A method of supporting a ferromagnetic sheet having a tacky layer on its upper surface comprises locating the sheet on a support which comprises a sheet of glass having on its upper surface a layer of magnetic material.

Support

A continuous method of manufacturing a plurality of sheet material blanks each having a surface uniformly coated with a tacky layer comprises passing a long length of the sheet material through a first station in which tapes are applied to a surface of the sheet material transversely to the direction of movement of the sheet material and at longitudinally spaced-apart locations, at a second station applying a continuous layer of tacky material to the surface of the sheet material and over the tapes so that tapes mask portions of the surface, at a third station removing the tapes to leave transverse regions free of tacky material and then cutting the sheet material in the regions which are free of tacky material to thereby produce a plurality of sheet material blanks.

Cutting sheet material having tacky layer thereon

Locating a tacky polymer-coated steel sheet on a magnetic rubber-covered glass support by sliding the support out from under a shield and carrying the steel sheet with the magnetic support gradually to place the sheet on the support.
