High performance slitting lines

High performance and flexibility are the hallmark of GEIT slitting lines. We can supply simple lines for low production rates or more sophisticated lines with coil weights up to 45 tons and speeds up to 400 m/min. Thus Stam is able to fulfill the requirements of both small companies and big service centers.

The slitting line is composed of:
decoiling from coils, trimming, slitting and recoiling the coils.
specifically:
– uncoiler
– infeed unit
– pre-straightener
– circular-blade shear
– loop
– braking and stretching unit
– recoiler

– unloading and sorting unit
(other options are available, such as: rubber roller bridle, automatic blade change, scrap winder or cutter, etc.)

GEIT manufactures and supplies slitting lines for different materials:
– Hot or cold rolled steel
– Galvanized steel
– Pre-painted steel
– High tensile steel
– Stainless steel
– Aluminum
– Zinc
– Copper
– Alloys

Exit Coil Weight 13,600kgs 13,600kgs
Exit Coil ID 508mm 508mm



Three stages of speed and accuracy:
1. Stage one

Mandrel and automatic coil tracking system:
Mandrel drives the material along the line, to the tension stand
Automatic coil tracking system compensates when the strip deviates from the centreline by moving in the opposite direction until the coil is centered again
Material is then sent to the crop shear for initial square edge
2. Stage two
Slitting head:
Traversing base allows the slitter to “float” with the strip while running. This side to side adjustment is motorised
System prevents additional camber from being introduced into the slit strips
Slitter features:
Fully automatic pass line compensation
Automatically adjusts to different knife diameters
Compensates for material thickness
PE coating ability for both sides
Scrap choppers cut the edge trim and conveyor
system carries the scrap to bins

3.Stage Three:
Tension system,exit crop shear and recoiler
Automatic tension system assures proper winding tension
Exit crop shear cuts the coil ahead of recoiler to eliminate the need for rethreading the entire line when breaking down coils
Mandrel gripper compensates for thickness variations across the width of the strip
Recoiler tail hold-downs and controls strips, which prevents loose tails at the end of the run

GEIT slitting lines include several devices to minimize set up times.
Depending on the general line layout, Stam can offer:
– Automatic coil loading
– Automatic leading end cropping
– Automatic changeover of the slitting head (shuttle system)
– Automatic blade changing using a turnstile system
– Automatic blade locking
– Braking pads (a highly developed technology to such material type and surface)
– Mechanized pad changing system for the pads
– Automatic strip tail end trimming
– Automatic recoiler
– Integrated strapping systems
