. 4 is a plan view of a portion of another device used in carrying out the method of my invention, and

Fig. 5 is a cross sectional side elevational view of the device of Fig. 4.

Referring to the Figs. 1 and 2 the slasher as used in my invention is conventional as to the size vat and the dryer cylinders 12 and 14. The head end is provided with a conventional beam 16 and with a suitable delivery roll and press rolls 17 as well as a comb 19. The comb 19 is of the expansion type, such expansion comb consisting in general of a series of comb sections 19 mounted in a holding frame modified as hereinafter more fully described.

The creel section of the slasher used in accordance with my invention is arranged with a plurality of creels for holding the section beams 20, a track 22 being provided to permit lateral movement of each of the creels together with their beams into and out or" slashing position. In Figs. 1 and 2 I have shown an arrangement having two creels, a creel 24 in slashing position and a supply creel 26 in counting position adjacent said creel 24 in readiness to be moved into slashing position, each of said creels being provided with wheels 28 so that said creels may be moved transversely along tracks 22.

In general my method comprises first counting the 20 their proper sequence.

2,696,553 Patented Dec. 14, 1954 5 and moving creel 26 into slashing position after the yarn ends from its section beams 20 have been counted into and assembled with comb sections 30; next pulling the counted yarn ends together with the comb sections 31 through the slasher by attaching thereto the end of 0 the old set of yarn ends, and then substituting said new comb sections 30 for the old comb sections 19 at the head end of the slasher.

In order to count the yarn ends 2 from the section beams 20 into comb sections 30 I have provided a leasing 15 stand 32 which in use is placed in position in front of supply creel 26. Such leasing stand is provided with a plurality of rolls on rods 34 on its slanted upper frame member 36, such rolls or rods being desirable to facilitate counting in ends from the several section beams in The rods 34 are preferably arranged in two diverging rows, one above the other to facilitate the separation into a number of sheets corresponding to the number of beams 20.

Near the lower end of said slanted frame member 36 is provided a comb receiving means 38 adapted to receive the locating pins 31 of a plurality of comb sections and to clamp said comb sections in position, suitable thumb screws 39 being provided for such purpose. The comb receiving means 38 may comprise an ex- 30 pansion comb support such as is well known in the art,

such support being modified to permit releasable clamping of pins 31 by thumb screws of the comb sections 30. A roll 40 is provided at the lower end of said frame 36 beyond comb receiving means 38 to support the lower end of yarn ends 2, such yarn ends preferably having a series of weights 42 attached to groups thereof to provide tension for the counting operation.

In use, the leasing stand 32 is positioned in front of supply creel 26. The section beams of said creel 26 are then leased by inserting lease strings into the Warp commencing with the two rear beams as is well known in the art. After all of the lease strings are inserted, the ends of the warp are placed over roll 40 and a sufficient number of weights 42 hung thereon to provide some slight working The lease rods 34 are next inserted and the comb sections 30 are then clamped in comb receiving means 38. Each of the yarn ends is then counted into a comb section and, when all of said ends have been so counted and all of the comb sections 30 are 59 in position in comb receiving means 38, the comb sections 30, together with the yarn ends assembled therein, are inserted into my novel comb carrier apron as hereinafter described, such comb carrier apron for this purpose being supported by a suitable support member 44 on frame 36.

In order to carry the comb sections 30 together with the yarn ends assembled therein through the slasher, I have provided a novel comb carrier apron as best shown in Figs. 4 and 5. Such comb carrier apron includes a body member of canvas or other suitable flexible material having extended leading and trailing edges 51 and 53 respectively of a length at least as great as the width of the sheet of yarn ends to be passed through the slasher. Such sheet of canvas has a plurality of openings 52 along its leading edge 51, the forward edge in respect 05 to its movement through the slasher, such openings preferably being formed in a folded portion 54 of said canvas body member 50 for additional strength. I prefer that such openings be spaced along the leading edge of said canvas member 50 at approximately six inch intervals 74 with the two outer openings 52 close to the outer edges 7 by sewing a canvas pocket member 56 parallel to the long dimension of said canvas body member 50 and approximately centrally thereof along one edge of said pocket member 56 parallel to and toward the leading edge 51 of said canvas member 50 as by stitching 60, leaving Individual comb pockets are preferably formed in said pocket member 56 by stitching 58 extending perpendicular to stitching 60,

such pockets being of a size and number su'fiicient to accommodate comb sections 30.

The trailing edge 53 of the comb carrier apron is pro- =-v1ded with clamp means-for clamping theindividual yarn *ends without'severance thereof. Such clamnmeans 'includes alower clamp bar 62 attachedto trailing edge 53 :o'f canvasmember 50 as by an attaching strip'63-within a "fold-of the canvas of said body member 50. The lower *clamp bar 62 has an-upstanding generally rounded central :.portion which is adapted to fit within a'recess on the bottom surface of an upper clamp bar64.

The upper and- lower clamping members 64 and 62 respectively, may be clamped together with suitable screws -66 passing through upper clamp bar 64 and adapted to-fit'into a tapped hole 68 on lower clamp member66. Adividing "plate 67isprovided-to-prevent fouling of saidscrews 60 by the yarn ends '2. 'The clamping bars when assembled provide means for clamping each of theindividual yarn ends with 'force'sufficient to pull the entire sheet of yarn -ends through the slasher and yet the clampin surfaces have matmg rounded configurations which provide a bight of said canvas-body memberSi) toward comb sections 30.

The' upper clampin g bar 64 is then placed upon the bottom clamping bar =62 with the yarn ends therebetween and the'two clamping members are c amped firmly to ether by screws 66, the dividing plate67 preventin fouling of said screws by the yarn ends. T he weights 42 may then beremoved and thumb screws =39 loosened so that the comb sections 30 may be removed from the comb receivingmeans 38. As it is removed. each comb'section -30 isturnedso'that the free end of the yarn ends therein is wrapped finally around the creel side of the yarn to prevent theyarn from pulling out of the cornb'section. The comb section and yarn is then placed into the apron "pocket behind pocket -member 56 preferably with the comb-section locating pin'31 at the bottom thereof.

After all of the comb sections have been placedin pocket member '56, the lease rods 34, butnot the lease strings. are withdrawn and the comb carrier apron=to- 'gether with thefilled comb sect-ions may beremoved from counting stand 32 andplaced ontop of creel26 in readi- "ness'for'use, all of the above described counting-opera *tionhaving taken place when the slasher is running. with the sheet of yarns supplied by creel 24 in slashing position.

When the yarn ends 2 in the creel 24 in'slashing positional-e about to run 'out, the ends are severed and the exhausted creel '24 moved out of slashing position. The supplv creel 26 is then moved into slashing position along 'rails'22, and the comb carrier apron'is attached to the "ends of-the old sheet of warp yarns 2' in the slasher by tying or otherwise attaching groups of said .endsto the "stitched'holes'52 alon 'the leading edge 51 of the comb carrier'apron. The old sheet of yarns may thus be used -.'to'pull the 'comb :carrier apron together with the new set *of'yarns throughthe slasher, the size vat rolls of course "being'lifted in order to'permit passage therebetween of 'the comb carrier apron. The pull on thenew sheet of -yarn ends is throughthe apron and directly on the clamping-"members 62 and'64 with the comb sections secured in'thepockets of pocket'member '56,since the tension on 'thecomb carrier apron tends to compress these pockets. .Thus, the complete unit with the comb sections and the .yarn assembled therewith may be drawn through the entire slasher onto the head end, the usual lease rods being put in place of the lease strings atthe head end.

When the comb carrier apron arrives at the head end the slasher is stopped, and the comb carrier clamping device placed in support 18. The top press rolls 17 are .thenraised andthe tension of the yarn sheet toward the creel end of the slasher pulls thecomb carrier clamping device firmly into support 18 on said head end, at which time the old yarn ends may be-untied from openings 52 :and the old beam removed and replaced by an empty beam 116. "The old comb sections 19 are then removed from .-.their supportingmeans 38 and the new comb sections 30 with the new yarn ends counted "therein may then reconnected.

slasher comprising :plurality of separated comb sectlons at-the creel end of be placed into said comb section support member 38 on thehead end, said comb sections'being'locatedby'the pin 31 thereon and clamped by suitable thumb screws as with the identical comb support 38 on the leasing stand. The free ends of the new sheet of yarn may then be placed beneath the top'press rolls 17 around delivery roll 15. Thesize vat drive is then-disconnected and the slasher started slowly until the clamping device. is pulled slightly forward ofithesupporting holder. This places the firsttension on the newends afterthey have passed through the new comb sections 30, and tends to equalize the tension on-the yarn on both sidesof comb sections 30. The upper clamping member '64 may then be removed and the entire clamping device =:together with the comb carrier apron removed from the slasher and returned to leasing stand .32Iforre-use, afterwhichithe vat-drive is The new yarn'ends, already counted into the comb sections, are then wound .onthe new beamaat the head end and'the slashenmayithen be started and run without further'delay.

Thusit will be seen that I have provided a novel method and means for starting a new set of yarns through. a slasher, such method and means greatly reducing thetime heretofore consumedin countingthe yarn ends into the comb at the headend of the slasher.

Various modifications of my invention withinthe spirit thereof and the scope of the appended claims will be apparent to those skilled in the art.
