MULTI-LAYER ARRANGEMENT OF A TUBULAR NET ON A SUPPORT TUBE, AND DEVICE AND METHOD FOR OBTAINING SAME

摘要

The invention relates to a method and means which are used to obtain a multi-layer arrangement of a tubular net (6) which is first positioned on a transfer tube (3). According to the invention, a toothed loader (5) is used to slide the net (6) along the outside of the transfer tube (3) to the end thereof, said end comprising a slightly-conical end zone (4). When the net (6') reaches said end zone (4), it falls on to the support tube (1) owing to the elastic tension thereof, such that the net is loaded onto the support tube (1) in an arrangement of concentric layers (6'). In this way, the outer layers of the loaded net (6'') have a maximum diameter equal to that of the transfer tube (3) while the inner diameter of the loaded net (6''), which corresponds to the outer diameter of the support tube (1), is less than the maximum diameter of the stretched net.
