Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A method of locating a flexible sheet of magnetisable metal having a tacky upper layer thereon onto a planar magnetic support which includes the steps of: a. locating the planar magnetic support under a separating member, a portion of the planar magnetic support being exposed at the forward end thereof b. advancing the magnetisable metal member forward over the edge of the separating member to come into contact with the forward edge of the planar magnetic support, and c. advancing the planar magnetic support from beneath the separating member to draw the magnetisable metal member forward into further contact with the magnetic support.
Claim 2
Independent Claim
103 words
A method of locating a flexible sheet of magnetisable metal having a tacky upper layer thereon onto a planar magnetic support which includes the steps of: a. locating the planar magnetic support under a separating member, a portion of the planar magnetic support being exposed at the forward end thereof b. advancing the magnetisable metal member forward over the edge of the separating member to come into contact with the forward edge of the planar magnetic support, and c. advancing the planar magnetic support from beneath the separating member to draw the magnetisable metal member forward into further contact with the magnetic support.
Claim 3
Dependent Claim
14 words
A method as claimed in claim 1 in which the magnetisable metal is steel.
Claim 4
Dependent Claim
26 words
A method as claimed in claim 1 in which the magnetic support is a sheet of glass having a sheet of magnetic rubber on the surface.
Claim 5
Dependent Claim
14 words
A method as claimed in claim 1 in which the separating member is planar.
Claim 6
Dependent Claim
14 words
A method as claimed in claim 1 in which the separating member is non-magnetic.
Claim 7
Dependent Claim
16 words
A method as claimed in claim 1 in which the separating member is formed of brass.
Claim 8
Dependent Claim
114 words
In a method of manufacturing coated sheet steel, a method of locating a flexible sheet of magnetisable metal member having a tacky upper layer thereon onto a planar magnetic support, which includes the steps of: a. locating the planar magnetic support under a separating member, a portion of the planar magnetic support being exposed at the forward end thereof, b. advancing the sheet steel member forward over the edge of the planar separating member to come into contact with the forward end of the planar magnetic support, and c. advancing the planar magnetic support from beneath the planar separating member to draw the sheet member forward and into further contact with the magnetic support.
Claim 9
Dependent Claim
114 words
In a method of manufacturing coated sheet steel, a method of locating a flexible sheet of magnetisable metal member having a tacky upper layer thereon onto a planar magnetic support, which includes the steps of: a. locating the planar magnetic support under a separating member, a portion of the planar magnetic support being exposed at the forward end thereof, b. advancing the sheet steel member forward over the edge of the planar separating member to come into contact with the forward end of the planar magnetic support, and c. advancing the planar magnetic support from beneath the planar separating member to draw the sheet member forward and into further contact with the magnetic support.
