1 Claims. (01. 28-28) The present invention relates to an improved method and apparatus for setting up a slasher for operation upon a new warp.

In the operation of a slasher the threads or ends which comprise the warp are drawn from a number of section beams of a creel in the form of a fiat sheet which is passed through the sizing device, around one or more drying drums where the sizing material is baked onto the threads,

and are finally wound onto a warp beam at the front end oi the machine ready for weaving. These threads or ends must occupy a substantially parallel relationship during the passage oi the warp through the slasher, and more particn- I larly as they are wound onto the warp beam, for satisfactory operation when they are later threaded into. the heddles or harnesses of the loom for weaving. In order to facilitate guid-' ing the threads and to insure that they are maintained in the required parallel relationship as they are wound onto the warp beam, it is customary to pass the threads in groups or sheaths through the dents of a separating comb mounted on the forward end of the machine from whence they pass around the take-up feed roller to the warp beam.

In the setting up of a machine of this type i'or operation with a new group of section beams, it is the usual practice to draw the threads or ends of the new beams from the creel, tie them in bunches to the ends severed from the exhausted beams, and then turn over the machine so that the new ends are drawn through the machine to the separating comb above referred to. The new ends are then counted in, which consists in arranging the threads in their proper order and with the proper number in each of the dents of the comb, and are attached to a fresh warp beam.. The machine is now ready to be started.

- The process of drawing the new ends from the creel, and more particularly of counting in the new ends in the separating comb at the for-- ward end of the machine, is a long and tedious business which may keep the machine idle consecutively from'two to eight hours depending upon the number of ends in the set, and upon whether colored yarns are to be used.

It is the object of the present invention to provide a novel and improved method and apparatus for employing the same which will permit the setting up of the slasher for operation upon a new warp or set to be accomplished in a small fraction of the time previously required, so that the machine may be kept substantially in continuous operation with the corresponding improvement in emciency and economy of operation.

With this and other objects in' view, as may hereinafter appear, the several steps of the 5 method employed, and the several features of the apparatus utilized in setting up a. slasher for operation with a new set of section beams as hereinafter described and claimed, will be readily understood by one skilled in the art from the iol- 1o lowing description taken in connection with the accompanying drawings, in which Fig. l is a somewhat diagrammatic view in side elevation of a slasher, only so much oi the machine being shown as is necessary to illustrate the manner in which the applicant's method is applied there to for the setting up of the slasher for operation upon a fresh set of section beams; Fig. 2 is a view on an enlarged scale of a creel and a counting-in frame associated therewith to illustrate certain steps of applicants method and disclosing in a preferred form the several features of the apparatus employed in connection therewith; Fig. 3 is a somewhat diagrammatic plan view oi a slasher having the general organization of parts shown in Fig. l, and illustrating particularly an alternate creel, together with two counting-in. frames and a supporting track on which the creels may be moved readily into and out oi operative position with relation to the chine; and Fig. 4 is a fragmentary plan view on a greatly enlarged scale, showing the manner in which the threads are counted in in sheaths on the comb oi the counting-in frame and leased for subsequent placing in the separating comb at the forward end of the machine.

The drawings disclose a slasher of the type disclosed in the patent to Slipp, No. 1,553,4i3,

dated September 15, 1925, and in the patent to Cook,'l lo. 1,944,221, dated January 23, 1934, to 40 gether with novel apparatus which is well adapted to assist the operator in the practice of the method of the present invention, and which embodies certain features of invention as hereinafter to be more fully set forth.

While the slasher herein illustrated is particularly well adapted for the practice of the several steps of applicant's method,.it is to be understood that applicants method of setting up the slasher for operation is equally applicable for setting up 5; slashers of other types, in which the new threads or ends must be sorted or counted in to pass through a supporting comb at the forward end of the machine for winding onto the usual warp beam.

Referring more specificalh' to the drawings, Fig. 1 is a somewhat diagrammatic view in side elevation of a preferred type of slasher which comprises a main drying drum 20, a smaller drum 22 mounted on a frame 24, a size bath having two size rollers 26 and cooperating press rollers 20, a creel 30 having supported thereon a plurality of section beams indicated generally at 32, 34, 30, 30 and 40 respectively, a warp' beam 42 onto which the warp is wound, a warp feeding device comprising a feed roll 44, and a separating comb 48 mounted adjacent to the warp beam 42 at the forward end of the machine. There is also mounted between the creel and the size bath a warp stretch control device which includes a positively driven draw-off feed roll 48 for drawing the ends or threads from the several section beams of the creel 30. The feed roll 44, the drums 20 and 22, the sizerolls 26 and the stretch control feed roll 48 are all driven in timed relation through driving means which may be of any ordinary description, but are herein disclosed as comprising a drive shaft 50 extending along the side of the machine, and connected at one end through a bevel gear and pinion.52 to the drive for the feed roll 44, and at its other end through a bevel gear and pinion 54 to the size rolls 28. The drums 20 and 22 are respectively driven from the shaft 50 through gear connections not shown which are housed respectively in gear boxes 56 and 58. The stretch control feed roll 48 is driven from one of the size rolls 26 through a chain drive generally indicated at 60.

To facilitate the practice of the applicant's method of setting up the slasher for operation upon a new warp, the slasher shown in the drawings is provided with two creels which are mounted on cross rails 1'0, so that the creels can be moved alternatively into and out of operative position at the rear of the slasher. With the present machine there are also provided, as best shown in Figs. 2 and 3, two counting-in frames 12 which are located one at each side of the slasher for use in connection with the spare creel to prepare a new warp for setting up on the slasher. Each of the frames I2 is provided with a guide roll 14 and a counting-in comb 1'6 which has teeth equal in number to the teeth of the separating comb 48 mounted on the forward end of the slasher. The relative positions of the spare creel and the counting-in frame for setting up a new warp during the continued operation of the slasher with the alternate creel, is clearly shown in Figs. 2 and 3.

The several steps of applicants novel and improved method of setting up the slasher for operation upon a new warp may be described as follows:---

It may be assumed that fresh section beams have been placed on the spare creel. The threads are first drawn off therefrom in accordance with the usual practice where the creel is permanently mounted behind the machine. The ends from the last section beam in line designated at 18 (Fig. 2) are drawn over the section beam where the additional ends are picked up and drawn around the section beam 82. In a similar manner the ends are drawn around the section beams 84 and 86, the additional ends from each added beam being picked up to form the entire warp.-

Further, in accordance with the usual practice, lease strings are laid consecutively between the threads or ends of each section beam and those added thereto from previous beam or beams as the ends are drawn through the creel, so that the ends from each section beam can later be split or separated from the ends of each of the other section beams. The manner in which these lease strings are laid in is clearly shown in Fig. 2, in which lease strings 00, 80 and 92 are indicated in dotted lines, having been laid in consecutively as the ends pass onto the section beams 80, 82 and 04 respectively. A lease string 04 as shown, has been laid onto the section beam 86, so that when the ends are subsequently drawn still further through the creel, the ends from the section beam 86 will be similarly separated out from the ends of the previous beams on the creel. These lease strings are subsequently drawn through the slasher with the warp, and serve to enable the operator in setting up the machine to position the lease rods 96 through the warp to split the threads or ends which may have become stuck together during the sizing and subsequent drying operation on the drums 20 and 22.

The ends of the warp drawn through the creel are now passed over the guide roll 14, and" are laid over the forward end of the counting-in frame 12, where they are tied in bunches to weights 98 preparatory for the operation of counting in the ends in the dents of the countingin comb 16. It is the task of the operator next to sort the ends and place them in parallel relationship in groups or sheaths in the dents oi the comb 16. The manner in which this operation of counting in the threads is carried on is best shown in Figs. 2 and 4. As shown in Fig. 4, four threads or ends are placed in each dent between two adjacent teeth I00 of the countingin comb. It will be understood that the number of ends in each sheath may be varied in accordance with the requirements of the particular set, and may vary from one to six or seven as desired. After all of the ends have been sorted and counted in on the counting-in comb 16, so that the threads occupy a parallel relationship and have been placed in even groups of four each in the dents of the comb 16, the operator next places a lease string I02 in the warp to maintain the alignment and division of the ends during the subsequent operation of pulling the warp through the machine, so that they may be readily placed in the corresponding dents of the separating comb 46 at the forward end of the machine. lease string I02 is conveniently carried out by means of a leasing tool I04, which, as best shown in Figs. 2 and 4, comprises a U-shaped wire having one end thereof bent upwardly and the other end bent downwardly. The operator inserts this tool into the edge of the warp adjacent the comb 16 following the division indicated by the dents of the counting-in comb 76, so that the ends of each succeeding group or sheath will pass alternatively over and under, and under and over the two arms of the tool I04. After a number of the sheaths have been sorted out by means of this tool, the tool while still engaged within the warp is pushed rearwardly' over the guide roll 15, and the lease string I02 then passed around the separated groups or sheaths at a point about midway between the guide roll 14 and the creel. The tool is then withdrawn from the warp, and is again inserted adjacent the comb 16 to pick up the next succeeding sheaths or groups. In this manner the lease string I02 is threaded through the entire warp at a. distance as far removed as possible from the leading end of the warp, so that a minimum risk is incurred of disarranging the groups or sheaths during the The operation of placing in the aosarcc subsequent operations oi tying the warp ends to the severed ends of the old warp and drawing thenew warpthrough the machine. After the lease string ldl has been fully threaded through the warp, the weights dd are detached, and the whole warp is then thrown back over a support ing roller tilt; carried on a standard lllli on the forward end of the creel ready for use. "the dper atiorls above described, of drawing the ends through the creel and the counting in. of the threads, together with the subsequent leasing of the sheaths by means of the lease string are carried out preferably while the machine is in operation with the alternate creel. Inasmuch as this operation oi counting in the ends requires extremely careful and painstaking worlr, and may talse from two to eight hours depending upon the size and complexity oi the set, it will readily be seen that a very considerable saving is effected in the time in which it is necessary to keep the slasher idle in introducing a new set into the machine. Further considerable saving is effected in making up the new set on an alter hate creel in accordance with applicants method, owing to the tact that taslr. ct setting up and counting in the ends the new warp may he performed, in connection with applicants leasing frame, by unskilled labor, whereas with the old method of setting up, counting in oi the new ends at the forward end oi the machine was performed by the operator or the slasher, who is necessarily a high priced man or" considerable experience and shill in the operation of these machines.

ltlhen the section beams of the creel operating in the machine run out, relatively little time is consumed by the operator in setting up the machine for operation with the alternate creel. First oi all the machine is stopped, a certain amount of thread is drawn off from the exhausted creel, and the ends are severed, so that the crhausted creel can be moved on the rails id out of operative position. The newly prepared creel is now moved into position bel'rind the machine, the ends are tied in hunches to the severed ends of the finished warp, and the machine is started to draw the new ends through the machine. Durlog this operation the separating comb it can be removed or a rod inserted to carry the bunched ends over the top of the comb and around the teed roll The machine is then. stopped and the finished warp beam removed and an empty one inserted in its place. The new ends are clamped onto the new beam in the usual manner, and the new ends are laid into the dents of the separating comb lb in accordance with the arrangement and grouping indicated by the lease string ltd. slowly while the operator places inthe lease rods lit as indicated by the respective lease strings lit, 9t], lit and ill, so that the machine is ready for operation on the new warp.

It will be noted that the teeth of the separating comb lit and or the counting-in comb it are open at the top, so that the ends play he held under tension at all times during the operations of counting in the threads on the leasing frame and subsequently or positioning the sheaths in the dents of the supporting comb at the forward end of the machine, thus greatly facilitating the work of the operator or operators in handling the threads.
