MQA / MRA / MSA TWO-SPINDLE 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 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.

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.

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

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 ripsaw 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.
