YARN GUIDE AND STRING-UP APPARATUS Filed June 28, 1960 FIG.I' Fl6.2
INVENTOR JOHN SEYMOUR SENEY ATTORNEY United States Patent 3,il77,31t3 YARN GUIEE AND STREiG-UP AHARATUS John Seymour Seney, fiearord, DeL, assignor to E. E. du Pont de Nemours and @ompany, Wilmington, Bah, a corporation of Delaware Filed June 23, 196%, Ser. No. 39,379 9 Claims. ((3. 242-47499) This invention relates to the heat-treating and drying of moving yarns and particularly to a novel device for positioning a moving yarn line around the hot rolls used in uch a process.
Yarn is used to designate any artificial or natural monoiilament, multifilarnent, spun staple yarn, or the like.
The positioning or stringing up of a plurality of turns fast-rnoving yarn over and around a plurality of heated high speed rotating rolls is a hazardous and intricate operation. The operator normally manipulates a pair of sticks to perform this operation with the danger of harming himself or the equipment if the sticks should catch in the moving thread. While the remainder of the system can be strung-up at low speed or with the machine stopped, yarn should not be put on the hot rolls unless the yarn is moving at the normal machine speed. Otherwise the yarn will be damaged by excessive heat transfer. In particular, with synthetic yarns the yarn will soften and melt and stick to the rolls.
A principal object of this invention is to provide a safe method and apparatus for effectively stringing up moving yarn on continuous-type heating or drying rolls while the machines are in operation.
Another object of this invention is to provide a simple, reliable, and economical improved arrangement for stringing up yarn around the ends of continuous rotating shaft or shafts.
Other objects of this invention will become apparent when considered with the descriptions as illustrated by the accompanying drawings.
In general, the objects of this invention are accomplished by providing a combined guide and yarn stringup assembly which normally is maintained in a fixed position but which can be moved manually and used to guide the moving yarn around the ends of rotating rolls. The method of stringup around the ends of rotating hot rolls consists of threading yarn through the guide, initially bypassing the rotating rolls, feeding the yarn through the remainder of the system, bringing the system up to running speed, removing the guide from its holder, and using it as a tool to stringup the yarn around the rolls, and replacing the guide in its holder for its normal guiding operation.
The combination guide and string-up tool will be explained more fully in the specification which follows, reference being bad to the accompanying drawings, wherein:
FIGURE 1 is a schematic diagram of a portion of yarn treating system embodying featuresof this invention in which the yarn being heated on the rolls is in position around the rolls, i.e. completely string up.
FIGURE 2 is a view of the same portion of the system of FIGURE 1 in which the yarn is shown partially in position or strung up; and
FlGURE 3 is a longitudinal cross sectional view of the combination hand tool and guide device of the present invention.
FIGURE 1 shows the yarn position and path of move ment under normal operating conditions. Yarn 10 enters the hot roll section of the system through a stationary guide 12, through the combination guide and stringup tool 14, around rotating rolls 16 and 18 in figure 8 configuration. The number of turns around these 3,fi?'i,3f.3 Eatzented Feb. 12, 1%63 ice rolls depends upon the process conditions; ranging from one to a number of wraps around such rolls; and the yarn finally passes to an exhaust system 29 which carries the yarn to other parts of this process. Rolls 16 and 18 are heated by means not shown which can be either internally or externally radiant heaters. The location of guide 14 and exhaust system 2% determine the ac ual location of the wraps around hot rolls to and 13.
FIGURE 2 shows the system with the yarn partially strung up. The yarn is passed through guide 12 and then through the combination guide and string-up tool 14 and directed to the yarn removal device 2i}. During initial starting windup when the system is strung up by hand the temperature of the hot rolls is such that the yarn must be moving when it is in contact with the hot rolls to and 18. It the yarn remains in contact with the rolls, particularly with synthetic yarns, there is a tendency to soften and melt and stick to the rolis. Consequently, the yarn removal device, and the mechanism beyond that, is strung up at low speed. After the stringup is complete, except for the hot rolls, the machine is brought up to opera-ting speed. At that time, the yarn passes as shown in FIGURE 2 with yarn 1% now moving at a high linear speed. The operator removes the cornbination guide and string-up tool 14 from its holder 24-. The string-up tool 14 is of such a size that it will easily fit into the hand of the operator. The operator then takes the hand tool 14 and directs the moving yarn, first under moving roll 16, then over roll 18, around and under roll 18, and finally over roll 16. He makes the necessary number of wraps and then he places the string-up tool in its holder 24 such that it new functions as a guide and positions the yarn it) as it enters onto heated roll 16.
FIGURE 3 shows one embodiment of this combination guide and string-up tool 14. The: assembly consists of an elongated tubular structure 26, preferably made of some suitable material such as aluminum, and two eyelet guide elements 28 and 30, usually made from a suitable wear resistant material. The assembly is made, for example, by forming the tube 26 appropriately at the ends so that the eyelet guides 28 and 30 are frictionally secured in tube 26. Eyelet 28 has the same outside diameter as tube 25- so that it can easily be inserted into the tool holder structure 24. Eyelet 39 has a radial projection so that tool 14 does not slide through the holder structure 24. The assembly is of such a size and weight as to be easily grasped and manipulated by one hand.
By my invention, I have provided a very simple, reliable, and safe arrangement for positioning a running yarn line around one or more rolls with a minimum of time and effort. In addition to serving as a stationary guide for the moving yarn after string-up the novel assembly is ready for instant operation as desired.
-While the precise construction hereinbefore described is preferred, it is understood that the construction or" this combination guide and string-up tool 14 can be modified in a number of ways. Another embodiment may be to have the eyelet guides inserted in such a manner that they are held in either by set screws or appropriate cement. Other modifications within the spirit of this invention will become apparent from the foregoing detailed description and the invention is to be limited only to the extent indicated in the following patent claims.
