Abstract: A tower houses a forming mill which shapes and feeds forward a strip of metal having an upstanding male locking hook along one edge and an upstanding downwardly opening female locking strip along the other edge. A substantially semicylindrical mandrel lower part has an end secured to the tower and projects horizontally outward under the mill at an angle to the strip. The mandrel upper part has a flat plate pivotally connected to the lower part and bears a way in which a slide carrying a curved guide plate is adjustably positioned. The mandrel parts may be adjusted angularly in a horizontal plane and locked in position and the slide is linked to a turntable slide carrying a lower pinch roll which may be angularly and vertically adjusted in position. The tower carries an upper pinch roll and a bending roll for bending the strip downward. The bent strip is guided angularly and downwardly by the forward side of the mandrel lower part toward an exit conveyor for carrying away the formed pipe. As each turn of strip around the mandrel approaches the top it is angularly guided by the curved guide plate so that the male locking hook of the turn engages the female hook of the next turn and the pinch rolls clinch the hooks for continuously forming the spiral-seamed pipe.
Abstract translation: 塔架容纳成形磨机，其成形并沿着一个边缘向前成形具有直立的阳锁定钩的金属条，以及沿着另一边缘的直立向下开口的雌锁定条。 基本上为半圆柱形的心轴下部具有固定到塔的端部，并且在与该带条成一定角度的水平向外突出于铣床下方。 心轴上部具有可枢转地连接到下部的平板，并且承载载有弯曲导向板的滑块可调节地定位的方式。 心轴部分可以在水平面中成角度地调节并且锁定在适当位置，并且滑动件连接到承载下夹送辊的转台滑块，所述下夹具可以在位置上被角度和垂直地调节。 该塔承载有一个上部夹送辊和一个用于向下弯曲钢带的弯曲辊。 弯曲的条带被心轴下部的前侧成角度地向下引导到出口输送机，用于带走形成的管道。 随着围绕心轴的每一圈的条带接近顶部，其由弯曲的导向板成角度地引导，使得转向的阳锁定钩接合下一匝的阴钩，并且夹紧辊紧固钩以连续地形成螺旋形的， 缝管。
