Press Release number: 01405SHEAR
A brand new range of Micropro® 11-roll straightener-feeders offering a wider working range in strip sizes and material grades from Dimeco Alipresse is now available through Shear-Form Machine Tools Ltd, the Coventry based sheet metal and plate working machinery supplier and sole UK representative for Dimeco Alipresse
Using the latest 3D design and finite element modelling systems, the Micropro® 1690NG range of 6 versions, has been developed to give fabricators the ability to use a wider range of strip sizes from 300mm – 1,500mm wide with a working thickness down to 0,9mm from 1mm found in earlier models, whilst the maximum working thickness is 8mm. The straightening quality is improved by using 7 x small 90mm diameter motorised straightening/feeder rolls and 4 x 90mm pinch rolls with 10mm roll adjustment stroke, double that in previous straightener-feeders. All the rolls are case hardened (60Rck) and ground for a longer life. The maximum operating speed is 30m/min
This straightener-feeder can be operated through either pneumatic cylinders or servomotors for a more accurate release timing adjustment. Standard SIMOSTAR® and OPTIMASTER® controls can be retrofitted to the Micropro® 1690NG straightener-feeder.
Using 3 or 5 back up rolls in the wider models, the workable material range is expanded by up to 76% for 1,300mm wide strip and by 20% for 800mm wide strip, whilst lubricated bearings offer the user reduced maintenance.
This new straightener-feeder also has a new patented cost efficient pinch release system, giving an integral 3mm lift of all the rolls through 2 pneumatic jacks.
