Tests running 24/7:
For some time now, Ole Christian has been running performance tests on new components.
Thanks to sensors and logging software, the tests run around the clock, workdays and weekends!
Right now we have one valve that has performed flawlessly for more than 2 million cycles: Translated into weaving, it corresponds to almost 4 million picks of tabby. If you weave 10 picks per cm, it corresponds to 2000 meters (~ 1 ¼ mile).
If you weave 10 picks per minute, it corresponds to roughly 3 300 hours. On average, the hour counter in the control cabinets for the TC-1 shows an annual average of 300 hours ~ 11 years of weaving!
A web camera has been pointed towards the test bench, so that all the team members can log on whenever they want, and observe the ongoing tests. In a few weeks I’ll let you know how much "weaving" has accomplished!
Anders is running some tests for the warp advancing mechanism, based on different warp tensions. We want the loom to be able to increase and decrease the warp tension, and it should be able to wind the woven fabric off the fabric beam or the warp off the warp beam. These operations will require more force if the loom has many modules (=many warp ends) and if you want a high tension warp. The tests have been going on for several weeks to see what parts will wear out first, and in what ways. The purpose is to identify possible design flaws BEFORE starting fullscale production!
Bjørn Haavard has developed a new manifold for the pneumatics. Up till recently we used a manifold assembled from 96 parts. The new manifold consists of 3 parts, and it performs BETTER than the old one! The new manifold is furthermore designed to fit inside the left or right side compartment of the TC-2 loom! A pity that it will not be visible!
Bjørn L on the electronics:
The biggest news is that the modules will have a WIRELESS connection to the loom!
Here from testing of antennas and elecronics:
Jan writes the software, and says that it is beginning to "talk to" the electronics!

Isn't it AMAZING that so many highly skilled people put their minds into developing a new TC-loom!
