In tomorrow's world, renewable energies will cover the bulk of our energy needs. Along with
wind energy, the sun is assuming an important role as an energy source. To make the use of photovoltaic plants attractive and profitable for users, the modules must deliver high quality and a long service life. This is only feasible if all components within the module meet high quality standards. That is why, for example, firm bonding of the frame that holds the modules together is of the utmost importance. When the module is assembled, the framing tape, a double-sided DuploCOLL adhesive tape, produces a strong and long-lasting bond between the frame and the module. The more firm and secure the frame, the more stable the whole module will be. The framing tape can be applied by full-automated or manual processes.
Lohmann has been involved in the photovoltaic industry for decades and develops not only individual bonding solutions but also automated application tools. For example, the Building and Renewable Energies market segment has developed a spool-unwinder to apply the framing tape manually. It consists of a mobile or stationary unit housing the adhesive tape spool. The tape is attached to the associated manual applicator and flexibly affixed to the module frame. In this way, the spool-unwinder enables simplified application and improved ease of handling. Another advantage of the new unwinder is the use of the spool. In contrast to a roll, which holds just 50-100 m of adhesive tape, a spool can take 1400 m of tape. This difference in length makes it clear how efficient the spool-unwinder is to work with – there is no need for frequent changes of roll, minimising the time and effort required. The spool-unwinder is available in two models, as a stationary or a mobile unit. Both versions have tension-free tape application, making it easy to unroll the tape. Whatever the application, the customer then obtains an effective individual solution to bond framed photovoltaic modules.
