As the fiscal year starts for many companies, so too does a rush of machine upgrade projects. This is a subject that is full of both big opportunities as well as big risks. I have written a book on the subject of buying/selling web machinery. https://www.destechpub.com/product/web-machine-buying-guide/
Also, as a previous machine designer myself, I weave many best practices for web machine design into my Web Handling and Converting and Winding courses that have been taken by about 5,000 students, either in plant, at a public venue or as video-on-demand. https://www.aimcal.org/web-handling--converting.html
Finally, for those looking just for a few 5-minute executive summaries of this extensive topic, I offer a short series of common design questions about web machinery. Enjoy.
