WRS

Beam to beam precise warp passage.

Riavvolgitore subbi orditi ad alta velocità per filati di fibre discontinue o filamenti continui, utile per rimediare diversi problemi di orditura riavvolgendo l’ordito e recuperando lo stesso su di un nuovo subbio per la tessitura.

Il sistema è adatto per tutti i tipi di filati, naturali, sintetici e artificiali.

Due testate con motori AC controllano perfettamente la tensione della catena senza fluttuazioni o elementi di attrito.

La versione per filamenti è modificata e rinforzata per una frenata rapida, può essere impiegata anche come orditoio diretto fino a 600 m/min per i telai di indemagliabile.

TECHNICAL FEATURES:

• Machine structure:
  Modular system in line, main body in carbon steel (acid-proof painted). Mechanical and electrical components coming from primary European suppliers with their own worldwide sales and service networks.
• Machine motion and synchronization:
  Warp tension control with a positive system and speed synchronization with pneumatic high precision compensators controlled by means of vectorial AC digital drives, linked in master/slaves configuration on a ModBus network.
• Exclusive bi-directional (forward and reverse) running of the warp to minimize yarn waste and to facilitate resolving any operational problem.
• The inverters in the system are connected in a DCBus to regenerate energy and rapid response to the movements.

HMI machine control and supervision:

• 32 bits PLC, built-in supervision server for set-up, programming and diagnostic.
• HMI Web Panel touch screen panel allows complete on-board control for set-up, programming and diagnostics.
• Push buttons for all main basic functions and emergency control.
• Process controls available:

– Speed by manual input; super slow < 1 m/minute, preparation (set-up) and automatic working
– Warp tension and Pull
– Oil % application
– Diameter of yarn on beam at unwinder and winder with alarms for minimum settings.

Additional performances:
All process values are displayed in real time with possibility to modify them instantaneously, varying the recipe selected (pswd required).
