摘要： In an apparatus and a method for forming threaded portions around a metal pipe with accuracy and ease, a preliminary forming is performed so as to recess portions of the metal pipe a little bit inwardly in the radial direction thereof by advancing auxiliary forming punches while keeping main forming punches as they are. Thereafter, by receding the auxiliary forming punches back, while advancing the main forming punches, simultaneously, the threaded portions are formed on outer periphery of the metal pipe 3 shifted by 180null in phase thereof.

摘要： An improved apparatus for on-line inspection of an intermediate-stage, headed, non-threaded blank for a threaded fastener is disclosed. If the blank fails to meet specifications, the production of blanks is terminated. Improvement features include a roll-sorter for testing all blanks to see if certain dimensional parameters of the blank's head are satisfied. Then, random chosen acceptable blanks are fed to a rotatable table which is constructed to receive a sample blank for movement of the blank to a test station where the blank is tested for other failures to meet dimensional specifications. The rotatable table is constructed to provide interchangeable elements thereof that will accept blanks of different head and stem sizes. Multiple adjustability is provided in the means for transferring blanks, that are first acceptable to the roll-sorter test, on to the rotatable table for further testing.
