摘要:
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.
摘要:
A multi-layer arrangement of a tubular net is first positioned on a transfer tube. A toothed loader is used to slide the net along the outside of the transfer tube, to an end zone thereof which is slightly conical. When the net reaches the end zone, it falls onto a support tube in an arrangement of concentric layers. In this way, the outer layers of the loaded net have a maximum diameter equal to that of the transfer tube while the inner diameter of the loaded net, which corresponds to the outer diameter of the support tube, is less than the maximum diameter of the stretched net.
