A servo-driven horizontal trim press that reportedly increases flexibility in part handling and permits fully automated packaging was introduced at the recent NPE show by Brown Machine LLC, Beaverton, Mich. The LS-Model press automatically slows down for a controlled long ejection into product-handling systems. It is available for sheet widths from 33 in. to 74 in. Brown’s usual 32-in.-diam. flywheels are replaced by 22-in.-diam. drive sheaves, which reduce inertia by more than 80%. This allows the drive to efficiently slow the press for the ejection cycle and then quickly ramp up to high speed. Platen movement is precisely guided with eight linear bearings on the moving platen, and a new counterbalance system provides stable motion at high speeds. In addition, the window for side loading of trim tools is expanded from 25 in to 37 in. The larger opening offers side-load capabilities for tools for drink lids, berry boxes, and food containers that have pre-punched straw slots, sip holes, vent slots, or drain holes. The moving platen is also taller to support these progressive trim tools.
