Improvements in the Finishing Treatment of Woven Driving'
Belting.
I, FRANK REDDAWAY, Managing Director of the Firm of F. Reddaway & Co.
Limited, of Cheltenham Street, Pendleton, in the County of Lancaster, Woven
Hose and Machine Belting Manufacturers, do hereby declare the nature of this
invention to be as follows:-
My said invention relates to the finishing treatment of woven driving belting,
and particularly to woven driving belting made wholly or partially from animal
fibre. Such helting before use receives generally several preservative coatings
of paint. As the oils and paints however if allowed to penetrate the animal
fibre would have an injurious effect upon the same, it is customary before applying
the paint to subject the belting to a preliminary treatment of size.
It has been found in practice that when the belting is used in damp or wet
situations or in hot moist climates that the moisture penetrates to the coating
of size, which is thereby dissolved allowing the paint easily to leave the belt.
The object of my invention is to obviate the foregoing disadvantage and this
I effect by first coating the belting with animal size and then passing it through
a bath of tannin which renders the size insoluble in water.
The belting is then coated with paint as heretofore.
Belting finished in accordance with my invention may be used in damp or
moist situations without the risk of the size being dissolved and the paint or other
matter with which the belt has been finished consequently adheres to the surface
of the belt.

drawings:-
My said invention relates to the finishing treatment of woven driving belting,
and particularly to woven driving belting made wholly or partially from animal
fibre. Such belting before use receives generally several preservative coatings
of paint. As the oils and paints however if allowed to penetrate the animal
fibre would have an injurious effect upon the same, it is customary before applying
the paint to subject the belting to a preliminary treatment of size.
It has been found in practice that when the belting is used in damp or wet
situations or in hot moist climates that the moisture penetrates to the coating
of size, which is thereby dissolved allowing the paint casily to leave the belt.
The object of my invention is to obviate the foregoing disadvantage and this
I effect by first coating the belting with animal size and then passing it through
a bath of tannin which renders the size insoluble in water.
The belting may be passed through the tannin bath in any convenient manner.
For instance in the accompanying diagram the belting a after having been
coated with animal size is led into a vat or tank b of any suitable size partially
filled with a solution of tannin in water. The strength of this solution is pre-
ferably about 10 per cent. The belting a before entering the tank b is conducted
over the carrying roller and from thence beneath the rollers ce disposed towards
the bottom of the vat b.
C
The belting is passed through the solution at a moderately slow speed so as to
allow the tannin to act upon the coating of animal size. As the belting leaves
the vat it is passed between the squeezing rollers d d which squeeze out the
superfluous tannin solution and the belting is then led away to be dried in any
convenient manner.
The belting is then coated with paint as heretofore.
Belting finished in accordance with my invention may be used in damp or
moist situations without the risk of tlie size being dissolved and the paint or other
matter with which the belt has been finished consequently adheres to the surface
of the belt.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1) In the finishing treatment of woven driving belting, subjecting the belting,
which has been previously treated with animal size, to the action of a solution of
fannin in water whereby the size is rendered insoluble in water, prior to the belt-
ing receiving the usual finishing coatings of paint for the purpose and sub-
stantially as described and shown.
2) The improved woven driving belting coated with animal size rendered in- 4
soluble in water by treatment with a solution of tannin in water prior to the
final coatings of paint substantially as described and shown.
