The Eastside Machine Company EM 6/8/10 jobsite roll-formers are built upon a heavy-duty steel frame for structural stability and forming consistency. Industrial nitro-carburized (QPQ) steel rollers are used in all Eastside Machine Co. products. Nitrocarburizing rollers allow for improved wear and lubricity, as well as strength and corrosion resistance. Our proprietary embossing rollers, which apply an authentic and natural woodgrain texture to steel or aluminum coil, are artfully designed for pattern beauty and panel rigidity.

An extendable cutting table gives you the flexibility to make your cuts more precise. Our portable siding machines operate with a 1.5 HP, 115 Volt, 20 Amp electric motor and have variable speed frequency drive. This allows our seamless siding machines an infinitely adjustable forming speed from 1' to 60', giving you the ability to produce more than other machines on the market. Our siding machines also come standard with an extendable remote switch with forward and reverse, allowing machine operation from outside the trailer.

Eastside Machine Co. knows the importance of making loading and unloading coils as simple and safe as possible. With siding machines from Eastside Machine Co., your installers/operators can load and unload coils without using a forklift, like most portable siding machines. An accessory coil loading system can be mounted to your enclosed siding trailer and can effortlessly lift coils up to 2,500# in a matter of minutes using a 110 Volt winch. Safety is very important at Eastside Machine Co., and it is something we take very seriously. All our siding machines are equipped with an emergency shut-off button and a spool brake to control the coil when operating the machine.

Like all machines from Eastside Machine Co., our portable seamless siding machines come with operational training, technical support, and a five-year warranty.

Guillotine Cutter

Eastside Machine Co. offers a multi-profile guillotine cutter standard on every seamless siding machine. Industrial nitrocarburized steel blade gives a very desirable, clean cut. The durability of the blade allows it to keep its sharp cutting edge, which minimizes maintenance; think of an Eastside Machine Co. guillotine cutter as comparable to the Ginsu knife's role in a kitchen.

Unidrive System
Unidrive System

Unidrive is an AC Drive and Controller system with integrated Programmable Logic Control (PLC), and comes standard on all 2016 and newer EM 6/8/10 Combo Seamless Siding Machines. The Unidrive converts single phase 110 Volt to 3-phase 220 Volt without the need of a transformer, resulting in a much more efficient use of power. Unidrive benefits include: less power used, fewer circuit breaker, and GFI outlet problems and the ability to add the ATM system to your Eastside Machine Co. portable siding machine.

All siding machines come equipped with Unidrive. Benefits include more power efficiency, fewer tripped Circuit Breaker, no transformer, and the ability to add Auto Tape Measure (ATM) System.

Have an older Eastside Machine Co. EM 6/8/10 Combo Seamless Siding Machine with Softstart or Phase II Electrical? Unidrive can easily be added to 2015 and earlier models. Just call Customer Service at (800) 234-7834 to learn more.

Auto Tape Measure (ATM) System (Optional)

The Auto Tape Measure (ATM) System will measure the panel length as it is formed. Cut lengths can be set in the ATM without the need of measuring. Batch any number of same-length panels to increase efficiency, all while adding convenience and accuracy on the jobsite. ATM is also a great way to track the total number of feet used (like an odometer in a car) or the number of feet used during a single job. ATM is an upgrade that can be added to any Eastside Machine Co. portable siding machine with the Unidrive system. To learn more about the benefits of ATM and how it can help your install teams be safer and more efficient both in accuracy and speed, call Customer Service at (800) 234-7834.
