The present invention during operation, as well as to significantly improve the needle adjustment cam device of the structure of a racing cam unit and the transfer cam unit and its installation structure which can be set in an deotbeoseon knitting simplicity of structure, as well as contribute to increase smoothly and efficiency of operation to decrease the malfunction and failure rates that may be involved relates to a new drive system significantly advantageous.
That is, in groups a normal deotbeoseon knitting is inclined induction cam drive is installed, the second driving apparatus equipped with racing cam and the transfer cam and integral, at the rear end of the operating plate being bent in a "b" type, constant additional configuration and installation bracket with the size of the assembly of the home (one-piece or a signed type, etc.), and above installed and bracket assembly groove has a straight push rod projecting in front and rear, the air supply valve is coupled with two drive air for while at the same time entered into the configuration the cylinder, the upper surface at the time of forward movement of the push rod of the two-stage upper body block of the push rod and maintain a constant gap projecting front the air cylinder for driving (304) no longer be advanced in its front as garomakah Jersey, it will have a two race cam drive or transfer, including the air cylinder mounting bracket, operated by a cam plate fixed to add a touch more fixed block that allows for a rather backward as his jersey distance.
