ABSTRACT:
A selvage forming and cord catching device for use in a loom includes a base adapted to be secured to the loom and has two planetary gear systems mounted on it. Each of the planetary gear systems has two planetary gears orbiting about a central axis. A cylindrical yarn guide member is secured at the center of each of the planetary gears to allow yarn to extend through the center of each of the planetary gears. The yarn is brought through a guide arm mounted on each of the planetary gears in an eccentric manner so that when the planetary gears rotate, the yarn passing out of each of the planetary gears of each of the planetary gear systems are fed to the loom in an inter-crossing and inter-winding manner to wind around each other. The yarn from one of the planetary gear systems is fed to the loom to form the selvage. The yarn from the other one of the planetary gear systems is brought to a particular position to pinch therebetween the excessive length of the wefts and carry away the excessive length of the wefts after such is cut by scissors.
