Abstract
A tubular net arrangement is made by placing a tubular net on a transfer tube and inserting a support tube coaxially inside the transfer tube. The support tube has a support tube diameter that is smaller than the transfer tube diameter. The tubular net is then moved off the transfer tube and past the end of the transfer tube to fold the tubular net onto the support tube in the form of multiple successive concentric layers. The transfer tube then moves relative to the support tube to expose the support tube as the layers are formed on the support tube. The inner diameter of each layer is adjacent the support tube and is equal to the support tube diameter and the outer diameter of each layer is spaced away from the support tube and is greater than the support tube diameter and at most equal to the transfer tube diameter.
