+x konaMike - 10/1/2020 3:30:46 AMHi there,I am looking for a method or technique or just ideas for “spreading” carbon tow as it is being wound off a spool and onto a “sheet making” drum. I have seen a couple YouTube videos of this process at a distance in a commercial setting but you cannot tell what exact technique/mechanism is being used to spread and thin the tow. I expect it may be a combination of pressure with some form of combing device. Wondering if anyone on the forum has knowledge of how this is done?
