ABSTRACT:
A hand-held tufting mending gun has a piston within a cylinder pivotably mounted on a plate, the piston rod being eccentrically connected to a crank pin on a rotatable drive disk. The plate has an inlet port and an outlet port for registering cyclically with a respective port at each end of the cylinder. When an inlet port registers with a cylinder port at one end, the other cylinder port registers with the opposite outlet port. Also eccentrically connected to the drive disk is a needle driving crank arm for reciprocating a shuttle carrying a hollow needle carrier supporting a hollow needle. A high pressure air source fed to the gun housing is directed to the inlet ports and to the needle carrier, the latter for blowing the yarn through the hollow needle. Air entering the inlet ports feeds first one cylinder port and then the other to drive the piston, and exhausts from the unfed end of the cylinder through the cooperating outlet port.
