Abstract
Abstract A sheet of malleable material such as photographic film or paper is placed over a projecting mark on an anvil, such as a number, and an ultrasonically vibrating horn is placed against the opposite side of the sheet. The sheet can be a continuously moving web, and the anvil can be a cylinder which rotates as the web passes in contact therewith, with the mark being periodically brought into register with the horn. Indexing mechanism can be provided to change the mark with each revolution of the anvil.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
195 words
A method for embossing indicia into a continuously movable web of malleable heat deformable material such as photographic paper or film comprising: providing a cylindrical anvil rotatable around a fixed axis and having indicia projecting from the surface of the anvil; guiding a web of malleable heat deformable material around and into continuous engagement with a portion of the anvil surface; simultaneously continuously transporting the web and rotating said anvil with said web and said anvil surface in contact and moving at substantially the same speed to successively bring said indicia into contact with said web and then into an embossing position in engagement with one side of the web once each revolution of said anvil then removing said indicia from contact with said web after passing said embossing position; and applying ultrasonically vibrating pressure impulses by an ultrasonic vibrating device directly to the side of the web opposite the side engaged by said anvil at the embossing position for applying heat and pressure to the web for embossing said indicia into the web when said indicia and said vibrating device are in register at said embossing position and while said web is being transported.
Claim 2
Independent Claim
195 words
A method for embossing indicia into a continuously movable web of malleable heat deformable material such as photographic paper or film comprising: providing a cylindrical anvil rotatable around a fixed axis and having indicia projecting from the surface of the anvil; guiding a web of malleable heat deformable material around and into continuous engagement with a portion of the anvil surface; simultaneously continuously transporting the web and rotating said anvil with said web and said anvil surface in contact and moving at substantially the same speed to successively bring said indicia into contact with said web and then into an embossing position in engagement with one side of the web once each revolution of said anvil then removing said indicia from contact with said web after passing said embossing position; and applying ultrasonically vibrating pressure impulses by an ultrasonic vibrating device directly to the side of the web opposite the side engaged by said anvil at the embossing position for applying heat and pressure to the web for embossing said indicia into the web when said indicia and said vibrating device are in register at said embossing position and while said web is being transported.
Claim 3
Dependent Claim
192 words
Apparatus for embossing indicia into a web of malleable material such as photographic paper or film comprising, in combination: a rotatable cylindrical anvil having a surface and rotatable past an embossing position; indicia on said anvil projecting from said surface a predetermined distance; means for guiding a web of malleable material into continuous engagement with said anvil surface, said engagement beginning prior to passing said embossing position and ending after said embossing position has been passed; means for simultaneously transporting said web and rotating said anvil with said web and said anvil surface in contact and moving at substantially the same speed; and an ultrasonic vibratory device adapted to be ultrasonically vibrated and having an end face positioned at said embossing position adjacent to and spaced from said anvil a distance substantially equal to the combined distance of said predetermined distance and the thickness of the malleable material, said end face of said vibratory device being adapted when vibrated to directly apply heat and pressure to the material for embossing said indicia into the material while said material is being transported and when said indicia is in register with said end face.
Claim 4
Dependent Claim
