Claims. (Cl. 57- -60) p This invention relates to machines for the production of tyre cord and like yarn and is an improvement in or modification of the invention described and claimed in my prior United States patent application No. 468,480.
The object of the present invention is to improve the machine of the said prior specification by reducing the overall length of the machine for any particular number of uptwisting and cabling spindles. p I .1
The invention consists in an improyement infer modification of the machine for producing tyre cord or like yarn as claimed in claim 1 of my prior specification No. 468,480 according to which the uptwisting spindles associated with a cabling or doubling spindle in producing a single tyre cord or like yarn are arranged partly in the general line of the doubling or cabling spindles in the machine and partly in front of the other uptwisting spindle or spindles in such line.
The invention further comprises a machine as aforesaid comprising at each side in line two uptwisting spindles, two cabling spindles, two uptwisting spindles followed by repeats of two cabling spindles and two uptwisting spindles and finishing with two uptwister spindles after two cabling spindles, with one uptwister spindle in front but slightly to one side of each uptwister spindle in the line with the exception of the last pair of uptwister spindles at each end of the line.
Referring to the accompanying explanatory drawings:
Figure 1 is a front elevation of parts of a combined uptwisting and ring doubling machine constructed in accordance with the present invention.
Figure 2 is a plan view of Figure 1.
Figure 3 is an end view of the two sides of a machine as shown in Figure 1, the view showing two uptwisting spindles at each side of the machine.
Figure 4 is a plan view showing the drives to four uptwisting spindles at each side of the machine.
Figure 5 is a plan view showing the drive to two ring doubling spindles, one at each side of the machine.
Figure 6 is a front view showing the means for simultaneously braking a ring doubling spindle and its associated two uptwisting spindles.
Figure 7 is a plan view of the braking arrangement shown in Figure 6.
Figure 8 is an end view similar to Figure 3 but showing a doubling spindle at each side of the machine.
The single yarn which may be upon double flanged bobbins a on uptwisting spindles b is uptwisted from the bobbins a so that a certain degree of additional twist is imparted to the yarn, the latter passing through flyers c and lappet guides d around guide pegs e and 7, around delivery rollers g as shown in Figure 8, through lappet guides h, travellers on the rings i and on to the bobbins j on the ring twisting or cabling spindles k.
It will be seen by reference to Figures 1 and 2 that each doubling spindle k cooperates with two uptwisting spindles b, and that one of such pair is not in the general line of the spindles at opposite sides of the machine but Patented May 26, 1959 2 is in front of its cooperating uptwisting spindle but slightly to one side thereof. a
The pegs e and f are mounted on a rod m which is given short reciprocatory movements so that the yarn does not travel continuously in one track on the delivery rollers g but moves slightly backwards and forwards thereon.
The doubling spindles are driven in pairs (one at each side of the machine) as shown in Figures 5 and 8. The shaft 0 which is driven in unison with the shaft p through change speed gearing q (shown in Figure 4) has thereon a series of pulleys q which drive belts r on the wharves of the doubling spindles k. The belts pass over tensioning or jockey pulleys s. Theshaft p has a series of pulleys t thereon which drive the uptwisting spindles b (as shown in Figures 3 and 4) through belts u. It will be seen that each belt u drives four uptwisting spindles b. The four uptwisting spindles b associated with a pair of doubling spindles k at each side of the machine are driven by two belts as shown clearly in Figure 4. v indicates tensioning or jockey pulleys for the belts driving the uptwisting spindles. i
Each doubling spindle k and its associated pair of uptwisting spindles b are adapted to be stopped simultaneously, if necessary due to yarn breakage or other cause, by brakes w mounted in pivoted brake holders x operated from a single foot operated pedal y. Such pedal y is pivoted about a fixed support z and operates a rod 10 which engages at its upper end beneath a three armed member 11, each arm of which has a short vertical rod 12 resting thereon which engages a member 13 adapted when raised to turn the pivoted brake holders x about their pivots 14 and so cause the brake pads w in such holders to engage simultaneously the wharves on the associated uptwisting and doubling spindles.
The speed of the bottom delivery rollers g can be changed to vary the rate of delivery of yarn to the doubling spindle bobbins j to give the required turns per inch in the finished yarn or cord. To obtain the correct turns per inch in the yarn from the uptwisting bobbins a, it is necessary to adjust the speed of the uptwister spindles b relatively to the speed of the doubling spindles k. This is done by the change speed gearing q shown in Figures 3 and 4.
The threading of the yarn is from the uptwister bobbins a through their flyers c, the lappets d round the guide pegs e and through the delivery rollers g, and a lappet h to the usual traveller on the ring i around the doubling bobbin With my present improvement in relation to the inven tion described and claimed in my prior specification No. 468,480, I am enabled to obtain a greater productive capacity in a certain length of machine by arranging one uptwisting spindle b of each pair in front of the other spindle of the pair instead of in line with such other spindle and its associated doubling spindle.
In a complete machine there are in line two uptwisting spindles at one end succeeded by pairs of cabling or doubling spindles and pairs of uptwisting spindles, there being an uptwister spindle in front but slightly to one side of each uptwister spindle in the line with the exception of the last pair of uptwister spindles at each end of the line. This arrangement enables the drives to all the uptwister spindles to be as shown in Figure 4.
If desired three uptwisting spindles may be associated with each doubling spindle, two of such spindles being in line with the doubling spindle and the other uptwisting spindle being in front of the two associated uptwisting spindles.
What I claim is:
1. A machine for producing tire cord and like yarn comprising a plurality of sets of spindles along each side of the machine, each set comprising a least two uptwisting spindles and one cabling spindle, the uptwisting spindles being disposed along each side of the machine partly in the general line of the cabling spindles and partly in front of such line, two cabling spindles being disposed between two uptwisting spindles in said line, a fiyer on each uptwisting spindle for passing the yarn from the bobbin of the spindle, delivery rollers on the machine for feeding the yarn from the flyers, the yarn being united at the delivery side of the rollers, a traveller adjacent a cabling spindle for guiding the united yarn to the bobbin on the cabling spindle and a lappet between the delivery rollers and traveller for guiding the united yarn to the traveller, means driving all the uptwisting spindles in unison and in a direction opposite to the cabling spindle, means varying the speed of the uptwisting spindles and the delivery rollers relative to the cabling spindles to obtain the desired twist in the yarn and further means applying a braking effect simultaneously to each set of uptwisting spindles and its associated cabling spindle.
2. A machine as defined in claim 1 including at each side in line two uptwisting spindles, two cabling spindles, two uptwisting spindles, two cabling spindles followed by repeats of two uptwisting spindles and two cabling spindles and terminating in two uptwisting spindles following two preceding cabling spindles all in line, with an ad '4 ditional uptwisting "spindle in front of and slightly to one side of each uptwisting spindle in the line of spindles at the positions where two uptwisting spindles come between two cabling spindles.
3. In a. machine as claimed in claim 2, means for driving the uptwisting spindles associated with a pair of doubling or cabling spindles at opposite sides of the machine comprising two continuous belts, each belt driving two uptwisting spindles at each opposite side of the machine.
4. A machine as defined in claim 1 including a shaft, pulleys on such shaft to drive all of the cabling spindles, a second shaft, and pulleys on the second shaft to drive all of the uptwisting spindles and change speed gearing through which the uptwisting spindles are driven from the pulleys on the second shaft.
5. A machine as defined in claim 1 including a change speed gearing through which the delivery rollers are driven from the shaft driving the cabling spindles.
