Link cutter

摘要

A link cutter includes a support frame having a cutting zero, a first conveyor on one side of the cutting zone for sequentially conveying a plurality of links interconnected by twisted casing sections, a second conveyor on the opposite side of the cutting zone for receiving links from the first conveyor and stretching the twisted casing sections at the cutting zone. A sensor upstream of the cutting zone includes a source of electromagnetic waves directed across the path of the links and a device for sensing those waves which pass between the links adjacent the twisted casing sections so as to actuate a knife within the cutting zone to sever the sensed twisted casing section upon movement of the same to the cutting zone. The sensor may be a light source and photocell adjustably mounted relative to the cutting zone.
