Reflanging machine MRIFL

The explicit purpose of a spool reconditioning unit is to return B-type spools, commonly used for the winding of tire-cord, to their original dimensional tolerances through the restoration of the orthogonality between the flange and the barrel. This result is obtained by pressing the flanges by means of hydraulic heads, whose set-up can vary depending on the deformation degree of the flanges.

The reconditioning machine is not suitable for the reparation of damages/deformations on the barrel. The reconditioning cycle of the spools and their control post-pressing is performed in a completely automatic way. Once positioned on an appropriate chute, the spools are automatically driven to the holding cradle. The expulsion of the spool after the cycle is obtained by means of an automatic device which positions the spool on a chute equipped with control guides adjustable by the operator.

The spools needing a further repressing size after the reflanging process are blocked by the machine, automatically removed and stored in a tank where the operator can recover them for a possible further pressing cycle. The reflanging machines MRIFL are highly customizable and are available in the following versions:

Single or double reconditioning line

Depending on the required productivity, the reconditioning machines MRIFL can be supplied with single or double reconditioning line. A double-line reconditioning machine ensures a higher productivity and is able to recondition different models of spools at the same time. Each holding cradle can be equipped to recondition both B40-B60 or B80 spools. It is possible to change the set-up of the machine from B40-B60 to B80 (or vice versa) in a few working hours and without A.Appiani Srl staff intervention (an instruction manual is supplied ).

Partial or complete reconditioning cycle

The following reconditioning typologies are available:

- Simple (partial) reconditioning, which consists in the straightening of the spools with outward deformation of flanges

- Complete reconditioning, which consists in the straightening of the spools with outward and inward deformation of flanges - this last type of deformation is caused usually by falls or crushing.

Linear layout or chutes returning to the operator

Depending on the customer\'s needs, the MRIFL machines can be provided with a linear expulsion chute (linear MRIFL) or, alternatively, with an automatic system for the return of the spools to the operator (MRIFL with return to the operator). This \'return\' device drives the spools to the initial loading position so that even a single operator can unload them from the machine, with consequent benefits in terms of productivity. In the case of MRIFL with linear expulsion chute the presence of 2 operators is necessary, one for the loading of the spools on the machine and the other one for unloading and packaging.
