Abstract: An apparatus for forming spiral steel pipe by separate type forming rolls which is characterized by stands carrying rolls for forming the inner and outer surfaces of the steel pipe, the stands being each split into two portions in a direction perpendicular to the axis of the steel pipe to be formed, one of the two portions being a fixed stand formed with a smaller length than the width of material plate for the intended steel pipe and the other portion being a stand movable in the axial direction of the steel pipe to be formed.
Abstract translation: 一种用于通过分离型成形辊形成螺旋钢管的装置，其特征在于用于形成钢管的内表面和外表面的支架辊，所述支架在垂直于钢管轴线的方向上分成两部分 要形成，两个部分中的一个是固定支架，其形成为具有比用于预期钢管的材料板的宽度更小的长度，而另一部分是可在待形成的钢管的轴向方向上移动的支架。

Abstract: Apparatus for producing tubing by welding helically formed metal strip comprises a mechanism for feeding the strip, a tube former which winds the metal strip helically to form the tube, a device for welding together the strip edges after it has been formed, a cutter for cutting the welded tube into lengths and a tube carrier for supporting these lengths of tube, the tube carrier being pivoted so that it can be swung to vary the angle between the axis of the formed tube and the direction in which the strip is fed, a receiver which receives the cut-off lengths of tube from the carrier and a conveyor for conveying the cut-off lengths from the receiver. The receiver is arranged so that each of the cut-off lengths of tube can be swung about the pivot axis of the tube carrier from a position parallel to the carrier and can also be swung about a second axis into a position in which each length of tube extends parallel to the conveyor which ten receives the tube and conveys it away.
