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.
Claims12
A drag board assembly comprising:
- an elongated substrate having an upper working surface, lower surface, leading edge section, and trailing edge section;
- said leading edge section constructed and arranged for receiving one edge section of a contact pad;
- locking means for engaging the one edge section of the contact pad for selectively securing and releasing the contact pad in said leading edge section;
- and said locking means includes a power source for applying and releasing a compressive force on the one edge section of the contact pad.

A method of applying a contact pad to an elongated drag board, comprising:
- providing said elongated drag board with an upper working surface and having a leading edge section constructed and arranged for receiving one edge section of a contact pad,
- inserting the one edge section of said contact pad onto the leading edge section and over a lower surface of said elongated drag board;
- and
- securing the one edge section of said contact pad in the leading edge section of said elongated drag board;
- and
- said securing uses a power source for applying a securing force to the contact pad.
