Definitions
- This invention relates to draw twisting and more particularly to an improved starting wheel of entrainment disc for a draw twister of the type that is used in the draw twisting of nylon.
- Draw twisting is the expression used in the textile arts to describe a combined twisting and stretching operation of the type that is commonly performed in the preparation. of nylon.
- the undrawn yarn is, delivered downwardly from a source of supply by a roller to a draw pin, is led over the draw pin to and around a godet operated at a greater peripheral speed than the. delivery roller in order to impose tension on the yarn.
- the yarn After leaving the godet, the yarn is guided into the traveler of a ring twister and is laid up on a pirn by a traversing ring board operated in the conventional manner.
- the imposing of tension between two godets or rollers in the draw twisting operation results in the continuous delivery of drawn yarn.
- the waste between the temporary collecting device and the entrainment device wraps around the entrainment device or is otherwise disposed of. It has become common in the past to remove these entrainment discs from time to time to take off from them the waste that has become v wrapped around them. Some of the waste collected in this unguided condition gets into other parts of the machinery and introduces cleaning problems.
- Figure 1 is a schematic view in elevation showing a typical draw twisting position incorporating the improvement of the present invention
- Figure 2 is a top plan view of an entrainment device according to the present invention.
- Figure 3 is an elevational view of the entrainment device of Figure 2;
- Figure 5 is a fragmentary view in section and in elevation taken on the line 5--5 of Figure 2.
- the numeral 10 designates thread or yarn such as nylon which is being subjected to drawing and collection in twisted form.
- This yarn is led from a source not shown through pigtail guide 11, onto a delivery roller system 12. From the rollers 12 the yarn is led around the draw pin 13 to a godet 14.
- the godet operates at a higher peripheral speed than the rollers 12 so that the yarn 10 running between rollers 12 and godet 14 is subjected to stretch.
- the yarn leaving the godet 14 passes through the guide 15 to a suction type or other temporary collect ing device 16.
- the twister as shown, consists of the conventional ring rail 17, which is reciprocated in the This ring rail incorporates a ring for eachv spindle, the ring 18 shown in Figure 1 serving the spindle H.
- the ring 38 is provided with a traveler 20 for guiding the yarn onto the pirn 21 which is removably mounted onto and adapted to be driven by the spindle 19.
- the spindle 19 is caused to rotate from a sheave 22, driven by a belt not shown.
- entrainment disc or starting wheel of the present invention is located around the spindle 19 below the pirn 21 and above the sheave 22.. It: is generally identified by reference numeral 23.
- a cutting knife 24 may belocated between the pneumatic collecting device 16 and that starting device 23.
- the starting device of the present invention is essentially annular and consists of a cylindrical wall 25 having an upper flange 26 and a lower flange 27 both integral.
- the upper and lower flanges both have six notches cut therein as indicated at 28. These notches are arranged in pairs along a chord, the chords being apart. Each notch extends through the flange and just a little into the body 25 to make a groove therein as at 29.
- the notches on the upper and lower flanges are in axial registry and the body groove at 29 connects the bottom of the two axially spaced notches, see Figure 2.
- the yarn is threaded through the delivery rollers 12 and the godet 14 over the pin 13, through the guide 15, ring 18 and into the pneumatic take-up device 16. While the yarn is running between the guide 15 and the take-up device 16, the operator slips it through the traveler 20 so that it may be guided thereby. He then starts the twister spindle 19 rotating and presses the thread 10 running between the traveler 20 and the pneumatic collecting device 16 into one of the notches at 28 in the starting wheel 23. Rotation of the starting device causes the yarn to enter the notch and to wind around the cylindrical body 25. With a light denier yarn the rotation of the starting wheel will cause the yarn running between the pneumatic collecting device 16 and the starting device to break.
- the yarn With heavier denier yarns it may be necessary to cut the yarn as, for example, by the knife indicated at 24 which may be stationary in the path of the yarn or wielded manually by an operator. Once the yarn breaks between the collecting device 16 and the starting wheel 23, the yarn forthwith runs onto the pirn 21 from the traveler 20.
- the starting Wheel of the present invention is provided with a group of notches arranged in a plurality of pairs along an equal number of chords, with the mouth of one notch facing in a direction opposite to the mouth of a complementary notch of each pair whereby the starting disc can function equally well irrespective of the direction of the twist being imparted to the thread.
- a cylindrical surface in between two flanges there is provided a space for the collection of waste which keeps this waste in a position Where it need not be removed ordinarily at the end of every dofling period Where it does 'not interfere with working parts of the machinery.
- a drawtwisting assembly including a driven vertical spindle, a starting wheel mounted on said spindle and adapted to be driven thereby and a pirn removably mounted on said spindle above said wheel, said starting wheel comprisinga-cylindrical body, an upper flange extending radially from one end of said body and a lower flange extending radially from the opposite end of said body, one of said' flanges having at least one pair of notches arranged along a chord with the mouths of complementary notches facing in opposite directions.
- each of said flanges has at least one pair of notches and wherein axial grooves are provided in the outer surface of said body, each of said axial grooves intersecting a notch in both the upper and lower flanges.
- a drawtwisting assembly including a driven vertical spindle, a starting wheel mounted on said spindle and adapted to be driven thereby and a pirn removably mounted on said spindle above said wheel, said starting Wheel comprising a cylindrical body, an upper flange extending radially from one end of said body and a lower flange extending radially from the opposite end of said body, at least one of said flanges having a group of notches arranged in a plurality of pairs along an equal number of chords with complementary notches of each pair facing in opposite directions along a respective chord.
- each of said flanges has a plurality of pairs of notches and wherein axial grooves are provided in the outer surface of said body, each of said axial grooves intersecting a notch in both the upper and lower flanges.
