By the Slitting process, an entry mother coil of a certain width and weight is cut into several narrower and lighter daughter coils.
SALICO slitting lines cover the complete thickness range starting from the thinnest aluminium strip down to 0.1 mm, to the thickest carbon steel coils up to 20 mm.
High quality slitting requires very stiff and well designed slitter heads with zero axial gaps, absolute paralelism of the shafts on rotation, minimum shafts bending, combined with the right choice of tension device, able to provide high tension to the slits without any marks on the surfaces or on the edges of the processed material.
The slitting lines are probably the equipment which require the highest degree of operator attention and skill due to the fact that a large number of slits are handled at the same time for feeding and evacuation and also the different tools set ups must be prepared in advance by the operators in a very fast and accurate way. Therefore all the auxiliary items around the line which facilitate those operations reducing down times are of crucial importance for a properly designed slitting line. Special attention is paid to changing of the tools; easy, fast and ergonomic strip feeding systems and slits evacuation from the tension reel. Along the years, SALICO has developed intelligent solutions to tackle all these time consuming operations in an effective manner.
SALICO's target is to propose its customers with technical solutions specific to their needs, goals and resources. For this we can choose among a wide variety of solutions for each line functionality, in order to reach a combination that results in optimum yield of the investment, high quality products, low breakdown rates, ease of maintenance and most of all a safe and ergonomic operation.
Safe and ergonomic operation, also for the thickest and hardest strips.
