The present invention relates to a compact creel for use normally with tufting machines and more particularly to structures and methods of utilizing a linear stacked yarn roll arrangement which is particularly attractive for at least short length of carpet runs, accent yarns and/or other purposes.
Creels have been in existence most likely since the existence of tufting machines which date back to the early 1960s or before. Tufting machines are the machines that make carpet by directing one or more yarns to specific needles in one or more rows of needles which then proceed through backing to make tufts. Further finishing is often provided before the carpet is sold to a consumer.
In the prior art, a yarn roll would be provided at a specific location on a creel on an arm; one yarn roll per arm. The tail end of that yarn roll would then typically be tied to an adjacent yarn roll so that when the first roll is exhausted, the second roll would begin to be fed to the same needle without interruption. These adjacent yarn cone holders are normally called “bullhorns” because they point towards one another and are directed at the same eye which begins to direct yarn to the appropriate needle. However, the bullhorn style creel construction takes up a good bit of space as sufficient room must be left for the proper feeding from both of the rolls.
The bullhorn construction, while useful in various applications, it is not necessarily best suited for all applications. For instance, if a need exists to provide a compact creel, the bullhorn style construction may not provide sufficient compaction. Other motivations may produce a need for an improved holder for yarn rolls, such as a creel or other devices, as well.
Accordingly, is a present object of many embodiments of the present invention to provide an improved creel construction.
It is another object of many embodiments of the present invention to provide an improved yarn roll feed arrangement.
It is another object of many embodiments of the present invention to provide an improved stacked yarn roll configuration for various applications.
Accordingly, in accordance with at least some presently preferred embodiments of the present invention, at least two yarn cones can be stacked in a linear arrangement on a support, such as an arm, extending from a creel or other structure, most likely pointed toward an eyelet which directs the yarn to a specific needle of a tufting machine. As one can see from the figures, a colinear yarn roll construction could feed rotatably oppositely off their respective cones so that the yarns combine at the eyelet when fed at the same time. As long as the forward yarn cone is the same or smaller size than the rear cone, then this arrangement has been found to work satisfactory when feeding yarn ends from the linearly arranged yarn cones at the same time. Although only two yarn cones are shown, obviously three or more could be mounted in a similar manner.
It is worth observing that on successive cones using this construction, the offtake direction of the yarns can be in opposite directions so that they preferably do not become entangled as they are fed toward the eyelet. Other embodiments may offtake in the same direction, possibly using additional structure before the eyelet.
For these or other embodiments, the yarn cones can be loaded on the same post or arm in a collinear arrangement. Some embodiments, in a collinear arrangement, can direct a single yarn to the eyelet at a time. Specifically, after the front yarn cone is exhausted, instead of the yarn end being tied to a yarn cone at a different lateral location on the creel like is done in prior art, the rearward cone begins feeding at that the same location on the creel just from a rearwardly located yarn cone.
The adjacent yarn cone supports, and not just as it relates to vertically adjacent as is done in the past, but horizontally adjacent supports as well can be linearly disposed instead of angled towards a common eyelet as has been done in the prior art with bullhorn style arrangements. With bullhorn construction, linearly horizontally adjacent yarn cones point at the same eyelet so that after the yarn is pulled off of one cone, it then begins to be pulled off the linearly adjacent one of a bullhorn pair.
While some embodiments of the present invention can accommodate bullhorn style creels, the stacking arrangement as shown and described herein is believed to be novel over prior art constructions and can provide more compact creels for at least some embodiments.
The particular features and advantages of the invention as well as other objects will become apparent from the following description taken in connection with the accompanying drawings in which:
In the prior art, an arm is constructed to hold only a single yarn cone and is not constructed to be of suitable length to hold a second yarn cone (or more) in a colinear arrangement with another yarn cone.
More than two yarn rolls 12,14 might be appropriate for other embodiments. An ability to add a third and successive yarn rolls from the back 13 at detachable connection 21 may assist for some embodiments as yarn may continue to be fed from the front 15 while adding yarn from behind. For example, spent rolls could be removed from the front, the remaining rolls pushed toward the front, and new roll(s) added from the rear. More particularly, the illustrated embodiment shows where the yarns 20,22 are being fed to the same eyelet 28 to then be fed ultimately to the same needle 23 of a tufting machine 25 from the stacked yarn rolls 12,14. In this embodiment one will notice that the direction of feed 30 to the front 15 of the first yarn roll 12 is oppositely directed from the direction of feed 32 of the second yarn roll 14 (i.e. the direction the yarns 20,22 come off the yarn rolls 20,22). The applicants discovered that if they feed in the same direction of feed to the same feed opening or eyelet 28 they tend to sometimes become entangled and create problems during the feeding process. Feed openings could be an eyelet 28, a tube opening and/or other pathway whereby the yarn(s) are fed to a needle 23 of a tufting machine 25. However, by reversing the directions 30,32 relative to one another, then the yarns 20,22 can feed cleanly to the eyelet 20. Other embodiments may be able to proceed in a common direction of feed. Some other embodiments may accommodate more yarn rolls 12,14 in a stacked linear arrangement.
For some applications such as short runs, this construction has advantage over the prior art in that multiple yarns 20,22 can be jointly fed to a single needle (eyelet 28) from a single arm 24 of the creel 10. This can eliminate twisting and/or other joining steps (two yarns or more together) possibly practiced in the prior art.
Still other embodiments may utilize this advanced construction of an arm 24 which is configured to hold at least first and second yarn rolls 12,14 thereon in a secure manner that they both can feed yarns 20,22 toward a single eyelet 28. Specifically this same construction as shown in
As can be seen with reference to
Of course, bullhorn style construction could be utilized with the yarn cone arrangement as shown above for
Numerous alterations of the structure herein disclosed will suggest themselves to those skilled in the art. However, it is to be understood that the present disclosure relates to the preferred embodiment of the invention which is for purposes of illustration only and not to be construed as a limitation of the invention. All such modifications which do not depart from the spirit of the invention are intended to be included within the scope of the appended claims.
