摘要:
A method of pilgrim step rolling of elongated stock includes reciprocating a roll stand or frame for moving the stock either by rotating it and/or advancing it; such a method is improved by providing a first component of movement at a constant speed and adding thereto, near each dead center portion of the reciprocating frame movement, a second component of motion including temporary accelerating and decelerating periods.
