Abstract:
A drag board for use in a coil processing line for tensioning or wiping a continuous line of strip material using a substrate to which is selectively secured a contact pad. The leading edge section of the substrate is constructed and arranged for receiving a locking bar which may be activated to apply or release a compressive, securing force on one edge section of the contact pad. Releasing the locking bar permits removal of or emplacement of a contact pad from or onto the substrate.
