Definitions

  • ABSTRACT A strand carrier for a high-speed maypole braiding machine, in which the strand pay-off point of each strand carrier is maintained in substantially the same orientation relatively to the braiding point during the travel of the carrier in its serpentine path around the braiding point.
  • the strand carrier of the instant invention is of a construction providing for an increased capacity of the strand supply and includes a hinged upper section normally overlying the strand supply but which may be readily swung open to permit the replenishment of the supply, the hinged upper section incorporating a slack take-up and strand-tensioning means, means for normally preventing rotation of the strand supply bobbin relatively to the carrier, and means under the control of the strand take-up and tensioning means for releasing the bobbin for rotation in a strand pay-off direction when an additional length of the strand is required in the braiding operation.
  • BRAIDER CARRIER BACKGROUND OF THE INVENTION 1 Field of the Invention Conventionally in strand carriers for braiding machines, the strand material is wound on bobbins rotatably mounted on the carriers and the bobbins are alternately held against rotation to provide tension in the strand material and released under the control of tension members to permit the withdrawal of the strand material as the carriers are propelled along their serpentine paths about the braiding point of the machine.
  • the present invention is directedto abrander carrier, particularly adapted. for employment in a braiding machine of Applicants said prior application although it may be used in. braiding machines of other types, in which the slack take-up and strand-tensioning means and other strand. control elements are readily removably mounted above the bobbin whereby maximum space is provided. for the bobbin with consequent increased strand-carrying capacity andother advantages are attained, as will become apparent hereinafter.
  • the strand-tensioning means again is, in part, mounted above the strand supply bobbin and provision is made for the removal of such mechanism when the strand supply is to be renewed.
  • the strand take-up and tensioning means additionally re quire the inclusion of a torsion spring located interiorly of the carrier with the result that the strand-carrying capacity of the bobbin is compromised or substantially limited.
  • An associated strand-clamping mechanism of which there is no counterpart in the carrier of the instant invention, is also required.
  • the principal object of the instant invention is the provision of a strand carrier of an improved construction for employment in a high-speed braiding machine of the maypole type and particularly in a braiding machine incorporating the features of Applicants said prior application Ser. No. 280,631.
  • Another object of the invention is the provision of a braider carrier attaining the foregoing object having a maximum strand-carrying capacity.
  • a further object of the invention is the provision of a braider carrier attaining the foregoing objects which additionally includes improved and simplified means for compensating for or taking up the slack in the braiding strand and applying substantially uniform tension thereto as the carrier moves in its sinuous or serpentine path around the braiding point.
  • a still further object of the invention is the provision of a braider carrier attaining the foregoing objects in which the mass of the mechanism serving to take up or compensate for the slack which would otherwise occur in the strand and for tensioning the strand is substan' tially reduce as compared to the mechanism accomplishing similar functions in prior carriers.
  • the carrier may be employed without modification in braiders inwhich the braider deck is in either a vertical, horizontal or intermediate plane.
  • the braider deck is in a horizontal plane with the carriers positioned thereabove.
  • the braider carrier of the invention comprises a would otherwise occur at intervals in the braiding strand as the carrier travels in its serpentine path around the braiding point and for applying substantially uniform tension to the strand during such travel.
  • the preferred means employed to perform the above-mentioned functions comprises an arm (herein termed a compensator arm) pivotally mounted at the longitudinal center thereof, and with the pivot point in axial alignment with the bobbin-supporting spindle, on a frame member overlying the yarn supply bobbin, the arm having sheaves affixed adjacent the opposite ends thereof for guiding the strands in what is here termed an S or Z path.
  • the compensator arm is urged to rotate in a direction to tension the strand by a torsion spring having associated means to adjust the torque exerted thereby.
  • the bobbin carrying the strand supply is normally held against rotation as by a clutch mechanism which is released at times, under the influence of the compensator arm, to permit pay-off of the strand from the bobbin when an additional length of the strand is required for the braiding operation.
  • the frame member referred to above which supports the compensator arm and which also supports the torsion spring and the clutch mechanism comprises a hub element which is hingedly connected to a fixed vertically-extending post forming a portion of the carrier frame. This construction permits the ready removal or swinging out of the strand-tensioning and controlling elements when a bobbin is to be replaced.
  • the advantageous features of the construction include the ability to maintain the mass of the compensator arm at a minimum, thereby permitting high speeds to be employed. Also, the advantageous features include the ease with which the strand may be threaded and the elimination of the customary braking or sliding elements and the necessity of a pay-out eye or swivel device. The construction also affords ample space for an appropriately large torsion spring which reduces tension variation in the strand, as it is fed to the braiding point, to a minimum.
  • a substantial field of use of the carrier of the invention is in braiding machines of the type employed for the reinforcement of high pressure hose and the like with metallic strands.
  • its field of use is not so limited as the carrier may be equally well employed in the production of other braided products such as, for example, those composed of textile or other nonmetallic strands.
  • the provision of means, previously mentioned, to adjust the force or torque exerted on the compensator arm by the torsion spring is of critical importance as it permits the tension imparted to the strand to be selected as required by the particular strand material employed or the product to be produced.
