ABSTRACT:
An apparatus for measuring the thickness of a coating on a continuously moving strip of material. The apparatus includes a frame (10), a shuttle (24) mounted on the frame for reciprocal movement thereon, an engaging pin (174) carried by the shuttle and capable of engaging the moving strip to cause the shuttle to be moved by the strip, a drive (120, 122, 118, 126, 116, 114, and 112) capable of moving the shuttle in a direction reverse to the movement of the strip, and measuring means, at least a portion of which is mounted on the shuttle. The apparatus further includes a support (172) mounted on the shuttle and capable of supporting the strip when the engaging pin is engaging the moving strip, and structure capable of adjusting the support (172) towards and away from the portion of the measuring means mounted on the shuttle to establish a predetermined spaced apart measuring distance. The drive means includes an improved connection between a drive chain (112) and the shuttle (24), the improved connection including a pair of pins (138), a saddle block (140), a reciprocal yoke (114) and a drive pin secured to the saddle block and rotatably journaled in the yoke.
