Ammonia Printing Machine Futura Single Tube APM F1

Present day digital printing machines may have taken over and replaced the significantly older blueprinting technology, but Ammonia Printing Machine Futura F1 (APM-F1) is still loved by and is the first preference of even some of the most advanced small and medium size drawing offices, drafting stations and R&D tool rooms. It is not just because of the elegant solid state circuitry that controls APM-F1 or the compact structure that beautifully houses the components. It is because of the simple and classic design of Ammonia Printing Machine Futura - F1 that has earned a niche in the drawing office equipment industry 35 years ago, since its inception, and is still at par with any modern printing machine in terms of performance and utility.

Construction:
The machine body is manufactured using prime quality CRCA steel sheets for maximum durability and longevity. A rigid structure combined with a space-saving compact design gives a professional look to the product. 

Exposure:
APM-F1 boasts a Phillips Holland make 140 Watt Super Actinic light source and a rotating glass cylinder for exposure. The glass cylinder is driven by an endless conveyor belt which allows users to feed an infinite length of paper and a maximum feed width of 120cm (3 Feet).

Feed Speed Variation:
To ensure a smooth, vibration-free and hassle-free operation, APM-F1 is driven not by friction drives or change gears, but by a 24V variable supply DC motor. Depending upon the details and the quality of the trace required, the exposure time can be very easily adjusted by controlling the speed of the DC motor, with the help of a fine potentiometer. APM-F1 features a maximum feed speed of 2 meters/minutes.

Control Panel:
APM-F1 is fitted with a panel for controlling various operations such as feed speed, feed direction, light on-off and mains power on-off. The control panel is backed by a robust circuit design to ensure long, maintenance-free operation and does not require any cooling device.

Development:
A separate leak-proof static developing chamber is provided along with the machine. The developing chamber is essentially a sheet-metal enclosure with a door fitted with a ball catch latch for easy and fast handling. Suitable provisions for keeping the ammonia roll below the feed platform in a closed roll chamber and to cut the paper on feed platform are also provided.

Power Supply:
Power consumption is nearly 200W and the machine requires a 230V 50 Hertz Single Phase AC Supply. Ammonia printing machine APM-F1 can be operated with any 5 Ampere 3 Pin socket.

Operation:
This machine is very easy to operate. The tracing and ammonia paper are first fed in to the machine over the feed table. They can be adjusted for exact printing speed and mis-feeding of materials can be stopped. The exposed ammonia/diazo paper is then placed in the vertical developing chamber to get the copy.
