De bobine en sous-bobine


Lignes de production et conditionnement de sous-bobines

Lignes de production et conditionnement de sous-bobines

La ligne part de bobines (coils) de grandes dimensions et est utilisée pour produire des sous-bobines (typiquement environ 1 – 2 tonnes), qui sont utilisées principalement dans le secteur de la construction

La ligne est également en mesure de produire de bobineaux d’une longueur d’environ 30 m en zinc, cuivre, aluminium, acier pré-peint, employées surtout pour réaliser des éléments de couverture des toits des maisons.

Ces bobineaux, peuvent ensuite empilées et conditionnées en groupes de 5/6 unités, à axe verticale, sur des euro palettes prêts pour le transport.

Nous avons développé des installations de  production et le conditionnement de bobineaux  totalement automatiques, en mesure de produire ces bobines avec une cadence élevée (environ 1 bobine toutes les 2 min), en effectuant le banderolage/cerclage en mode automatique ainsi que le conditionnement et le positionnement sur palette, y compris le pesage et l’étiquetage.

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
