ABSTRACT OF THE DISCLOSURE
A pad wiping material for coated wire or strip and a method of forming such material. The material is a compressed, non-combustible,alumino silicate fibrous material which preferably includes asbestos, which has been compressed by the application of pressure in the range of 7 to 20 tonnes per square inch. The method of forming the pad wiping material includes compressing such a non-combustible alumino silicate fibrous material into a pad or disc by an application of pressure in the range of 7 to 20 tonnes per square inch.

Description
ll~S513 Thi8 invention ~elates to the wiplng of a metal coat-~ng applied to A wire or strip.
The invention h~s particular, although not exclusiYe app -5, lication to the wiping o~ A coating as wire or strip emerges~rom a bath of ~lolten ~etal such as zinc, or some other suit-able metal coating materi~l.
Up until this t~me, in the gal~anising of wire or coating of wire, the ~ire or str~p has ~een taken from the 10. bath at ~ shallow nngle to the horizontal and wiped with an as~estos pad or asbestos string.
In one case of asbestos string, the asbestos string is wound round the wire and the wire passed through a slot between a pair of fingers, so that the string is wedged 15. into the ~lot, thus w~ping the sur~ace of the wire or strip. In t~e case of pads, these have generally been formed by hand, by ~inding asbestos card into a pad or disc, the pad or disc then being placed in a suitable pad holder.
20, It is an object of this inYention to go someway towards providing an lmproved material for the wiping of coated wire or str~p, and to at least provide the public and manufacturers 25, ` qF
with a useful choice.
Other objects will become apparent from the following description.
According to an aspect of this invention, there is provided a wiping material for pad wiping of coated wire or strip, said material including alumino silicate fibrous material, compressed by an applied pressure in the range of 7 to 20 tonnes per square inch.
According to a further aspect of this invention, there is provided a method of forming a pad for pad wiping of coated wire or strip including compressing a non-combustible, alumino silicate fibrous material into a pad by an applied pressure in a range 7 to 20 tonnes per s~uare inch.
This invention will now be described by way of example onl~, and it should be appreciated that modifications and improvements may be made to the invention without departing from the scope or spirit thereof, as defined by the appended claims.
It has been found in experimentation, that a compressed non-combustible material has particular advantages in the wiping of wire or strip, which has been coated with a suitable coating such as zinc, or some other metal coating material during the processing of wire or strip.
In one form of the invention the compression is carried out by a press which consists of a piston moving within a tubular member or housing of a cross section corresponding substantially to that of the resulting pads.
.
11~5513 The applied pressure or pressure applied to the non-combustible material will vary depending upon the size of the wire to be wiped, and hence the ability of the pad to wrap around the wire on the other hand the ability of the pad to remain as an integral unit during wiping.
The compression and thus compacting of the non-combustible material causes the resultant pad or disc to remain as an integral unit during wiping.
For large diameter wires, the pads are preferably softer (that is to say compressed at a lower pressure) than would be the case for pads suitable for small diameter wires.
In the preferred form of the invention, a pad is formed of an alumino silicate fibrous material.
It has been found that by using an alumino silicate lS fibre material, which is compressed into a pad by an applied pressure in the range of about 7 to about 20 tonnes per square inch, there are a number of advantages.
By way of example the advantages are:
1. The use of alumino silicate fibre removes or at least reduces health hazards which might be present by using the asbestos material as has been used up until this time.

3. The use of alumino silicate fibre material as a pad wiping material has generally been found to give a longer and high pad life than other wiping materials (such as asbestos).
4. By using alumino silicate fibre material as a pad wiping material, it hac been found that a more even wipe is obtained over the wire or strip, than is generally obtained by using other materials (such as asbestos).
5. The use of alumino silicate fibre results in a tighter wipe about the wire or strip, and generally speaking results in a low coating thickness as compared with other materials.
The use of alumino silicate fibre is there-fore somewhat more economic than other materials.
As stated hereinbefore the non-combustible alumino fibrous material is compressed into a unit (a pad or disc) by pressure in the range of 7 to 20 tonnes per square inch, so as to result in a compressed pad or disc, which is able to be used for the wiping of coated wire or strip.
It should therefore be appreciated that improvements or modifications to this invetnion may be made without departing from the scope thereof, as defined by the appended claims.
