制造方法和利用所述方法制造的用于栅栏的多功能管柱
摘要：
本发明涉及一种制造方法以及由此获得的多功能管状支柱，所述支柱(1)用作带有金属网的栅栏的支撑，每个支柱设有多个接合元件(2－2’)，该方法包括步骤：利用层压薄片卷切割薄片部(3)；折叠所述薄片部，直到获得管柱本体，其自由端相对；并连接所述自由端。该方法另外包括为了限定多个凹槽(4－5)在切割步骤和折叠步骤之间实施的冷成型步骤，凹槽的位置和形状与接合元件(2－2’)的位置和形状相对应，上述凹槽(4－5)的长度与接合元件(2－2’)的外部轮廓的长度相等。
摘要（英）：

Manufacturing method and a multifunctional tubular post for fences obtained by said method, the posts (1) being used as support for a wire-mesh fence, each of the posts having a plurality of joining elements (2-2'), the method comprising the steps of cutting a portion of sheet metal (3) from a reel of rolled sheet metal, folding said portion of sheet metal until it forms a tubular body, the free ends of the latter being placed so as to face one another and said free ends being joined. The method additionally comprises a step of cold forming, between the cutting step and the folding step, in order to define a plurality of channels (4-5) whose position and form coincide with the position and form of the joining elements (2-2'), the length of said channels (4-5) being equivalent to the length of the outer contour of the joining elements (2-2').
