Putsch®'s most popular compact edgebander, the EBP 420 offers increased panel workability in a footprint comparable to the EBP 320. The chassis is built to allow for two additional optional processes (edge/radius scraping, glue scraping and/or buffing unit) along with anti-adhesive and/or cleaning spray units. Moving at a speed of 7 meters per minute, the chain feed system has scratch-resistant rubber pads to carry the panel for consistent banding applicable work processes. The easy-to-adjust top bar includes a double row of rubber rollers to secure the panel.
The EBP 420 handles banding from .04 to 3 mm thick, and panels up to 45 mm in height. Coils are cut using an oscillatory cutting shear for uninterrupted edge feed. The machine has an automatic single-motor end trim unit with two 80 mm blades. The flush trim unit has 75 mm cutters (with disposable knives) that offer a straight / 2 mm radius / 15° bevel.
The intuitive PLC Control has thermostatic glue control with automatic stand-by and temperature display. The control permits the operator to engage or disable specific work operations while also providing immediate access to diagnostic messages and statistical data such as hours of operation and length of coil used. All operations can be viewed through the illuminated Plexiglas enclosure.
Unique to the compact class, the EBP 420 PM with Pre-Mill has twin 60 mm diamond cutters to eliminate chipping and deliver a perfect edge prior to glue application.
Another exclusive option is the EBP 420 PM-R with VR End Trim unit, capable of vertical rounding operation. Two processing modes, straight and radius, vertically mill off front and rear excess edges of panels when being processed.
