Automatic edger with two heads with four mobile blades and two splitting knives for high production of edged boards. Each head has been equipped with a 45 kW motor with soft start.
All movements are on slides and ball screws. Blades and splitting knives are accurately positioned using brushless motors. Internal blades are assembled at the end of the main shaft and positioned by moving the heads. Secondary blades are assembled on sleeves, which run along the main shaft, and can carry more than one blade.
Optional use of the two central blades only to give maximum widths for edged boards.

Infeed by transversal chain conveyer, with board turning device and laser triangulation photocells to trace the exact profile of the board as well as thickness and length.

Trimmer for cutting board to required lengths.

Board centering chain powered by brushless motors

Infeed chain with pressing rollers powered by 0-160 m/min hydraulic motor. Speed can be adjusted according to board thickness and current absorbed by the main motors.

11 kW hydraulic power pack

Outfeed pressing roller with pre-positioning.

System for board optimizing and managing the automatic cycle of the machine. Includes industrial PC with 15” touch screen linked by network cables to axis modules, PLC and reading system with photocells.

Automatic lubrication.

Stand control switchboard and operator keyboard.

Main electrical cabinet and separate cabinet for soft start of the two 45 kW motors.

MRA MSA Multiple Ripsaw

The machine is completely enclosed in compliance with current European safety regulations, thus becoming suitable for working both with manual loading and into a completely automatic line. The frame is composed of very thick structural tubes to guarantee high rigidity.
It is used to obtain boards and prisms from a large plank of various dimensions: the double shaft makes ripsawing extremely easy even for considerably thick, large hardwood planks.

Blade unit Each of the two blade shafts is made of special high-strength steel. The spacers are in aluminium and calibrated beforehand so as to ensure a perfect alignment of the blades. The bearings, provided with locking nuts, are constantly monitored by temperature sensors.

Motors The main motors, which comply with the unified size category, are appropriately fixed on rigid supports that guarantee a remarkable reduction of noise and vibration. In the event of excessive demand on the motors, the in-feed speed is reduced automatically.

Feeding belt The feeding belt is composed of a series of toothed bars which, thanks to their shape, allow a constant and continuous feeding of the large plank. It is driven by an electric motor with inverter, which thus allows the speed to be changed as needed.

Anti-kickback guards The machine is equipped with splinter guards and anti-kickback devices, which are always active during normal operation of the machine; in the event of routine maintenance work, however, they can easily be excluded using the control panel since they are operated by pneumatic cylinders.

Press The rollers that make up the press are operated by pneumatic cylinders with adjustable pressure. The structure that supports the rollers of the press is assembled on sturdy ball slides, which move on hardened prismatic guides.

Lubrication The machine is equipped with an automatic centralized lubrication system for the drive chains, the feeding belt and the various sliding points.

10.4” Touch-screen control panel The control panel is positioned near the machine on an articulated arm in order to make it more convenient for the operator to use. Some data, such as the position of the blade shafts, the cutting thickness and the in-feed speed, are continuously displayed and can be changed directly on the touch screen.

OPTIONS - Inclined roller in-feed unit with fence for the lateral support of the already edged planks - Centering in-feed unit for centering the large planks with respect to their central axis - In-feed unit with roller table having 4 rollers, 2 of which motorized by the multiple rip saw and 2 idle, and 2 pressure rollers with electropneumatic operation, used to make the feeding easier for machines with manual loading - Press with motorized rollers

MSA ONLY - Press for pieces with variable height: allows the ripsawing of large planks with a thickness difference within the range of 60 mm, spaced at least 500 mm from one another, - Roller table instead of the toothed feeding belt, particularly suited for highspeed feeding
