The apparatus suitable for manufacturing ac

yarns securely held by ‘a novel transverse woven

a simple, rugged and efficient mop. In compari
son 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 and- efficient method of manufacturing
mops which will have extreme durability. Other
objects'of the invention will be apparent from
the following description whengread in connec
tion with the drawings, in which like ?gures

be either of the plain or ribbon type. An align- 30
ing board 23 is provided so that all warp strands
will lie in same plane and the harness 24 is pro
vided 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 ad
vanced through the loom providing the unwoven
portion which will form the ends of the mop.
The yarns are advanced through the loom by

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 multi
plicity of moisture absorbent warp yarns in paral 15
lel side to side relationship, weaving said warp
tire 8 is double that of. a single layer. Preferably,
however, multiple layer mops are woven in a
v15 single operation as illustrated by Figures 7 and
10. When the strands are woven in this manner
the path of the shuttle is indicated by the heavy , yarns with a single continuous ?llerstrand so as I

convolutions of said ?ller strand, said ?ller strand
be- apparent that in all cases each strand is ?rm

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,
25 it is possible to interlock the strands by either
knitting or braiding, although it isprobable that
alternate passages of the shuttle during weaving,
and completely encircling each marginal warp
