Introduction

David R Wilkins is a notable inventor based in Wistaston, GB. He has made significant contributions to the field of printing technology, holding a total of three patents. His work focuses on enhancing the efficiency and accuracy of printing processes.

Latest Patents

One of his latest patents is the "Printing Wheel Setting and Aligning Apparatus." This invention comprises printing wheels on a common shaft, which together define a printing line over a hammer. Each printing wheel is rotated by a respective stepping motor through a respective setting wheel. An aligner bar is inserted into notches in the wheels prior to printing to verify the alignment of the characters in the printing position. The stepping motors are bi-directional and take the shortest path from a preceding printing position to the next. The pulsing frequency may be ramped to achieve a higher stepping rate during the intermediate portion of each printing wheel movement.

Another significant patent is "Printing in Register on Sheets." This invention addresses the high-speed printing of a line of text on a sheet with very accurate registration to an edge or another feature on the sheet. The sheet is fed without pre-registration onto a track that passes the printing station. A detector adjacent to the track senses the arrival of the edge or another feature of the sheet. A printing control means, responsive to the detector signal, initiates the firing of the printing hammer when the print line reaches the printing station, thus achieving a registered operation without stopping the sheet.
