  • Patent number: 4316866
    Abstract: Cutting wire for a brick and tile cutting and setting machine is wound on supply spools. A plurality of the supply spools are mounted below the cutting frame of the machine. The supply spools are braked to prevent rotation by inflatable brake hoses. When the hoses are inflated, they push against the spool. The wire from the supply spool extends across the cutting frame to a take up spool. The take up spools are mounted on a shaft for rotation. After a set number of bricks have been processed, the wire is spooled from the supply spool to the take up spool so that new, unworn wire is stretched across the cutting frame. The wire on the supply spools is held in place by a flat spring which prevents the wire from unwinding.
