PROVISIONAL SPECIFICATION.
Improvements in Roping and Banding for Driving Machinery.
I JOHN ROWBOTTOм of 31 Hall Street Glossop in the County of Derby
Cotton Band Maker, do hereby declare the nature of this invention to be as
follows:
--
The object of this invention is to increase the durability of the roping or banding
employed for driving machinery and my invention is applicable to all such ropes or
bands made from two or more strands.
The said invention consists in lapping or wrapping each strand of which the rope
or band is made with a covering of suitable material.
For example in a seven strand cotton rope each strand is twisted in the usual
manner but a lapping of soft, loose and very slightly.twisted cotton is bound round
the same completely covering it and the seven strands so covered are twisted
together in the ordinary way.
It will be seen that in a strand-lapped rope made as above described all the
strain bearing parts are protected from wear against the pulleys or any other
external friction and the duration of the rope will consequently be greatly
increased.
I would remark in conclusion that I do not confine myself to any particular
material for covering the strands as it can be made of hemp flax, wool, silk, hide,
leather or any other suitable material. I find however that soft loose cotton as
above named is very suitable as, when in use, the soft covering fills up the recesses
formed by the twisting together of the strands and gives to the rope a very smooth
and even surface.
Dated this 14th day of December 1891.

COMPLETE SPECIFICATION.
Improvements in Roping and Banding for Driving Machinery.
I JOHN ROWBOTTOм of 31 Hall Street Glossop in the County of Derby,
Cotton Band Maker, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:―
The object of this invention is to increase the durability of the roping or banding
employed for driving machinery, and my invention is applicable to all such ropes or
bands as are made from two or more strands.
The said invention consists in lapping or wrapping each strand of which the rope
or band is made with a coiled covering of suitable material before twisting the same
together.
For example-in a seven strand cotton rope each separate strand is twisted in
the usual manner after which a lapping of soft, loose, and very slightly twisted
cotton is coiled or bound round the same, completely covering it, and the seven
strands, so covered are finally twisted together in the ordinary way.
I do not confine myself to any particular number of strands but I find that about
seven strands are suitable for driving ropes, three strands for rim bands for mules
and twiners, and two strands for spindle bands.
It will be found that in a strand-lapped rope made as above described all the
strain bearing parts are protected from wear against the pulleys, or any other

page_text: external friction, and the duration of the rope will consequently be greatly
increased.
I would remark in conclusion that I do not confine myself to any particular
material for covering the strands as it can be made of hemp, flax, wool, silk, hide,
leather or any other suitable material, or fabric.
I find however that soft loose cotton as above named is very suitable, as when
in use the soft covering fills up the recesses formed by the twisting together of the
strands, and gives to the rope a very smooth and even surface.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improvements in roping and banding for driving machinery consisting in
lapping or wrapping each strand with a covering of soft cotton or other suitable
material or fabric previously to twisting the same together to form the rope or band;
substantially as and for the purposes hereinbefore described.
