Abstract

318,992. Mannesmannr÷hren-Werke. Sept. 14, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Punching. - Tubes are supported internally while being perforated by a punch d, by means of a member b in which the punching-die f is mounted, the part b being supported by a wedge c bearing against the opposite wall of the tube. The wedge is moved axially relatively to the punching-die after each operation of the punch, to allow the work to be fed. The actuation of the wedge may be effected in known manner by a curved disc and a flexible intermediate member. The die-holder may be so formed as to be actuated by a conical mandrel. In a further modification, the adjustment of the diameter of the die-holder can be effected by an eccentric.
