“…The R2R continuous process system is used to manufacture functional layers for flexible photovoltaics, electrolyte layers of solid oxide fuel cells (SOFCs), thinfilm transistors (TFTs), and organic light-emitting diodes [8][9][10][11][12][13][14][15][16][17]. Many of the common problems facing various applications using R2R continuous process systems are caused by the viscoelasticity and thermal characteristics of the polymer-based web, which is the base of functional layers [18][19][20]. The web in these systems refers to the film that becomes the base of a functional layer coated or printed through slot-die coating or gravure printing.…”

“…In the research on modeling and design of a decentralized controller for web processing, Pagilla of Texas A&M University reported a significant reduction in the deviation of tension control compared to proportional-integral tension control system [17]. Furthermore, Lu and Pagilla proposed a register control scheme that considers the thermal strain due to heat conduction from the heating roll [18] and developed a solution that involved utilizing a feedforward control to regulate web tension in the R2R manufacturing systems after confirming the feasibility of the control scheme [19][20][21]. Shin of Konkuk University was able to reduce the tension deviation generated by roll shape defect to 50% of the original value by using rotational torque compensation [22].…”

“…Plastik, ambalaj, tekstil, baskı ve laminasyon gibi endüstriyel alanlarda merdane üzerinden geçen malzemenin sıcaklığının homojen ve sabit olması gerekir. Malzemenin gerek kalınlık gerekse yüzey kalitesi, malzeme üzerinde oluşan ısıl gerilmeler ile ilişkilidir ve malzemeye etkiyen gerilmenin miktarı sıcaklıktan doğrudan etkilenmektedir (Lu ve Pagilla, 2014). Yüzey sıcaklığı ise, merdane içerisindeki kanal geometrisi ve çalışan akışkanın hareketi ile ilişkili olduğundan, ısı transfer merdanelerindeki halka akış kanalı geometrileri ile ısıl performans arasındaki ilişki incelenmesi gereken bir konudur.…”

“…Kompozit malzemelerin üretiminde ısıtma ve soğutma merdaneler ile gerçekleştirilir ve bu üretim sırasındaki ısıl davranışın modellenmesi önem taşımaktadır. Ancak bu modellemelerde de ısıtma ve soğutma etkisinin üretim malzemesi üzerindeki gerilim etkilerine odaklanılmıştır (Lu ve Pagilla, 2014). Yapılan deneysel çalışmada ısı transferi ile üretim malzemesinin merdane yüzeyine tutunma davranışındaki değişiklikleraraştırılmıştır (Jones ve ark., 2011).…”
