WOA 50th ANNIVERSARY -- An Industry Time Line

1938—American Type Founders (ATF) acquires the Webendorfer-Willis Co., therefore inheriting the web engineering from that enterprise. Around 1945, ATF starts to manufacture web offset presses designed to be used for printing catalogs, newspapers, magazines, telephone books and encyclopedias. In time, added features are available, including sheeters, full-width double imprinters, high-speed folders, two jaw cylinders for single and double parallel folds, choppers for right-angle folds, full-width cross-perforation and slot-type vertical perforation, and ribbon folders able to interleave color pages with black-and-white pages anywhere in the signature.
