Tentering chain guide track for roller-supported tenter clamps

摘要

The guide track for a tentering chain carrying roller-supported tenter clips or clamps has two band-shaped flexible parallel guide rails extending horizontally along the edge of a material web, but protruding in an upright or on-edge manner perpendicular to the material web. The tenter clips have running rollers arranged in the material tentering plane and contacting respective opposite vertical surfaces of the guide rail arranged closer to the material web for taking up horizontal forces. The tenter clip reaches around the two guide rails in a C-shape so that an upper support roller contacts the upper edge of the guide rail lying closer to the material web for supporting the weight of the tenter clip and so that a lower support roller contacts the lower edge of the other guide rail for taking up any tipping or tilting moments of the tenter clip.
