Definitions

  • Such a device is for example known from EP 414 291 A1 and serves to hold a shaft end of a warp beam or a cloth beam in a weaving machine so that it may be installed in the weaving machine or removed from the weaving machine without great difficulty.
  • a disadvantage of such a device is that it comprises a relatively bulky and expensive mechanism for the movable clamping element.
  • the distance between a pivot of the lever and a contact point, in which the running surface of the arm contacts the running surface of the lever in order to reach the holding position is larger than a tangential distance between the pivot and the running surface of the arm, so that the running surface of the arm and the running surface of the lever cooperate to form an over-center mechanism.
  • the device 1 also comprises a spring 20 that may connect the arm 10 and the lever 15.
  • the spring 20 can force the arm 10 and the lever 15 towards one another.
  • the spring 20 may be embodied by a spring system or spring element and consists of a tension spring in the embodiment shown.
  • the spring 20 is hereby installed between an element 21, for example a bolt, attached to the arm 10 and an element 22, for example a bolt, attached to the lever 15.
  • the lever 15 has a stop 23 that may interact with a stop 24 on the arm 10.
  • the stop 23 and the stop 24 are intended to contact one another in the holding position.
  • the relative positions of the bearing element 6 and the bearing element 7 in the holding position may be regulated by making use of the play in the bolt connections 13 with which the bearing element 7 is attached with respect to the arm 10.
  • the lever arm 25 may form an angle with the support surface 4 to allow to guide a shaft end 5 between the lever arm 25 and the support surface 4 towards the bearing 3.
  • the device according to the invention may be applied in different types of machines, such as textile machines, in particular in any type of weaving machine or similar textile machine comprising a part designed to be held at the shaft ends such as a warp beam or a cloth beam.
  • This may be either an airjet weaving machine, a rapier weaving machine, a water jet weaving machine, a projectile weaving machine, some other type of weaving machine, a beaming machine, a knitting machine or some other type of textile machine.
