Abstract:
Printing facility for the manipulation of a plurality of sleeve assemblies (52) each composed by a printing sleeve (50) having a cylindrical internal surface (61) with a diameter larger than the diameter of a printing shaft (12) and an independent tubular cylindrical intermediate sleeve (51) inserted into the cylindrical printing sleeve (50), said printing sleeve comprising a printing machine (10) comprising cylindrical printing shafts (12), and a robotic unit (20) comprising a sleeves handling device (21), the facility further comprising a first storage (30) for store a plurality of printing sleeves (50), which include retaining elements (31) for the immobilization of the stored printing sleeves (50) in geometrical interference with the printing cylindrical external surface (60) and/or with at least one of the annular faces (62) of the printing sleeves (50).
Abstract:
A stamp structure includes a stamp frame having a plate part. The plate part includes a plurality of holes. The plurality of holes are configured to facilitate the adsorption of an object to the plate part during a transfer of the object from a donor substrate to a target substrate.
Abstract:
A printing plate unit automatic mounting apparatus 81 includes: a pressing member 96 inserted from a pressing member insertion opening 33 and pressing an inner slider 36 against a biasing force applied by a printing plate coupling member biasing apparatus 35, a retaining means 94 configured to retain and release the printing plate unit 1 by retaining and releasing a projecting portion 11a provided on the printing plate unit 1 and configured to serve as a gripping portion; and a drive apparatus 92 configured to move the retaining means 94 in an axial direction of a plate drive shaft.
Abstract:
A seamless, embossed or cast substrate is formed using a seamless sleeve having a seamless surface relief formed thereon and configured to slide over an cylindrical base in an embossing or casting assembly. The substrate is a flat web, foil, or film of, for example, paper, polyester, polypropylene, metal or other elongated flat material. The surface relief can be applied through interfering ablation, non-interfering ablation, ink jet printing, or other techniques wherein a seamless surface relief is formed onto the seamless sleeve. A method of making a seamless, embossed or cast substrate includes expanding a diameter of a seamless sleeve having a seamless surface relief formed thereon, sliding the expanded seamless sleeve onto a cylindrical base, allowing the diameter of the seamless sleeve to contract around the cylindrical base, and conveying a substrate through the embossing or casting assembly and embossing or casting the seamless surface relief into the substrate.
