ABSTRACT:
This apparatus contains a plurality of die-forming roller pairs which form corrugations longitudinally in ductile strip material. The die-forming rollers are gear driven from an electric motor of adjustable speed. One die roller of each pair has an eccentric mounting to provide adjustment of the space between roller pairs. The side edges of the strip material are formed into an inside and an outside seam element. A pair of rotatably mounted curling rollers provides the corrugated strip material with the proper radius of curvature and helical angle for convolution into corrugated tubing. An adjustment means is provided which simultaneously sets the proper position both pivotally and laterally of said curling roller pair according to tubing diameter selected. Radially adjustable guide rollers guide the circumference of the strip during convolution. A pair of support rollers and a run-out table support the tubing as it is produced. A means for loading is provided to enable one to easily load spools of strip material. Lengths of tubing may be joined by reducing one's end diameter by rotation and inserting it into another section. After insertion the reduced diameter is rotated to expand back near its original dimension, thereby locking the two lengths together. A seam which allows adjacent strips to rotate with respect to each other permits the change in diameter.
