Comerio Ercole advances technologies for calendering, winding

Busto Arsizio, Italy – Comerio Ercole is working to enhance the performance of its equipment across a series of metrics, Italian rubber machinery maker said in its latest monthly newsletter.

The programme has included the recent completion of testing on a special calendering plant for rubber sheets based on a ‘miniduplex’ configuration.

The four-roll set-up is capable of providing a rubber thickness of only 0.075 mm for each rubber sheet, according to the company’s report issued 25 Nov.

Employing a ‘hydroplus’ configuration, the system makes it “possible to easily obtain productions of very thin thicknesses,” the machinery maker stated.

Another development is the ‘shuttle CE’ winding system: a configuration for automatic roll change at the set length, without slowing down the calender and without operator intervention.

The ‘shuttle CE’ winding section consists of two identical stations on a mobile platform, the machinery manufacturer explains.

While the station in operation is located under the cross-cutting unit, the other station is located off the axis of the calendering line – on the opposite side of the station in operation.

Roller-changes for both the product and the liner can be done on either side of the calendering line in the offline position, according to Comerio Ercole.

Loading and unloading can be done with a dedicated crane system or a factory-integrated automatic system, the company also noted.
