Hair rooting apparatus with its hooked needle moving also transversely

A device for knotting specific lengths of fibers onto a base material, said device comprising:

• at least one double-hooked needle with a smaller hook at the lowest portion thereof and a larger hook on said needle above said smaller hook;
• holding means for holding said needle, said holding means being comprised of:
• a support frame, and
• a needle bar slidably fitted within said support frame with said needle connected to the bottom thereof,
• a rotatable drive shaft;
• a first cam means operatively connected to said drive shaft and said needle bar for moving said needle bar vertically to varying predetermined heights and depths during the formation of each knot;
• a second cam means operatively connected to said drive shaft and said support frame for moving said support frame and said needle therein transversely in the open direction of said smaller hook in a timed relationship with the movement of said first cam means;
• and
• a frame on which said holding means, said drive shaft and said two cam means are mounted;
• whereby rotating said drive shaft simultaneously operates said first and second cam means so that said needle is moved to a lowest position beneath said base material and then raised to a first intermediate position above said material by said first cam means followed by said second cam means moving said support frame and said needle bar connected thereto transverse to the vertical movement of said needle when said needle is in said first intermediate position, then said first cam means at least one time lowers said needle beneath said base material a distance less than said lowest position followed by returning said needle vertically above said base material, and finally said support frame is returned by said second cam means to its original position by a reverse transverse movement when said needle is in its highest position above said base material.
