Temac<\/a>, a leading Italian manufacturer of slitter rewinders and special machines, has announced significant advancements in web tension management for packaging and converting applications. The company\u2019s latest innovations ensure superior performance in processing flexible packaging materials<\/a> such as BOPP, OPP, CPP, PET, PVC, LDPE, HDPE, paper, and multilayer laminates including PET + ALU + LDPE.<\/p>\n During both unwinding and rewinding operations, precise web tension is critical to achieving defect-free, uniform reels. Temac\u2019s engineering solutions guarantee optimal control throughout the entire process, from the mother roll to the finished reel.<\/p>\n In its slitter<\/a> rewinders, Temac integrates a dedicated servo motor on the unwind section\u2014an asynchronous A.C. vector motor managed by a digital inverter\u2014ensuring highly accurate automatic tension management. Unlike traditional systems that rely solely on pneumatic brakes, Temac\u2019s servo motor operates as an additional drive motor, complementing the draw and rewind motors. This configuration delivers precise control directly from the machine\u2019s PLC with minimal response time and without operator intervention.<\/p>\n The pneumatic brake remains part of the system but is dedicated exclusively to emergency or power outage scenarios, reducing wear and extending component life. Moreover, the servo motor provides energy regeneration, significantly lowering energy waste and minimizing particulate emissions caused by brake pad wear.<\/p>\n Another critical element in maintaining consistent web tension is the rewind shaft, which must be equipped with next-generation friction technology.<\/p>\n Temac’s slitter rewinders are fitted with friction shafts featuring newly patented rings mounted on ball bearings, which significantly reduce the inertia during engagement and anchoring phases.<\/p>\n These rings are also extremely lightweight, being manufactured from a special aerospace-grade aluminum alloy with an anti-wear heat treatment. Each ring weighs exactly one-third of its traditional steel counterpart.<\/p>\n The reduced weight is particularly beneficial during shaft core size changes (e.g., from 70 mm to 76.2 mm and vice versa), facilitating easier handling and positioning. This translates into exceptionally low inertia, making these friction rings highly efficient and delivering outstanding tension control over processed materials.<\/p>\n With these advancements, Temac reinforces its leadership in film processing technology. Its focus on precision, efficiency, and operator-friendly design ensures customers achieve maximum performance in flexible packaging production.<\/p>\n<\/div>\nOptimized Unwinding with Servo Motor Technology<\/h4>\n
