Visual inspection machine VM-1650

coated abrasivewebindustrial

The Web Vision machine is designed to unwind and rewind full jumbo roll, for operator to check web during unwinding/rewinding operation. Web runs up vertical at inclined angle to present web grain side to the operator. Operator can check the web and side attach a label where defect is detected. Features - Useful width: 1,650 mm - Unwinding station for rolls up to 1,200 mm dia., excluding expanding shaft - Automatic alignment of the unwinding material (automatic tracking) - Pneumatic unwinding brake, manually controlled - Web runs up vertical at angle for web show to operator - Catwalk in between unwinder and pulling station for operator visual material control - Variable speed drive up to 50 m/min - One motorized rubber covered shaft as pulling shaft, web runs over this shaft from the grain side - This motorized shaft is needed to separate tension between unwinder and rewinder - The rewinder is independently motorized able to manage 1,200 mm dia. jumbo - The rewinder is equipped with a 12 kW servo motor able to perform a maximum web tension of 3.5 N/mm decreasing to 1.5 N/mm at maximum jumbo diameter. - The complete machine is electronically controlled to automatically manage torque control on rewinding station. The installed software automatically calculates roll diameter on rewinder. - Feedback to the operator is given by display featuring also touch screen for parameters control. Options - Variable speed up to 80 m/min - Automatic unwinder brake management (jumbo diameter detection with close loop control on brake pressure)
