GORHAM, ME | The Montalvo Corp., an international specialist in industrial web control systems, has posted a presentation on its website to explain how to inexpensively upgrade Mark Andy 4120 presses for better productivity and reduced down time and waste.
The emphasis is on obtaining and controlling minimal tension on extensible materials from the full roll mode down to the core using the Mark Andy 4120 presses.
The presentation can be viewed at: www.montalvo.com/assets/presentations/upgrade-markandy-4120.swf.
President Ed Montalvo says the website shows the steps for brake replacement with the Montalvo C-Series dual disc brakes in situations where significant unwind friction and torque are occurring in the original brake installation.
According to Montalvo, the benefits to Mark Andy press users include being able to compete with the newer presses at a fraction of the cost of a new press, the ability to run lighter substrates, achieve faster line speeds, improve registration, increase production and minimizes waste, reduce setup time, increase machine flexibility to run a variety of products, and ease of installation.
Web tension in this upgrade is controlled by a Montalvo load cell-based S-3100 digital tension controller that replaces the existing dancer control system on the Mark Andy 2200. The system also uses a new Montalvo CD-104 brake assembly and a Montalvo TNT tension sensing roll replaces the existing idler roll.
