Abstract
An improved structure yarn cylinder that is an improvement of “Yarn Cylinder with Trench” (Taiwan P/N 201810) accomplished by extending the circumferential length of the trench, disposing numerous teeth at differing angular orientations along the two lateral walls of the trench and, furthermore, arraying the teeth in a crisscross formation on the two lateral walls to thereby effectively increase yarn snagging capacity and facilitate ease of securing.
Claims1
An improved structure yarn cylinder consisting of a hollow columnar member utilized for winding yarn, wherein the said columnar hollow member is of one-piece plastic construction with a trench of an appropriate depth and width formed around its circumference;
- the said trench structure secures the end of the yarn such that when the yarn is wound around the yarn cylinder, the yarn will prevent from loosing and slippage, wherein the improvement comprises that a circumferential angle of the said trench is at minimum 350 degrees, numerous teeth are disposed at differing angular orientation along two lateral walls of the said trench and, furthermore, the said teeth are in a crisscross formation on the said two lateral walls;
- as such, a longer circumferential length of the said trench and a contrastive skewing of the said teeth effectively increases yarn end snagging capacity.
