Abstract
A mop head uses a ribbon of non-woven absorbent synthetic material folded lengthwise in multiple thicknesses. The ribbon is formed into a coiled wrapping which is collapsed centrally to provide opposite arms and a center of double thickness with top and bottom layers. A center strip of binder material extends longitudinally in this position between the top and bottom layers. Spaced rows of stitching secure the center strip to the top and bottom layers.
Description
FIELD OF THE INVENTION
This invention relates to cleaning mops and materials and the method for making same which uses inexpensive, generally waste materials.
BACKGROUND OF THE INVENTION
Cleaning devices, mop and wipes and covers have historically been made from cotton or synthetic fibers which are twisted and formed into strands and the strands formed into yarns. The yarns may be woven on looms to produce sheet form goods. These woven fabric articles are made in more or less degrees of costs. An alternative to traditional fiber yarns has been the use of non-woven cellulose/wood pulp fabrics such as used in tea bags, food and industry machine filters, disposable uniforms, packaging, paper wipes, facial tissue, paper towels and the like. Waste products result from the manufacture of these items. Applicant's invention provides a novel approach to the use of these waste products. A strip of inexpensive or waste material is folded and center stitched to create a multiple thickness ribbon which may serve as a yarn substitute. Mops can be made using this yarn substitute ribbon. A mop made using this type of yarn substitute provides an inexpensive mop which is an alternative to inexpensive mops which have typically used the cheapest fibers or reclaimed fibers in the spinning process. Other mops have used stacks of fabrics from which strips are cut to form flat ribbons or strings and yet others have processed non-woven materials using special stretching and twisting techniques which reduce absorbency but add sufficient strength to make a useful mop or other cleaning device. Some are less or more absorbent than others and some are sturdier in use than others. The present invention presents a novel solution to the disposable cleaning article and mop problem by providing a strip or ribbon of material which is formed into a mop which retains its shape, strongly secured at its headband and is absorbent yet sufficiently robust to provide effective scrubbing and cleaning ability. Disposable mops can be made using the disclosed method.

DESCRIPTION OF THE PREFERRED AND ALTERNATE EMBODIMENTS
As required, a detailed description of the preferred is disclosed herein, however, other embodiments or configurations may be apparent based upon the following description to those having ordinary skill in the art.
The reference numeral
1
,
FIG. 1
, generally indicates a mop head according to the present invention. The mop head
1
is made from a ribbon
2
of non-woven absorbent synthetic material folded lengthwise in multiple thicknesses. The material is that used in the manufacture of tea bags, food and industry machine filters, disposable uniforms, packaging, and the like. It is a waste material remaining from the manufacture of such items and are the trimmings or ends of rolls of such material. The material differs in resistance to abrasion, absorbency, longevity, abrasive qualities and other attributes. Because the ribbon can be put to various purposes as a substitute in mops, the qualities of the material are selected based upon the proposed use.
Referring to
FIG. 5
, the ribbon
2
is generally formed of a strip of the material which is folded or rolled longitudinally to provide overlapping layers of multiple thickness. The ribbon
2
may include an inner filling of scrap or other highly absorbent material
4
.
The ribbon
2
is processed through a mop winding machine which, as commonly used in the industry, has opposite arms
6
and
7
with respective traveling chains
8
and
9
. The arms
6
and
7
are typically supported at their rear ends only and are unsupported at the outlet ends so that a mop head wound thereon can be separated from the arms
6
and
7
without need for cutting. The chains
8
and
9
are rear-driven both by sprockets and travel forwardly along the outer edges of the arms
6
and
7
and return along the inner edges. A machine winding arm (not shown) winds the ribbon
2
around the spaced arms
6
and
7
to create a coiled wrapping
11
which is collapsed centrally to provide a center
12
of double thickness with top and bottom layers
13
and
14
. A center strip
16
of binder material extends longitudinally, as from a reel mounted in the mop making machine, and is positioned between the top and bottom layers
13
and
14
of the coiled wrapping
11
. The center strip
16
is of varying width, but preferably is several inches wide and is of much narrower width than that of the coiled wrapping
11
. The center strip
16
is preferably of non-woven absorbent synthetic material and is likewise a waste material from other manufacturing operations. The center strip
16
is sown in place by spaced rows of stitching
18
.
The coiled wrapping
11
with center strip
16
held in place by the stitching
18
is then severed as it comes off of the mop making machine arms
6
and
7
into lengths suitable for a mop head. The lengths may be relatively short such as 4-6″ when the mop head
1
is in the form of a wet mop or the lengths could be quite long when making a dust mop.
Certain forms of the invention have been illustrated and described herein. The invention is not to be limited thereto except insofar as set forth in the following claims.
Claims
- 1. A mop head comprising:a) a ribbon of non-woven absorbent synthetic material folded lengthwise in multiple thicknesses; b) said ribbon formed into a coiled wrapping collapsed centrally to provide opposite arms and a center of double thickness with top and bottom layers; and c) a center strip of binder material extending longitudinally and positioned between said top and bottom layers, and spaced rows of stitching securing said center strip to said top and bottom layers.
- 2. The mop head set forth in claim 1 wherein said ribbon is formed of several layers of wrapped material with an inner filling of absorbent material.
- 3. An absorbent pad for cleaning comprising:a) a ribbon of non-woven absorbent synthetic material folded lengthwise in multiple thickness; b) said ribbon formed into a coiled wrapping collapsed centrally to provide opposite arms and a center of double thickness with top and bottom layers; and c) a center strip of binder material extending longitudinally and positioned between said top and bottom layers, and spaced rows of stitching securing said center strip to said top and bottom layers.
