Abstract: A micro-needling device includes a hand-held motorized unit generates repetitive motion. An outer shell defines a cylindrical cavity therein and having a top surface. The top surface defines a plurality of needle holes passing therethrough. The outer shell is coupled to the hand-held motorized unit. A cylindrical plug member is disposed within the cylindrical cavity. A plurality of needles extends upwardly the plug member through the needle holes. A translation unit translates the repetitive motion from the hand-held motorized unit into oscillating inward and outward motion applied to the plug member so as to cause the plurality of needles to oscillate between an outward position in which the needles extend beyond the outer shell and an inward position as the rotary cam rotates about an axis.

Abstract: An automated yarn creeling method and apparatus for the textile industry. Preferably, the present yarn creeling system is used in the carpet tufting industry to automate, ultimately, the intelligent transfer of packages of yarn from the shipping pallets to the bullhorns of a creeler. The apparatus preferably comprises a service arm assembly, a vertical support, a base support, and automated weighing and control systems.
