As it is normal practice for Tecno Paper, who has the capability and the flexibility to customize its winders to the requirements of any specific application, the inquiry of the customer has been deeply analysed to find the specific solutions in consideration of the productivity, quality of final products and safety features required by the project.
The technological solution proposed is a winder of the family “High Performance”, but the model that will be supplied is an evolution of the models supplied in the past to customers located in different areas of the world (Italy, Poland, Indonesia, Argentina, Bangladesh, India).
The winder line is composed by three unwind stands and winding head. The paper width at unwinding is 2750 mm, the diameter of mother reels is 2500 mm, the diameter of finished reels is 2000 mm and the operation speed is up to 1500 m/min.
Following the product flow, the first new feature is at the unwind stands. They will be able to receive mother reels wound on cores, in which expanding heads will be inserted in order to be loaded in the seats on the stands. First change respect to the standard solution is the clamping system, keeping the expanding head safely blocked in the seat, that is operated by hydraulic cylinders instead of pneumatic ones. This solution assures the perfect stability and the absence of dangerous oscillations of the reels.
The competitive advantage of Tecno Paper is flexibility and optimization of its products and solutions
Still on the unwind stands, a second cross movement has been added to the standard one used for the mother reel centering. The additional one allows the change of the distance between the two seats holding the reels, in case the center line of the bearing housings changes due to different cores length or due to improper insertion of the expanding heads in the cores. The operation of the system is by electro mechanical systems on each unwinder with manual control of the operator from outside the safety fences.
