Models AVR 400 FLEXA | AVR 400 FLEXA TS

AVR 400 FLEXA is the ideal solution for high output applications. It is the top ring wrapping model by Pieri in the range, thanks to its outstanding features and unbeatable flexibility. Its many benefits include: Flexibility: with 15 different wrapping programmes, it adapts easily to any type of load, including products that are particularly unstable, crushable or oversized. Quality: AVR 400 FLEXA is equipped with a spool carriage for high pre-stretch percentages. The palletised product is perfectly wrapped, thanks to the tachometer generator built into the carriage. By dynamically adjusting the force exerted by the film on the load, both the shape and load remain intact. Exclusivity: one of AVR 400 FLEXA’s special features is ecoMATRIX, an exclusive film, clamping and tucking in device that is fitted as standard. By getting rid of loose unwanted film tails, ecoMATRIX provides the perfect solution for automatic warehouses and environments where there are low temperatures, dust and humidity. Standard configuration:

  • Motorised pre-stretch carriage (model MS-Pro) controlled by an inverter, with pre-stretch with fixed interchangeable ratios. The speed with which the film unwinds is controlled by a sensor which constantly adjusts the motor speed to ensure the pressure exerted on the film is the same over the whole perimeter of the load. The force exerted by the film on the product is electronically controlled and adjusted from the electrical control panel.
  • The ecoMATRIX clamping unit tucks the film tail into the last wrap through a sequence of electropneumatic movements. This sealing system can be used with any kind of film (micro perforated, macro-perforated, standard) and is particularly recommended in lines where there are automatic warehouses, LGVs and/or AGVs. This device, which does not cut or weld, emits no toxic fumes and is not affected by variations in ambient temperature.

  Also available the model AVR 400 FLEXA TS, fully automatic rotating ring wrapping machine with integrated top sheet applicator. The TS integrated device covers the top of the palletised load with a polyethylene film and is ideal for protecting it against water and dust.

Componenti opzionali

Optional components

  • Top press plate

    The top press plate exerts pressure on the palletised load to keep it stable during wrapping.
    Specially designed for wrapping machine loads, it is available in a pneumatic or electromechanical pantograph version.

  • Pallet lifter

    This device lifts the pallet during wrapping cycle, in this way the film covers both: the load and part or all of the wooden pallet.

  • Roping device

    As the name suggests, the roping system on the carriage reduces the width of the film until a rope is created, increasing load stability and securing the product to the pallet.

  • In-line top sheet applicator STF203

    This automatic device, positioned before the wrapping machine, covers the top of the palletised load with a polyethylene film, protecting it from dust. The film is cold cut by a pneumatically powered blade. The amount of film to place on the load is automatically calculated by a photocell, ensuring optimal consumption.

  • Electronic pre-stretch carriage with two motors – mod. AVS 240 PLUS

    Electronic reel carriage with variable pre-stretching driven by two motors controlled by an inverter.

    The pre-stretch percentage can be set from the electrical control panel (minimum 80% – maximum 350%) by adjusting the speeds of the motors installed on the carriage separately. This takes full advantage of the characteristics of the film, with a significant reduction in the amount used.

    It is also possible to set different pre-stretch percentages for each programme and wrapping cycle, ensuring maximum stability of the palletised load.
