A tenter clip closer of the present invention has a first closer comprising a cam and a second closer comprising a freely rotatable disk. A tenter clip opening apparatus of the present invention comprises plate-shaped opener fixed rotatably and also driven by a forcing means to resist clip arm, and when an abnormal force acts on the plate-shaped opener because of malfunctioning clips, the plate-shaped opener pivots away from the malfunctioning clip against the forcing means. A device used for detecting defective tenter clips of the present invention has at least one tenter clip actuator for opening or closing the tenter clips. When the force exceeds a reference value, a signal from the monitoring means automatically activates a counter for automatically counting the number of clips that have contacted the actuator after the malfunctioning clip. |
