CYLINDER, SINKERS, NEEDLE

摘要

An element affixed to the top of a needle cylinder to cover at least the upper portions of some or all sinker slots and thereby provide the needle cylinder with a smooth upper edge for part or all of the circumference. Sinkers ride in the lower uncovered portions of sinker slots to which an element has been affixed. Sinker portions extend over the upper surface of the element and extend downwardly to engage the lower sinker slot portions from the needle cylinder interior. Alternatively sinkers may ride in the lower portions of covered slots by extending from exterior the needle cylinder directly to the slots. A needle or needles with a large head but narrow shank may be inserted in the needle cylinder at the portion where the element covers sinker slots.
