5 Claims. (CI. 2840) This invention relates to a warp beaming apparatus and its primary object is to provide a construction and arrangement thereof adapted to facilitate lacing up and leasing.

The more specific objects and advantages of the invention will be apparent from the drawing and description thereof. In the drawing, which is merely illustrative of one embodiment of the invention Figure 1 is a side elevation, partially diagrammatic, of a warping system with the invention in position,

Figure 1a. is a side elevation, somewhatenlarged, of the eye-bars. of Figure 1, I

Figure 1b is a side elevation corresponding to e that shown in Figure 1a but illustrating a modiflcation of the eye-bars, v

Figure 2 is a plan view of a part of the system of Figure 1,

Figure 3 is a front view of the eyeboard of Figgure 1, and

Figure 4 is a, plan view of the lease rod.

In beaming, a multiplicity of yarns are drawn from a creel or equivalent yarn supply through suitable guides and tension-controlling devices mounted on the creel or supply frame. As they leave the creel, they generally pass through an eyeboard and through thread-breakage detector devices either on the eyeboard or in front thereof or each positioned in association with a given of the barsiere Preferably laterally Offset QO supply package in the creel. Between the creel the enenzmt Vely e g guidgs 111316 other and the delivery roll for feeding the yarns to the t As shewn' t e are formed beam take-up, the yarns heretofore were divided of channels and are Secure? together by end into two or more sheets by passing over and under Plates Instead charm; n emss one or more lease rods or bars positioned in back f zgggg gi g gg z?fiy g i'z g zge ga' og an expat-Bible just back of the delivery may be substituted for the two, the guides ii roll.

This practically minimizes the danger operator inserts by hand. This leasing operation of the lease rod catching the yarns as it is inis time-consuming and requires great care and serted by the operator. efiort on the part of the operator to be sure that Means is provided for adjusting the overall lib width of the sheets. This may comprise pivtheleasing rod he inserts by hand does not catch 2 upon the yarns of the sheets above or below the rod.

In accordance with the present invention, a'

merous supply packages 2 in the creel 3. As they leave the creel they pass through the guides provided in the eyeboard l which may be provided with suitable breakage-detectors 5 which are con-.

nected in conventional fashion to stop the warp beam upon the breakage of the yarn. Thereupon, the yarns converge and proceed through the guide I means provided at 6 from which they emerge as a plurality of separate sheets, two being shown in the specific embodiment and designated A and B. The yarns then proceed about the delivery roll I to the take-up beam'8 which may be driven by a motor 9 through a belt Ill. The driving and stopping connections are not shown in detail since these may be conventional.

The guide means 6 comprises a plurality of vertically offset guiding means. As shown, (Figures 1 and In) these may comprise a plurality of guides, such as eyes H of porcelain set within vertically spaced bars [2. The guides ii in one otally mounting the eye-bars 12 upon an axis IS. The adjustments can be made by the operator by means of the hand wheel [6 on the screw H which engages a thread in the mounting bracket l8. The endwise motion of; the screw I! may be transmitted through a universal coupling is and rod 20 to the bracket 21 secured to the eye-bars 12.

Means is provided for laterally shifting the entire guide means 6 as a. unit in order to compensate for variations in beam widths. This lateral moving means comprises a slidable supporting block 25 in which the shaft I is pivotally mounted. The block 25 is slidably supported upon a base 26 and has a screw thread engaging the screw 21 which is adjustable by means of the hand wheel 28. The shank of the screw 21 is freely rotatably mounted in a bearing 29 and is prevented from axial movement by means of collars which are fixed to the shank on either side of the bearing 28.

In operation, the yarns are divided into a plurality of sheets, each of which is constituted of alternate yarns. The yarns in a given sheet are passed through the individual guides H in one of the vertically spaced eye-bars l2. During beaming, the operator may from time to time adjust the overall width of the sheets by turning the hand wheel l6 one way or the other. Whenever it is desired to lease, it is only necessary for the operator to insert between the sheets, as A and B, a flat lease rod 22 (see Figure 4), over the free forked end 23 of which a paper strip is folded so that adouble thickness thereof is left between the sheets. This insertion is greatly facilitated by the fact that the guide means 6 maintains the sheets separated so that no preliminary manipulation is required to separate the yarns into sheets, such as was required heretofore, and when inserting the lease rod, it may he slid into the space between roll I and guide means 6 over the ledge a or ll, as illustrated in Figure 2 particularly in which such lease rod is designated R. The leasing may otherwise follow conventional procedure. For example, the paper strip thus inserted between two sheets is moved sideways into position on top of roll 1 but still between sheets A and B.

At this point, an adhesive tape may be applied over the assembly on the delivery roll, Then the beam may be rotated until the paper is brought to the top of the beam and another adhesivetape may then be applied to the outside of the assembly. This produces a plurality of separable groups of yarns, the yarns in each group being held together by the adhesive tapes. Thereafter, if the beam is full and an empty beam is to be substituted, the yarns may be out between the roll I and beam-8 and tied together to prevent them from passing back through the guides ll of the eye-bars. An empty beam may be substituted and the yarns laced about the new beam in the conventional manner.

Since the guide means 6 of the present invention replaces both the expansible comb and the lease rod or rods which normally remain in position during beaming in the manner heretofore practiced, the system of the present invention has fewer rubbing surfaces against which the yarns engage and consequently it is particularly valuable when it is desired to beam yarns comprising filaments of a delicate nature, such as artificially produced filaments or fibers of extremely small diameters, including low denier rayon or low denier resin or nylon filaments.

It is to be understood that changes and varia- 4 tions may be made without departing from the spirit and scope of the invention as defined in the appended claims.
