US Patent:

46743804, Jun 23, 1987

Filed:

Jan 29, 1986

Appl. No.:

6/823949

Inventors:

David Hecht - New York NY
Steven F. Schultz - East Hampton NY

International Classification:

B26D 726
B26D 103

US Classification:

834252

Abstract:

An apparatus for longitudinally cutting a web into a plurality of ribbons has a plurality of blade holders mounted so that the relative spacing as well as the overall lateral position of the blades can be shifted in response to growth, shrinkage, and lateral shifting of webs, while maintaining the blades perpendicular to the direction of travel of the web. The blades are held in holders having the ends interconnected by a parallelogram linkage and clamped to a rigid bar and a flexible extensible rod.

Appl. No.:

8/168300

Inventors:

Vittorio Castelli - Yorktown Heights NY
David L. Hecht - Palo Alto CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B41J 2385
G03G 2100

US Classification:

347133

Abstract:

A method of achieving optimum optical contrast for detecting registration marks in a multicolor electrophotographic printing machine. The reflectivity of the image carrying member which is usually an intermediate transfer belt is determined. The reflectivity of each of the toners is then determined. If one of the toners has a contrasting reflectivity, while the remaining toners do not contrast then a uniform field of the contrasting toner is imaged and developed and the registration marks for the other toner colors are then developed on top of the uniform field. A void in the field in the shape of the other toner marks is used as the registration mark for the contrasting toner. If all of the toners have a contrasting reflectivity with the belt, the registration marks are imaged and developed directly on the belt.

Appl. No.:

8/764594

Inventors:

David Hecht - Greenwich CT

International Classification:

A41H 4300

US Classification:

223 46

Abstract:

A simplified method and an apparatus for making bows comprises a base into which movable rods and fixed hoops are perpendicularly set whereupon a bow or other decoration may be made by winding ribbon or the like around the rods while retaining said ribbon between the hoops and then tying off the ribbon into a bow through the application of a tying means banded transversely and securely around the wound ribbon, whereupon said bow is removed from device and shaped into an aesthetically pleasing bow.

US Patent:

Filed:

Jan 28, 1987

Appl. No.:

7/007771

Inventors:

David Hecht - New York NY

International Classification:

A41H 4300
D04D 710

US Classification:

223 46

Abstract:

A method and apparatus for making bows comprises a tie member wrapping machine which wraps a tie member around a run of ribbon and twists it at the free ends. In order to dispose the tie at the center of the run of ribbon, a jig is mounted on the head of the wrapping machine to position the ribbon at the slot of the machine and to center the ribbon relative to the slot. The jig includes diverging rods around which the ribbon is wrapped. As the ribbon is moved rearwardly into the slot, a slack develops in the ribbon to permit a tight cinching of the central portion by the tie member.
