US Patent:

41726057, Oct 30, 1979

Filed:

May 16, 1977

Appl. No.:

5/797124

Inventors:

Bernhard J. Welsch - Cary IL
Nicholas P. Steiner - Chicago IL
Albert J. Kelley - Fox River Grove IL

Assignee:

Uarco Incorporated - Barrington IL

International Classification:

B41L 136

US Classification:

282 275

Abstract:

A ribbon, adapted for use on an impact printer, is provided wherein the ribbon is impregnated with a first substantially colorless substance which acts as a color-former when reacted with a second substantially colorless substance acting as a color-developer, present on a portion of a substrate. Upon the transfer of the color-former from the ribbon to the substrate by impact, a colored image will form on those areas of the substrate which are coated or impregnated with the color-developer. Images may thus be selectively transferred to an interior ply of a multi-ply business forms assembly by the conventional transfer methods without appearing on the exterior, impact receiving ply of such an assembly.

Filed:

Jan 8, 1990

Appl. No.:

7/462140

Inventors:

Bernhard J. Welsch - Waverly OH

International Classification:

B65H 318
B65G 5902

US Classification:

414796

Abstract:

In a paper processing machine, the method and apparatus of this invention apply an opposite electrostatic charge to stacks and reams of paper to eliminate the repelling force from like charges on both sides of the individual sheets of the stack or ream to thereby temporarily bond them together. With the sheets thus temporarily bonded, the stacks and reams of paper can be easily transported between work stations without undesirable sliding of the sheets.

Appl. No.:

6/819380

Inventors:

Bernhard J. Welsch - Cary IL

Assignee:

Uarco Incorporated - Barrington IL

International Classification:

B32B 306

US Classification:

428 41

Abstract:

A continuous business form including an elongated ply of label stock having one side coated with a pressure sensitive adhesive and of a desired width. An elongated ply of release liner stock of the same width is engaged with the adhesive in such a way that the plies are laterally offset. Consequently, a narrow longitudinal strip of adhesive unengaged with the release liner exists on the label stock ply. An elongated ply of record or message bearing stock is adhered to such edge of the label stock at the narrow longitudinal strip of adhesive.
