1. A method for preparing a pre-form comprising at least two layers of fiber tows being at least partly fixed by a resin, the method comprising:
providing a work surface; fixing a first end of the fiber tows to a first device; coupling the fiber tows to a second device such that the fiber tows are able to move relative to the second device; distributing a first layer of a resin onto the work surface; distributing a first fiber layer of individual fiber tows onto the first layer of resin by moving the first and second devices relative to each other; distributing a second layer of resin onto the first fiber layer; and distributing a second fiber layer of individual fiber tows onto the second layer of resin by moving the first and second devices relative to each other.
