US Patent:

20010031344, Oct 18, 2001

Filed:

Apr 16, 2001

Appl. No.:

09/835606

Inventors:

Charles Nordeen - Saint Paul MN, US
Donald Knutson - Birchwood MN, US

International Classification:

B32B003/00
B32B027/14

US Classification:

428/195000, 428/202000

Abstract:

An image transfer process is provided for transferring an ink-jet image composite from an original receptor to a final receptor. The transfer process allows one to view an ink-jet image on a variety of substrates including mock-ups for packaging and other materials that would not be capable of receiving an image directly in an ink-jet printer.

8/010482

Inventors:

Duane A. Preszler - River Falls MN
Donald L. Knutson - White Bear Lake MN
Lawrence M. Lucking - Hugo MN

Assignee:

Minnesota Mining and Manufacturing Co. - Saint Paul MN

International Classification:

B41F 128
G03G 500

US Classification:

355211

Abstract:

A clamping and tensioning system for securing a sheet of photoconductor film to an outer circumferential surface of a carrier drum includes a clamp rod mounted to the carrier drum by first and second mounting blocks. The first and second mounting blocks include elongated slots that allow the clamp rod to rotate about its longitudinal axis and further permit linear radial movement of the clamp rod with respect to the carrier drum. The clamp rod includes mounting pins and spring tabs that engage leading and trailing edges of the photoconductor film. The leading and trailing edges of the photoconductor film are releasibly clamped to the clamp rod by a clamp bar. Leaf spring elements associated with the first and second mounting blocks bias the clamp rod radially inward to a first position wherein the photoconductor film extends loosely about the outer surface of the carrier drum. The photoconductor film is tensioned by rotating the clamp rod about its longitudinal axis which in turn winds the leading and trailing edges of the photoconductor film about the clamp rod. As the clamp rod is rotated, it moves radially outward with respect to the carrier drum along the elongated slots against the bias of the leaf spring elements.
