Abstract
An embossing roll is formed by a process which includes molding a seamless embossing roll within a seamless sleeve. The sleeve has indicia disposed about the inner circumference and which is then reverse molded into the roll.
Claims11
A process for forming a decorating cylinder having indicia thereon which is desired to be embossed onto a film, said method comprising:
- (i) providing a seamless cylindrical member;
- (ii) providing a seamless, outer exposed surface of an imprintable material over said cylindrical member;
- (iii) modeling first indicia into said outer surface of said imprintable material;
- (iv) forming a continuous seamless sleeve about said cylindrical member, said sleeve having reversed indicia in its internal surface resulting from the molding of the sleeve against the outer surface of said cylinder;
- (v) molding a decorating cylinder within and against the inner surface of said sleeve, said cylinder having indicia substantially corresponding to said first indicia.
A process for forming a decorating cylinder having indicia which is to be embossed onto a film comprising:
- (i) imprinting at least a portion of the external circumference of a seamless cylindrical sleeve member to provide a recessed pattern;
- (ii) turning said sleeve inside-out so as to have said recessed pattern disposed on the internal portion of said sleeve;
- (iii) molding a decorating cylinder within said turned sleeve, said cylinder containing said recessed pattern in reversed form.
A method for producing a seamless embossing roll comprising:
- forming a pattern on the external surface of a modelable, hardenable, seamless sleeve member, hardening said sleeve member;
- turning said sleeve inside-out;
- dispensing a moldable, hardenable material into the inner portion of said turned inside-out sleeve and allowing said material to mold against the internal surface of said turned inside-out sleeve;
- and hardening said material so as to form a seamless cylindrical member having a reversal of said pattern on the external surface of said member.
A process for forming a decorating cylinder having indicia thereon which is desired o be embossed onto a film, said method comprising:
- (i) providing a seamless cylindrical member having a seamless, outer exposed surface of a heat hardenable material;
- (ii) modeling first indicia into said outer surface of said imprintable material;
- (iii) heating said material to harden same;
- (iv) forming a continuous seamless sleeve about said cylindrical member, said sleeve having reversed indicia in its internal surface resulting from the molding of the sleeve against the outer surface of said cylinder;
- (v) molding a decorating cylinder within and against the inner surface of said sleeve, said cylinder having indicia substantially corresponding to said first indicia.
