Relaxation Module REL

for PVB interlayer

REL is a relaxation unit for the continuous PVB SHAPING AND CUTTING LINE.

PVB film, treated in the shaper, obtains its final shape and dimensions during a relaxation time. After the shaper PVB runs to REL, where it can freely relax, proceeding simultaneously to the cutter.

REL can also be used individually as a buffer of stretched or shaped PVB interlayer, which can be left in the stationary REL and then cut at a later stage.
