Title: The Innovative Contributions of Harold D. Welch

Introduction

Harold D. Welch is a notable inventor based in Phillips, Wisconsin, who has made significant contributions to the field of laminating technology. With a total of eight patents to his name, Welch has demonstrated a commitment to innovation and excellence in his work.

Latest Patents

One of his latest patents is a laminator for corrugated paperboard sheets. This invention is designed to apply pre-printed labels to a single face corrugated web, forming double face corrugated sheets. The laminator utilizes a control system that includes accurate leading and trailing edge detection of the labels. This ensures that the corrugated web is custom cut to match the label length, providing complete and uniform coverage of the glued flute tips. The labels are fed non-stop as a series of spaced sheets into a laminating nip, which joins the leading edge of the traveling single face corrugated web. A positioning nip upstream of the laminating nip varies the speed of the incoming sheets to accurately match the sheet leading edge to the web leading edge. The detection of the sheet trailing edge triggers the operation of the web cut-off knife, ensuring precise matching of the corresponding cut trailing edge.

Another significant patent by Welch involves a composite web material. This invention includes an industry-standard width composite paper web that comprises one layer of a plurality of narrow web portions derived from trim rolls of paper. These portions are laminated to a second carrier web of the selected standard width. In an alternate embodiment, the carrier web itself may consist of a plurality of narrow trim roll web portions. The web portions in each layer may be slightly spaced from one another, and the gaps between web portions in both layers must offset laterally to maintain the integrity of the composite web.
