ABSTRACT:
A yarn cutting apparatus comprising a cutter body, piston and a cutting mechanism. The cutting body has a cylindrical bore extending from a first end to a second end and a body notch extending transversely from one side to the other side of the cutter body. The cutting mechanism comprises a first cutting element, having an element notch and a planar support surface and a planar cutting surface parallel with the support surface, slidably mounted in the cutter body to move within the cylindrical bore and a second cutting element resiliently mounted in the cutter body adjacent the body notch. The second cutting element has a cutting edge and a planar surface that is parallel with and in surface to surface contact with the planar surface of the first cutting element. The piston is slidably fitted into the bore and engages an end of the first cutting element adjacent the first end of the bore, while the opposite end of the end of the first cutting element is attached to a bearing element slidably fitted into the bore. The cutter body further includes a support attached adjacent to the body notch and opposite the second cutting element for engaging the planar support surface of the first cutting element to resist rotation of the first cutting element due to the urging of the second cutting element.
