    摘要： A method of accurately punching holes into a moving web of a thermoplastic film material, and more particularly, punching holes into the web through the intermediary of a rotary serrated tube punch. The invention relates to accurately punching holes into an advancing web of thermoplastic film material utilizing a novel rotary serrated tube punch. The film web is continuously advanced over at least a portion of the circumferential surface of a rotatable anvil roll, and tensioned against the anvil roll surface through the use of suitable tensioning devices, such as tension rollers arranged upstream and downstream of the anvil roll. At least one opening is formed in the circumferential surface of the anvil roll which is slightly larger than the size of the hole which is desired to be punched into the film web through the use of the inventive rotary tube punching arrangement. The rotary tube punch possesses a serrated cutting edge at its radially outermost end, and is adapted to be rotated in synchronism with the anvil roll so as to cause the serrated cutting edge pierce through the web in a precisely aligned position with the opening in the rotating anvil roll, and to thereby produce an accurately dimensioned hole in the moving web without the necessity for stopping the web. The anvil roll may be constructed hollow, and communicates with a suctioning source for aspirating punched out film material segments.

    摘要翻译： 一种将热孔精确地冲孔到热塑性薄膜材料的移动纤维网中的方法，更具体地说，是通过旋转锯齿形管冲头将冲孔穿入网。 本发明涉及使用新颖的旋转锯齿形管冲头将孔精确地冲孔到热塑性薄膜材料的前进纤维网中。 薄膜网连续推进到可旋转砧辊的圆周表面的至少一部分上，并且通过使用适当的张紧装置（例如布置在砧辊的上游和下游的张紧辊）张紧在砧辊表面上。 通过使用本发明的旋转管冲压装置，在砧辊的圆周表面中形成至少一个开口，该开口略大于期望被冲压到薄膜腹板中的孔的尺寸。 旋转管冲头在其径向最外端具有锯齿形切割刃，并且适于与砧辊同步地旋转，以使锯齿状切削刃与旋转中的开口精确对准的位置穿过腹板 砧辊，从而在移动幅材上产生精确尺寸的孔，而不需要停止幅材。 砧辊可以被构造成中空的，并与抽吸源连通以吸出冲压的薄膜材料段。

    摘要： A quick change punch reel for a rotary press comprises a transversely split annular main body member having radially extending cylindrical sockets for receiving individual punches, each punch having a head and a base and an outer cylindrical sidewall with a circumferential undercut including a tapered wall extending toward the base of the punch. The sockets are adjacent a planar side face of the main body member and cylindrical bores are formed through the side face in alignment with and intersecting the sockets with the bores having counterbores at the side face. Punch retaining plungers are spring-biased into the bores and counterbores by means of a transversely split cap plate which is secured to the side face of the main body member. Cylindrical punches may be exchanged in the sockets by retracting the plungers against the compressive force of individual springs such that the punches are received within the sockets and retained by spherical heads of the plungers within the undercuts of the punches. Preferably, the punches are retained with their bases fully seated within the sockets by the heads of the plungers engaging the tapered sidewalls of the circumferential undercuts of the plungers to exert an axial seating force on the punches.

    摘要： A continuously moving web passes over a fixed female die, which die is slotted to define a U-shaped cutting edge. A cylindrical punch rotates on an axis above the path of the web so that a cutting edge defined at the free end of the punch moves into the slot defined in the fixed die to cut a tab in the web. The length of the tab so cut can be varied by changing the relative speed of movement between the punch and that of the web, and the punch is mounted at an offset to its rotational axis. If such offset is positive, that is in the direction of rotation, the tab can be formed to "lead" the web. Providing the offset in the opposite or negative direction, the tab "trails" the web.

    摘要： A punch for punching a workpiece. In particular, the invention relates to a punch including a base to stably support the punch and a support member configured to accommodate and locate the workpiece in a punching position. The support member is preferably movably connected to the base and preferably includes at least one punch member configured and operably associated with the support portion to punch the workpiece in the punching position upon an actuation movement of the support member with respect to the base. Another embodiment of the present invention relates to a punch having a paper tray oriented at an angle with respect to the base to support a sufficient portion of a sheet of paper to prevent an unsupported portion from falling over and withdrawing from the support portion. In particular, the paper tray and punch mechanism are oriented to expel paper chips such that the chips are visible to an operator as they are punched.
