Maggi Steff 3 roll variable speed feeder describes a stock feeder with three rollers and an adjustable feed rate from 9 to 59 feet per minute, so you can match feed speed to the cut for smoother results or higher throughput. The feeder uses variable speed driven by a belt on a conical aluminum pulley, which lets the operator set the speed within the range while keeping power transfer consistent under load. A turn knob controls the required speed without the need to change the position of the gears, so changing speed is a quick front-of-machine adjustment instead of a time-consuming mechanical changeover. A min - max plate indicates the rotation direction to obtain the required speed, giving a visual reference that helps set rotation correctly for the desired feed rate. The unit weight of 147 lb helps the feeder stay steady during operation, which supports consistent feeding on machinery running at typical shop cutting speeds.
The Maggi Steff 3 3-roll variable speed feeder is designed for use with machinery that may be configured as either 1-phase or 3-phase, and the motor output reflects that difference in supply. On a 1-PH machine the feeder uses a 0.75 HP motor, giving power appropriate to that supply type for feeding stock at the 9 to 59 FPM range. On a 3-PH machine the feeder uses a 1 HP motor, which provides additional power capacity to maintain feed speed under typical load across the same range. The turn knob for the required speed is used together with the belt on the conical aluminum pulley, so the operator can adjust speed in a controlled manner. The min - max plate indicating rotation direction ties into that system, guiding the operator on which way to rotate for the desired portion of the speed range.
The SAP description VARIOSTEFF 3 3RL VAR SPD FEEDER 440V 3PH identifies this as a variable speed stock feeder configured for 440V 3-phase use, which aligns with machinery in shops wired with that service. The category listing as Machinery and Stock Feeders places this unit in the role of feeding workpieces into woodworking machines such as shapers or similar equipment, where consistent feed is important for repeatable cuts. The 4-3/4 inch roller diameter and 2-1/4 inch roller width dimensions define the contact profile of the three rollers, which supports steady grip on typical board widths used in many cabinet and millwork operations. The weight of 147 lb means the feeder assembly has substantial mass, which helps resist movement from vibration or minor bumps during normal use once the stand is positioned. The variable speed range from 9 to 59 FPM lets the same feeder be used across different operations on compatible machines, from lower speed passes for more delicate cuts to higher speed runs for general stock removal.
The speed adjustment system using a belt on a conical aluminum pulley allows the feeder speed to be varied within the 9 to 59 FPM range while keeping a continuous belt connection, which supports smooth power transfer as the speed is changed. The turn knob for the required speed ties directly to this system, giving a simple control that changes speed without the need to change the position of the gears, so operators can respond quickly when moving from one cut to another on the same machine. The min - max plate that indicates rotation direction for the required speed visually links knob rotation to speed change, which helps the operator move toward either the lower or higher end of the range without trial and error. The distinction between a 0.75 HP motor on a 1-PH machine and a 1 HP motor on a 3-PH machine shows how the feeder output is matched to the electrical supply, which supports maintaining feed forces appropriate to the machine configuration in typical woodworking use. Across these elements, the Maggi and Steff branding identifies the manufacturer pairing behind the feeder and its stand, which situates this unit within a recognized family of stock feeders used on woodworking machinery.
The product is a Maggi Steff 3 3-roll variable speed stock feeder with stand, used to feed material into woodworking machinery at controlled speeds.
The stock feeder offers a variable speed range from 9 to 59 feet per minute, letting operators select slower or faster feed to suit the cutting operation.
The feeder speed is adjusted using a turn knob connected to a belt on a conical aluminum pulley, changing speed without repositioning gears.
The min - max plate indicates the rotation direction needed on the control to reach lower or higher speeds within the 9 to 59 FPM range.
The stock feeder has rollers with a diameter of 4-3/4 inches and a width of 2-1/4 inches, setting the contact profile on the workpiece.
On a 1-phase machine the feeder uses a 0.75 HP motor, while on a 3-phase machine it uses a 1 HP motor, matching power to the supply.
The Maggi Steff 3 3-roll variable speed feeder with stand combines three rollers, a 9 to 59 FPM speed range, and a belt driven conical aluminum pulley system to control feed. The 4-3/4 inch diameter and 2-1/4 inch width rollers work with the 147 lb overall weight to support steady contact as stock passes under the feeder. For shops running 1-phase or 3-phase machines, the matched 0.75 HP or 1 HP motor ratings tie the feeder into the available supply while keeping the same variable speed functionality. When a project calls for controlled, powered feeding on woodworking machinery, this configuration from Maggi and Steff offers a defined set of capacities and adjustments for that role.
