Abstract
A winding tube has a tubular body and a removable and replaceable end ring. The end ring has opposite end faces that, according to one embodiment, each define at least two recesses that form start-up regions between the end ring and the tubular body for capturing yarn during a winding operation. The recesses are spaced apart from one another so as to allow the end ring to be easily mounted and secured to the tubular body, and allowing the end ring to be reversible in relation to the tubular body.
Claims37
A tube on which yarn is wound to form a yarn pack, comprising:
- a tubular body extending lengthwise between opposed ends thereof and having an outer surface defining an outer diameter of the body, the body having a reduced diameter portion extending lengthwise from at least one end of the body partway toward the other end so as to define a generally radially extending shoulder;
- and
- a press-fit end ring having opposite end faces and being operable to releaseably engage the at least one end of the body proximate the shoulder, the end ring having an inner diameter adapted to mate with the reduced diameter portion of the body, the end ring defining at least two recesses in at least one of the end faces thereof, the at least two recesses and the shoulder forming a plurality of start-up regions for capturing yarn therebetween.
A tube on which yarn is wound to form a yarn pack, comprising:
- a tubular body extending lengthwise between opposed ends thereof and having an outer surface defining an outer diameter of the body, the body having a reduced diameter portion extending lengthwise from at least one end of the body partway toward the other end so as to define a generally radially extending shoulder;
- and
- a removable and replaceable end ring having opposite end faces and being operable to releaseably engage the at least one end of the body proximate the shoulder, the end ring having an inner diameter adapted to mate with the reduced diameter portion of the body, the end ring defining two recesses in each of the end faces thereof, the recesses defined by each of the end faces being spaced apart by at least about 90 degrees, wherein the shoulder and the two recesses of one of the end faces form a plurality of start-up regions for capturing yarn.
A method for winding yarn about a tube for supporting a yarn pack, comprising:
- providing a tubular body having a reduced diameter portion on at least one end thereof such that a radially extending shoulder is defined at an outer surface of the body;
- releasably securing an end ring defining at least two recesses on a first end face thereof to the tubular body so that start-up regions are defined between the recesses and the shoulder of the tubular body;
- removing the end ring from the tubular body;
- reversing the end ring relative to the tubular body;
- releasably securing the end ring to the tubular body so that at least two start-up regions are formed between at least two recesses defined by a second end face of the end ring and the shoulder of the tubular body;
- and
- winding yarn about the tube such that the yarn is captured in at least one of the start-up regions.
