は比較的簡単であつた。(Prior Art) There are two types of pipe stringing machines: those that use spinning processing and those that use bulge processing. This invention belongs to the latter category, but the conventional bulge-forming tying machine wraps a pipe with a mold of a desired shape and applies strong pressure inside the pipe with pressurized oil or molding rubber.
Although this string pulling machine uses strong pressure and requires careful preparation, the work of supplying and taking out the tubes itself was relatively simple.

て実用し得なくなるおそれがあつた。 The above-mentioned disclosed invention involves inserting a molding elastic body such as rubber into a tube to be processed, and front and rear core metals that sandwich it, applying a mold to the outer periphery of the tube, and molding the molding elastic body using the front and rear core metals. This is a stringing machine that creates an annular bulge on a part of the tube wall by squeezing it. Since this is a tube supply/removal device for this stringing machine, the long tube supplied must be inserted into and extracted from two core metals at the front and back, which were absent in the conventional Basil type stringing machine. If it took time to supply and take out the tubes, there was a risk that the above-mentioned invention would become inefficient and could not be put to practical use.
