ABSTRACT:
Magnetic devices are described which include a sheet of magnetic material having a relieved groove/ridge configuration, all the grooves and ridges being straight and parallel, and evenly spaced apart. Such devices can form part of apparatus for use in connection with a dry transfer sheet in assisting setting out a correctly spaced and aligned legend on a desired receptor surface. The apparatus can comprise a base member which, e.g. may be attachable to a designed receptor surface and a sheet-holder member. The sheet-holder member can consist of a bar to which a sheet of dry transfer material may be attached. One side of the bar of the sheet-holder member has a rib which may engage in the base member in one of the parallel grooves therein. The lateral spacing of the parallel grooves and the vertical spacing of lines of letters on the dry transfer sheet correspond to ensure accurate horizontal alignment of letters transferred from different rows on the transfer sheet to the final receptor. Convenient transfer sheet layouts are described.
