In Great Britain July 24, 1944 3 Claims. (01. 242-43) This invention relates to the means by which yarn is cross traversed whilst being wound on to a yarn package which is peripherally driven so as to maintain a un form yarn speed.
Such traversing may be effected by reciprocatory or rotary guides, The object of the present invention is to provide an improved arrangement of rotary guiding means for cones and cheeses which can be readily and economically produced and is easily threaded up.
The invention comprises the arrangement of two inter-geared parallel rollers spaced a short distance apart, the yarn package being driven by one roller which has therein a single helical groove which extends sufiicientiy to give the yarn the full length of traverse desired and turns back for a short distance at both ends so that such groove serves to lay the yarn on the package at both reversals and also' in one direction of trav-' erse between such reversals, whilst the other and front roller has a spiral groove therein which serves only to traverse the yarn'between reversals in the other direction of traverse.
The invention further comprises the arrangement in which the two rollers are inter-geared to travel in opposite circular directions, the yarn being laid across the two rollers,
The invention further comprises the arrangement of the groove in the back roller of a width suflicient to effect pck-up of yarn laid across the two rollers, such groove hav ng a splayed end where it picks up the yarn from the groove in the front roller, the latter groove having a splayed end where it picks up from the groove in the back roller.
Referring to the accompanying explanatory drawings:
Figure 1 shows two pairs of the yarn traversing rollers with the yarn package, which is being wound, in contact with the back roller of each pair. each pair of rollers to aid the explanation of the yarn traversing operation.
Figure 2 shows the pair of yarn traversing rollers and the yarn package, with the yarn in a different position from any shown in Fgure 1.
Figure 3 is an end view of the left hand pair of rollers in' Figure 1 looking from right to left and showing the path of the two yarns A and B in Figure .1. r
Figure 4 is an end view of the right hand Pair of rollers in Figure 1 looking from left to right and showing the path of the yarns E and F in Figure 1.
The yarn is shown in three positions on v Figure 5 is a lay-out of the complete yarn traversing groove in the back roller.
Figure 6 is a lay-out of the complete yarn traversing groove in the front roller.
4; indicates the front rollers and b the back rollers. Such rollers are secured upon parallel shafts c and d which are geared together by gears e so that the rollers revolve in opposite circular directions and are spaced a short distance apart (see Figures 3 and 4). 1 indicates the conical packages on which the yarn is being wound, the packages being driven by contact with the back rollers b.
The yarn traversing groove 9 in each front roller a does not extend the full length of the roller and is splayed out. at its end 'h where it picks up the yarn from the groove in the back roller. Each groove g serves only for traversing the yarn between the ends of the yarn traversing groove 9' in the cooperating back roller 1). The ends of each groove come gradually to the surface of the roller as will be understood by reference to Figures 3 and 4. Except at its end h, each groove 9 does not act to pick up yarn which may be laid across the pair of rollers, so that the grooves g are relatively narrow. Pick-up is effected by the grooves a in the back rollers and these are therefore relatively much broader than the grooves 9. As each groove 1' picks up the yarn from its cooperating groove 9 at one end only, this end which is lettered k is splayed out.
It will be noted that each yarn traversing groove gives the yarn a complete traverse and also reverses the yarn traverse at each end, whilst the front roller grooves 9 only traverse the yarn from one-end to the other of the grooves in the front rollers.
Yarn A in Figure 1 is just being picked up by the splayed end h of the groove g in the front roller and withdrawn from the groove 1 in the back roller. At B the yarn is being traversed by the groove g in the front roller and is riding on the peripheral surface of the back roller. At
C the yarn is still being guided and traversed by the groove g in the front roller and is upon the peripheral surface of the rear roller. At 0,
Figure 2, the splayed end k of the groove 1 in the back roller is commencing to pick-up the yarn as the groove g in the front roller is completing its traverse of the yarn. At F in Figure 1, the yarn is leaving the groove g and being taken over by the back groove :i which completes the traverse of the yarn to the left. ,At E the yarn is being traversed by the groove 1 and is riding on the peripheral surface of the front roller.- At D the groove i still has control of and is traversing the yarn. From the D position the yarn moves to the A position and the cycle is repeated.
It will be noted that when the yarn is riding upon the peripheral surface of either the front 'or the back rollers it is moving across the groove in such roller ata considerable angle thereto so that there is no tendency for the yarn to drop into the groove in the roller.
To thread the yarns into the traversing grooves, they are simply laid across the rollers, when the broad groove in the back roller'of each pair will pick up the yarn which drops into the groove and is then traversed back and forth as before explained. 1 7
It will be seen that the yarn is always traversed in one direction only by the front grooves g, and that likewise the yarn is traversed in one direction between the ends of each back; groove.
It will be noted from the figures that the grooves g and j are made with constantly increasing pitch from end to' endof the rollers,
both in the same direction, to give accelerated traverse towards one end of the yarn package, which is necessary for winding conical packages.
It will be noted that the upper surface of the front rollers a turn towards the operator whilst the corresponding surface of the back rollers turns away from the operator in front of the machine. This ensures safety to the operator.
In accordance with usual practice in yarn winding, means may be provided for ensuring that the harmony of motion of the yarn package and back roller is broken at intervals to prevent pattern winding. I
With my improvement, I find that I can build a cone with very good ends and that I can wind yarns which it has been found diflicult or impossible. to wind so far at the highest speeds obtained with rotary traversing means.
