Abstract
A weaving apparatus used to separate the tubes of a heat exchanger so that spacers that hold the tubes apart can be inserted between the tubes to increase thermal efficiency. The weaving apparatus includes a frame assembly and a weaving mechanism contained within the frame assembly. The weaving mechanism includes an alignment plate to align the tubes and separation plates to separate the tubes after they have been aligned. The weaving apparatus thus automates the step of separating the tubes of the heat exchanger so that the spacer can ready inserted between the tubes.
