1 Claim- (01. 28-1) Thisi nvention relates to -improvements in the methods of manufacturing mops and more particularlyl to' 1;, L e'ad'have been commonly annsfof sewing or by the use of a I nt about, the strands to clip the yarns. A common difliculty found with mop heads'fir-iadebyithe' former method is that all the individual strandsa're not sewn since the machine usuallyempioys a relatively long stitch. When stinger the strands are-unanchored it is almost inevitable that the looseyarns will be pulled putduring use and left upon the floor. If a piece of bent metal is clamped about the cords, a point of severe wearing is created where the yarns bend against the metal. -Mop heads of this type commonly fail by cutting of the cords by themetal binder. A further objection to this construction lies in the fact that the metal is apt to scratch furniture and base-boards when themop is in service.

It is the purpose of the present invention to overcome the disadvantages of mops used up to this time. The improved mop head made according to the method of my invention has its yarns securely held by a novel transverse woven binder strip, which effectively prevents disengagement of theindividual strands and comprises a simple, rugged and efficient mop. In comparison with mop heads previously made there are no metal bands or clips which might damage furniture and each cord is individually interlaced with the filler yarns whereby it is securely locked.

The chief object of this invention is to provide a simple andefficient method of manufacturing mops which will have extreme durability. Other objects'of the invention will be apparent from the following description when read in connection with the drawings, in which like figures denote like parts.

In the drawings:--

Figure 1 is a perspective view of a mop head made in accordance with my invention.

Figure 2 is a plan view of a number of unsecured strands and illustrates the first step in the manufacture of mops according to my invention.

Figure 3 is a plan .view of.the strands illustrated in Figure 1, after thesecond step of my invention.

Figure 4 is a plan view of the strands of Figure 3, after the third step of my invention.

Figure 5 is an elevation of apparatus suitable for the manufacturing of mop heads according to my invention.

Figure 6 is a plan view of the apparatus of Figurefi. i t

Figure 7 is a section of a preferred form of mop made in accordance with my invention.

Figure 8 is a section of a modified form of mop.

Figure 9 is a section of still another modification.

Figure 10 is a section of a fourth form of mop made in accordance with my invention.

The first step in manufacturing mops accord- 10 ing to my novel method is the alignment of a large number of strands H, in parallel relationship; when this has been completed a filler strand I2 is woven at intervals with' the longitudinal warp strands, as shown in Figure 3. The last step comprises cutting the longitudinal strands "at points mid-way between the woven portions, forming a plurality of mop sections as shown in Figure 4. It will be apparent that mop heads manufactured according to this method will have a'generally flat conformation and are adapted to be held in their mid-portion by suitable clamping means well-known in the industry.

The apparatus suitable for manufacturing according to this method is illustrated in Figures 5 and 6 and comprises in general a yarn storage rack IS, a loom I! and a cutting table 22. In the apparatus shown the warp yarn ll, isfed from a rack or creel IE, to a loom II, which may be either of the plain or ribbon type. An aligning board 23 is provided so that all warp strands will lie in same plane and the harness 24 is provided to raise and lower the warp strands to permit the passage of the shuttle 25. After a suitable strip has been'woven the shuttle is 3r brought to rest and the warp strands are advanced through the loom providing the unwoven portion which will form the ends of the mop. The yarns are advanced through the loom by the traction on the sand rollers l8, and preferably 40 the yarns are carried under the floor by means of idler rollers I, so that the operator may'have free access to the loom from all sides. At the head of the cutter table 22 a pair of compression rollers 20 are mounted to draw the woven strands over the idler pulleys and onto the table, where the individual mops are separated from each other by manual cutting.

It will be understood that the cycle of weaving, advancing the warp strands and the weaving again is repeated in rotation, one mop being formed during each cycle.

In some cases where the mops are to be subjected to extremely hard service, it may be desirable to tack the loose ends of the filler strands securely in place by sewing them-to the body of the Q mop head. A stitched thread l3 adapted to serve thicknesses of strands be employed. In Figure 9,

this purpose is shown in Figure 1. While a serviceable mop may be manufactured by merely employing a single layer of warp yarns as described above it is desirable that several the path of the shuttle is indicated by the heavy line and the second path by a broken line. b It will beapparent that in all cases each strand is firm- ,ly gripped by the filler yarn and that the various motions of the shuttle may be controlled by means known to the art.

While I have describeda preferred method of forming mops by weaving on a conventional loom, it is possible to interlock the strands by either knitting or braiding, although it isprobable that a loom is more readily adapted to serve the purposes of this invention.

However, I regard my I invention as residing in the steps of interlocking a multiplicity of fibrous yarns by meansof a filler strand and then advancing the yarns for a predetermined'vdistance without interlocking, a

method which may be carried out on knitting or braiding machines.

It is to be'understood that the forms of my invention herein shown and described are to be taken only as preferred examples and that other methods of weaving may suggest themselves to those skilled in the art without departing from the spirit of my invention or the scope of the appended claim. v

What I claim is:

The method of manufacturing mops of the type comprising two groups of endssecured at their central portion by a transverse woven filler strand which comprises the-steps of arranging a multiplicity of moisture absorbent warp yarns in parallel side to side relationship, weaving said warp yarns with a single continuous fillerstrand so as I to enclose each of said warp yarns within the convolutions of said filler strand, said filler strand contacting each of said warp yarns at least at alternate passages of the shuttle during weaving, and completely encircling each marginal warp yarn at each passage of the shuttle; advancing said warp yarns without weaving for a distance greater than that woven, cutting said warp yarns parallel to said filler strands at a point midway between adjacent woven portions and finally securing both endsof said filler strands against unravelling by sewing them to said warp yarns in a direction normal to said warp yarns while the warp strands are maintained in straight alignmentr v PAUL M.
