Linee di produzione e imballaggio sottobobine

La linea parte da coil di grandi dimensioni e viene usata per produrre sottobobine (tipicamente di circa 1 – 3 ton), che vengono utilizzate in particolare nel settore delle costruzioni

La linea di produzione può anche produrre piccole bobine di lunghezza di ca. 30 - 150 m in zinco, rame, alluminio, acciaio preverniciato, di solito impiegate per realizzare particolari della copertura dei tetti nel settore civile.

Queste piccole bobine, vengono successivamente impilate e imballate a gruppi di 5/6 unità, ad asse verticale, su europallet.

Abbiamo sviluppato impianti per la produzione e imballaggio di sottobobine totalmente automatici, che riescono a produrre queste bobine con cadenza molto elevata, eseguendo la nastratura/reggiatura in automatico, l’imballaggio e posizionamento su pallet, compresa pesatura ed etichettatura.

Precision Re-rolling of Strip Steel Products

Precision re-rolling of strip steel products is becoming important across a host of industries.

Coiling Lines

When working the coil surface, the strip must usually be wound with steady tension between Uncoiler and Recoiler: Companies who clean, brush, grind or coat coil materials are the users of the pressmach Coiling Lines.
The design of the Uncoilers and Recoilers that are utilized is specially adapted to cope with high forces and deliver absolute precision.
Dependent the application, the Coiling Lines are expanded with Straighteners and Coil End Joining stations (Welders) as well as Trim Shears.

Coiling Line

Pressmach Coiling Lines have one core concern: to make sure, the strip is processed with precision and cleanness.

This is why we adapt the design of our Coiling Lines so we can use high tension and edge monitoring. Consequently, we run large drive forces – even for small cross-sections. The machine components are therefore built especially stiff and high-strength to absorb and convey all that power. To ensure an unobstructed processing or the commercial sale of the finished coil, it is necessary to rewind with highest layer-to-layer precision which we gain by the use of Coiling Line- special edge monitoring controls together with high precision traversing rails for motorized lateral adjustment of the Rewinder. That same precision is realized in the support of our customer – whether technical or coordinating.

Performance data:

  • up to 40 t coil weight and approx. 18 mm material thickness
  • max cross-section approx. 2200 x 8 mm
  • max winding speed approx. 100 m/min

Common Applications:

  • Feeding of coil stock into stamping or blanking presses with successive recoiling of processed material
  • Feeding of coil stock into different coating or surface-treating machines with successive recoiling of processed material
  • Coil-exchange from large master coil into several smaller coils, e.g. within steel service centers

Typical Compilation:

  • Pull-off or pay-off reel with loop control
  • Powered straightener to remove coil-set and flatten coil material
  • Roll-feed with servo control or set of pinch rollers to feed material
  • Strip-brake in front of recoiler to ensure tight recoiling 
  • Powered Recoiler with loop control, to pick up processed coil material from loop in front of strip brake
  • Peripheral guarding with electric interlock

Additions & Extensions:

  • Shear to cut off coil material for desired coil sizes
  • Coil cars for pull-off / pay-off reel and recoiler
  • Various hydraulic and motorized features and components to enhance capacities and level of automation
