So we have suggested as the profile of about one day (good if you have heavy books) rolled lengthwise. After that, the inclination was gone down to roll together almost by itself again. So taken measure and with a small miter saw (utility knife is very difficult and I would not usually recommend) cut. Then a trial basis and applied at one end of a few centimeters, the protective film from the adhesive strips. Held this protective film and then pressed profile along its entire length to. Then inched removed the plastic foil and pressed profile. This work, it is best to make your partner.
Unfortunately, the bad surprise came the next day. In many places, the profile had dissolved again, even the press again did not yield any lasting improvement. Remedy then brought the use of a special adhesive silicone. When replacing the bar a few points went from barely so partly seems the adhesive on the strip to be very good, then probably rather less. The manufacturer should urgently rectify. The adhesive silicone profile holding now but bombproof.
Too bad I find that I get only 5m length. So if I need 6 m, then I have 80% wastage. Again, I think it would be good if it, say the profile times even in 2m length would be.
