Abstract
A hand-held mending gun for tufting stitches into a backing material has a hollow needle reciprocally driven axially to form stitches in a backing material. A drive mechanism couples a rotary motor to a needle carrier for reciprocation along the axis of the needle. A yarn feed roll connected to a yarn drive disk may be selectively changed in speed by changing the position of the yarn feed disk relative to a radius of a drive disk through a pneumatic cylinder having a piston relocatable between an extended and a retracted position. With the speed of rotation of the drive disk constant, the speed of the yarn feed roll may be changed between a high and a low pile height setting, or position, by changing the distance of a contact point of the yarn feed disk on the drive disk from the center of the disk drive. A pneumatic selector switch allows a single operator to control the selection of the high or low pile height position.
