COMPACT UNCOILING, FEEDING AND STRAIGHTENING UNIT Mod. A.R.C.

  • Compact uncoiling, feeding and straightening unit mod. a.r.c.


The particularly compact line is made up of two main units: the feeder-straightener and the uncoiler. Both machines rest on an arc-welded connecting base. The AR type feeder-straightener (mod. AR Feed and Straightening unit features) is connected to the press by means of robust sliding guides which allow the sheet metal to be vertically aligned to the die, at the same time as maintaining its horizontal rigidity. The uncoiler is made up of a robust arc-welded steel structure which supports the four spoked, hydraulic expanding, self-centring mandrel. The mandrel is driven by a hydraulic motor which is coupled to a pneumatic disc brake. The uncoiler can be equipped with a hydraulic snubber roll with hydraulic motorised wheel and the feeder-straightener can be fitted with a oil-pressure telescopic intake with upper counter-roller. Sheet metal of greater thickness can be fed into the die with these two alternatives, without the assistance on the part of the operator, who follows the entire tooling operation from the electrical panel. The sheet metal can be moved and centred inside the die by the operator by means of a portable push-button panel which is particularly useful when working with very large presses. The entire line is cordoned off on two sides by barriers and optoelectronic barriers can be installed on the operators side on request. Any AR feeder model can be matched to the width and the capacity of the reel thereby obtaining various customised combinations.
