Claim 15:
16. A system for indicating when a defective zipper profile extruded onto a generally flat plastic web moving in a feed direction in a re-sealable container production line, the system comprising: a sensing device for detecting the defective the zipper profile; a web distortion device in communication with said sensing device for deforming the generally flat plastic web during the production in response to the sensing device detecting the defective zipper profile, the web distortion device comprising a support and opposing pusher members connected to the support and defining a space therebetween for the generally flat plastic web to pass, the pusher members being movable relative to the support between a noninterfering position when the sensing device does not detect the defective zipper profile and an interfering position when the sensing device detects the defective zipper profile, pusher members being configured in the noninterfering position to allow the generally flat plastic web to travel in the feed direction uninhibited and being configured in the interfering position to distort the generally flat plastic web from its generally flat configuration; a roll supporting device positioned with respect to the web distortion device so that deformed sections of the generally flat plastic web remain deformed as they move onto said roll supporting device so that a segment of the generally flat plastic web containing a defect is conspicuous on the roll.
