Definitions

  • the present invention relates to a device for the knotless joining of thread ends, said device being operated with compressed gas and including a resonance surface opposite a gas nozzle.
  • Devices are presently known for the manufacture of so-called tangled yarns. These devices consist mainly of a compressed gas nozzle and a resonance surface opposite the nozzle month. These devices have also been used to connect yarn ends. The two yarn ends are laid side by side in a thread guide and held undera slight preselected tension. Air is then blown onto the threads for a short time to produce the connection.
  • these devices were primarily designed in the manufacture of tangled yarns, they are not adequately equipped for the joining of yarn ends. Consequently, the production of such joints was time consuming and inconvenient and often not possible at all because the devices are solidly mounted and are difiicult to work on. Likewise, these machines lacked a positive clamping of the thread ends which is required to assure a satisfactory joint.
  • the subject invention involves the discovery of a device which can be used to join thread ends by twisting with the help of a gas stream.
  • the success of the device flowed from the discovery of an arrangement wherein a piston operating against a spring is arranged between a gas pressure valve and a generally known air nozzle, which nozzle is located opposite a resonance surface.
  • the piston lies within a cylinder which is preferably set up parallel to the air nozzle axis.
  • the distance between the air nozzle and the resonance surface is adjustable because both parts can be shifted in either direction along a common axis.
  • the piston acts upon clamping means which include two U-shaped enclosures or covers which limit the air zone.
  • the clamping device features clamping points lined by an elastic material at the level of notched guides of lateral covering sheets for the air zone, which guides support the two thread ends.
  • the dimen- 3,345,809 Patented Oct. 10, 1967 sions of the piston and spring are selected in such a way that first of all the clamping becomes effective and then the effective air pressure builds up. Due to the lining with the elastic material, the secure holding of the thread ends is guaranteed.
  • FIGURE 1 is a sectional view of a device of the invention which is in the form of a pistol;
  • FIGURE 2 is a perspective view of the device with some parts cut away to show underlying mechanisms.
  • compressed gas line 2 is shown screwed into insert 33 in handle or base portion of device 1.
  • Valve 3 which operates against spring 4 blocks air channel 6 which leads from gas line 2 to air nozzle 17.
  • Air channel 6 is opened by pressing against trigger or button 5;
  • Piston 7 acting against spring 8 is mounted in cylinder 34 below air nozzle 17, said piston acting upon shaft 10 via piston rod 9 in the manner described more fully below.
  • nozzle 17 and resonance surface 18 are mounted in two coaxial bores in the housing of the device. Cut-out or relief 31 lies between the nozzle and the resonance surface. The nozzle and the resonance surface are held in place by set screws 23 and 25.
  • the nozzle itself consists of a cylindrical body which is slidably mounted within one of said bores. Bore 20 of the nozzle and the extended opening 19 into said bore permits the entry of air from channel 6 at every longitudinal position at which the nozzle might be placed for adjustment purposes.
  • the nozzle opening or muzzle is identified by numeral 21.
  • the resonance surface 18 is of well known construction and is mounted on cylindrical insert 24 which, in turn, is .movably mounted within device 1. The insert and the resonance surface can be fixed in place by means of set screw 25.
  • Covers or side panels 28 which can be constructed of sheet metal are mounted at both sides of cut-out or relief 31. These covers include scores or notched guides 32 which serve as support for the thread ends to be joined.
  • Two side panels 11 and 12 are connected by means of upper plates or panels 29 and 30 to form U-shaped enclosures or covers. These covers are rotatably mounted on shafts 13 and 14.
  • a pin 15 can be inserted into both side panels 12 of one cover 12-30 which pins gear into a corresponding slot in the panel parts 11 of the second cover or enclosure 11-29 to provide a coacting movement between the two parts.
  • the two covers 11-29 and 12-30 are adjusted so that when swung together, scores or guide notches 32 line up with the thread contact points of panels 11 and 12, preferably in the center of cut-outer relief 31.
  • the coaction between the two covers 11-29 and 12-30 present can be produced in another manner such as through the use of a cam or meshing gears.
  • side panels 11 and 12 include semicircular openings at the height of the notched guides 32. Inserts 16 consisting of rubber or similar material are placed in said semicircular cut-outs. Inserts 16 clamp to thread ends in such a manner that a line through the base of the two notched guides 32 runs through the center of the contact surface of the insert.
  • the device In operation, after nozzle 17 and resonance surface 18 have been adjusted in a known manner such that the introduction of the compressed air has the desired effect of twisting and joining the thread ends, the device is ready for operation.
  • trigger or button When trigger or button is pressed, the passage for the gas from line 2 to nozzle 20 is opened. Simultaneously, piston 7 is acted upon by the compressed air and is moved in cylinder 34 against the force of spring 8;, The movement of piston 7 causes covers 11-29 and 12 -30 to move together. This assures a positive clamping of the thread ends and also closes off the blow zone to the outside.
  • valve 3 and passage 6 should allow a full function of the nozzle but, on the other hand, be tight enough to prevent a rapid pressure build-up behind the valve.
  • the working pressure of the blow nozzle preferably lies between 1.5 and 10, and more preferably between 2.5 and 6 kg./cm. above atmospheric pressure.
  • the present device can be used with success where thread material of one kind is wound into another kind, for instance, for spool and twine machines, the manufacture of weft bobbins, etc., and also for the processing of thread on weaving and knitting machin%.
  • the device can be mounted in place or can be hand-carried.
  • a handcarried device of the present invention is of advantage for spool and twine machines. In other cases such as in the manufacture of weft bobbins, etc., it may be of advantage to install a device according to the present invention as a fixed part of the machine.
  • a device according to this invention can especially be used to advantage where stationary knot devices or automatic knot tying devices were previously in use.
  • a thread joint as produced by a device according to this invention has the same characteristics as the thread material itself and does not require special attention in processing. It is now possible to produce thread of any length.
  • a stationary device can be used for an automated joinings of threads.
  • the ends that have to be joined can, for example, be held by claws as known on the automatic knot tying machines and be laid into the device according to this invention.
  • a corresponding electrical circuit which, for example, can be actuated by the claws can be initiated by a limit switch.
  • Joints produced by a device according to this invention feature the same tensile strength as the yarn itself.
  • the thicker thread portion is hardly noticeable and runs through all devices like thread guides, knitting needle eyes, etc., without any problems.
  • Of special importance is the fact that the joints are not noticeable in texturing processing such as upsetting, etc., and cannot be noticed after a dyeing process.
  • Valve 3 shown in the drawing can be actuated by a foot pedal if a corresponding lever or pull connection is used. This can be of advantage when a rigidly mounted device according to this invention is used, or this can be accomplished by the actuation of a limit switch by the holding device when an automatic holding device for the thread ends is employed.
  • the switch contact duration can be made adjustable by the use of a time relay. This can control the duration of the device and the following release of the connected thread.
  • An automatic holding device like the one already known for the automatic knot tying machines can also be employed.
  • a device for the knotless connection of thread ends which comprises: a housing for said device; conveying means for conveying gas under pressure to said device; an air nozzle within said device; a resonating surface opposite said nozzle; a valve mounted within said device for controlling the flow of air to said nozzle; a piston acting against a spring and a piston rod mounted within a cylinder, said cylinder being connected to said conveying means at a point between said valve and said nozzle; thread holding means operatively associated with said piston and piston rod; and control means for actuating said thread holding means prior to the build-up of working pressure in said nozzle.
  • said thread holding means is in the form of two U-shaped covers, which covers close off the area between the opening of said nozzle and said resonating surface when said holding means is actuated.
