Abstract
There are provided a feed roller 1 for feeding a punched sheet and a press roller 6 disposed above the feed roller 1, which elastically pinch a tip end portion of the punched sheet 2 fed between the rollers. An actuator 7 actuates the press roller 6 to move along a circumferential surface of the feed roller 1 at the same speed as that of the punched sheet 2, whereby a portion 2a surrounded by cuts is separated from the punched sheet 2.
Claims20
A separating apparatus for a punched sheet having a portion surrounded by cuts comprising:
- a feed roller for feeding the punched sheet;
- a press roller disposed above the feed roller to elastically pinch with the feed roller a tip portion of the punched sheet fed therebetween;
- a connector for rotating the press roller and the feed roller at the same surface speed;
- and
- an actuator for actuating the press roller to move along a circumferential surface of the feed roller at the same speed as that of the punched sheet to separate the portion surrounded by the cuts from the punched sheet.
A separating apparatus for a punched sheet having a portion surrounded by cuts comprising:
- a feed roller for feeding the punched sheet;
- a rotation support plate disposed at one side of the feed roller;
- a pair of separate press rollers journaled on the rotation support plate at an angular spacing of 180 degrees from each other;
- a connector for rotating the press rollers and the feed roller at the same surface speed;
- and
- an actuator connected to the rotation support plate to rotate the rotation support plate such that the press rollers move along a circumferential surface of the feed roller at the same speed as that of the punched sheet.
