Abstract
Abstract A method of wiping hot dipped metal coated wire or strip, and an apparatus for performing the method, involving drawing the wire or strip upwardly from a bath of molten metal through a wiping bed located at the point of emergence from the bath, with an interference device being positioned adjacent the wire or strip below the surface of the molten bath such as to restrict the lamella flow of molten metal entrained by the moving wire or strip. The interference device wholly or partly surrounds the wire or strip and is located below the wiping bed, which bed in turn may be laterally confined or unconfined. The interference device may be of any convenient configuration such as in the form of a horizontally disposed flat plate provided with one or more slots, grooves or other apertures through which the wire or strip passes.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
90 words
A method of continuously wiping hot dipped metal coated wire or strip by withdrawing said wire or strip vertically upwards from a bath of molten metal through a wiping bed located at the point of emergence, characterised by the positioning of a static interference device adjacent the wire or strip below the surface of the molten metal bath and below and spaced from said wiping bed, said spacing not exceeding 50 mm, and such that it restricts the lamella flow of molten metal entrained by the moving wire or strip.
Claim 2
Independent Claim
90 words
A method of continuously wiping hot dipped metal coated wire or strip by withdrawing said wire or strip vertically upwards from a bath of molten metal through a wiping bed located at the point of emergence, characterised by the positioning of a static interference device adjacent the wire or strip below the surface of the molten metal bath and below and spaced from said wiping bed, said spacing not exceeding 50 mm, and such that it restricts the lamella flow of molten metal entrained by the moving wire or strip.
Claim 3
Dependent Claim
30 words
The method according to claim 1 wherein the clearance between the wire or strip and interference device is between 2 and 26 times the thickness of the desired ultimate coating.
Claim 4
Dependent Claim
35 words
The method according to claim 1, wherein the interference device is formed by a parallel sided, "V" shaped, circular, part circular or when viewed in plan and which may partly or wholly surround the wire.
Claim 5
Dependent Claim
15 words
The method according to claim 1, wherein the wiping bed is a gas wiping bed.
Claim 6
Dependent Claim
18 words
The method according to claim 1, wherein the wiping bed is a laterally unconfined bed of particulate material.
Claim 7
Dependent Claim
19 words
The method according to claim 5, wherein the unconfined bed of particulate material is a bed of oiled charcoal.
Claim 8
Independent Claim
73 words
An apparatus for continuously wiping hot dipped metal coated wire or strip, comprising a static interference device which wholly or partly surrounds the wire or strip and is arranged within the bath of molten coating metal and below and spaced from a wiping bed located at the point of emergence, said spacing not exceeding 50 mm, whereby said device restricts the lamella flow of molten metal entrained by the moving wire or strip.
Claim 9
Independent Claim
73 words
An apparatus for continuously wiping hot dipped metal coated wire or strip, comprising a static interference device which wholly or partly surrounds the wire or strip and is arranged within the bath of molten coating metal and below and spaced from a wiping bed located at the point of emergence, said spacing not exceeding 50 mm, whereby said device restricts the lamella flow of molten metal entrained by the moving wire or strip.
Claim 10
Dependent Claim
23 words
The apparatus according to claim 7 wherein the interference device is a flat plate having at least one parallel sided slot formed therethrough.
Claim 11
Dependent Claim
25 words
The apparatus of claim 7, wherein a plurality of parallel side slots are provided through said plate to accommodate a plurality of wires or strip.
Claim 12
Independent Claim
26 words
An apparatus according to claimm 8 which the plate is corrugated and the slot or slots are formed in the hills and/or valleys of the corrugations.
Claim 13
Dependent Claim
24 words
An apparatus according to claim 7 in which the interference device is a wire helix, refractory bead, or metallic cylinder which surrounds said wire.
Claim 14
Dependent Claim
38 words
An apparatus according to claim 11, wherein the wire helix, refractory bead, or metallic cylinder is held in place against a locating plate by the viscous forces associated with the liquid entrained by the running wire or strip.
Claim 15
Dependent Claim
24 words
An apparatus as claimed in claim 7, wherein the wiping bed is contained in a gas box into which a gas atmosphere is fed.
Claim 16
Dependent Claim
19 words
An apparatus as claimed in claim 7, wherein the wiping bed is a laterally unconfined bed of particulate material.
Claim 17
Dependent Claim
20 words
An apparatus as claimed in claim 14, wherein the unconfined bed of particulate material is a bed of oiled charcoal.
