Definitions

  • the invention relates to a device for weft insertion on a belt rapier weaving machine, with a belt wheel driven in an alternating direction of rotation and a flexible entry belt carrying an insertion member for a weft thread, which is attached at one end to the belt wheel and which with winding and unwinding in a more is issued as a 360 ° circumferential wrapping area of the belt wheel of an oscillating movement transversely to the warp threads from or into the shed, as well as with a flexible guide element, which wraps around the part of the entry belt located on the belt wheel and a first section at a distance has a second section running from the entry belt and guided over two deflection rollers arranged at a distance from one another.
  • the guide element is formed by a rope, the two ends of which are each guided through a recess provided in the circumferential region of the band wheel against the axis of the band wheel and are fastened to a tab arranged inside the band wheel body .
  • one end of the entry belt is fastened by a screw to the recess in the unwinding direction of the entry belt.
  • a support section is formed on the circumference of the belt wheel, which has a thickness that is approximately constant over 100 ° of the circumference of the belt wheel and a thickness that is essentially spiral-like over the remaining circumference section and that increases continuously in the unwinding direction, this circumference section in the region of the recess ends with a gradation, the height of which corresponds to the sum of the thicknesses of the rope and the entry tape.
  • kinks can occur in the part of the entry belt that wraps around the clamping end, which lead to permanent deformation of the entry belt and thus the service life and can affect the leadership of the entry belt.
  • the guide element deflected in the area of the recess with a correspondingly small radius is also subjected to particularly high stress.
  • the invention has for its object to provide a particularly improved in this respect device of the type mentioned, which - with a simplified design of the tape wheel - a kink-free guidance of the entry belt when winding the tape wheel through an angle of more than 360 ° and a corresponding gentle Guiding of the guide element also permitted in connection with belt wheels in a compact design.
  • At least one trough-like recess is provided on the circumference of the belt wheel for receiving one end section of the entry belt and / or one end section of the guide element, and that at least one can be fastened in the recess against the relevant end section of the entry belt and / or the guide element clampable clamping piece is provided, which is adapted to the course of the adjoining the depression in both circumferential sections of the surfaces to be wrapped and continuously curved over the depression in the circumferential direction of the support surface for the portion of the entry belt or the guide passed over the depression . of the guide element.
  • the device designed according to the invention permits particularly gentle guidance of the entry belt in a guideway which, from the clamping point arranged in the recess, runs flatly curved against the peripheral surface of the belt wheel. At the same time, when the clamping point is wound over, a secure guidance of the portion of the entry belt extending over the recess and the portion of the guide element which lies against it is ensured.
  • a kink-free run-up of the relevant section of the entry belt onto the transition point between the end section located in the recess and the part of the guide element wrapping around the entry belt or on the unwinding process is correspondingly appropriate kink-free running of the relevant batch of Entry belt can be achieved from the area of the said transition point, since the clamping piece designed and arranged according to the invention, with its arched support surface, prevents "sagging" of the portions of the entry belt and the guide element resting thereon. Accordingly, additional stresses on the material, which is already highly stressed, in particular in connection with the large working widths and high weft insertion rates of today's weaving machines, are avoided.
  • a particularly compact design can be achieved with a tape wheel that can be rewound several times.
  • the entangled arrangement of deflection rollers is known per se in connection with a lateral deflection of a rope-like, cut-off guide element; a lateral deflection of a band-like guide element has so far been avoided in the case of weft insertion devices of the type mentioned at the outset.
  • the design according to claim 2 ensures trouble-free lateral deflection and thus reliable guiding of the cut-off band-like guide element in two adjacent wrap areas of the band wheel.
  • the embodiment according to claim 2 leads in particular to a uniformly over the width of the guide belt wrapping the entry belt distributed, relatively low loads on both the entry belt and the belt wheel, since high local loads, such as can occur when using a rope-like guide element, are eliminated.
  • the belt wheel which has to be stopped and accelerated again each time the direction of rotation changes, can therefore be of a correspondingly light construction, for example made of a plastic, and have a correspondingly low mass.
  • the band-shaped guide element can neither "dig" into the entry belt nor via this into the peripheral surface of the band wheel and can have a much smaller thickness than a rope-like embodiment, so that even with multiple winding of the Band wheel results in a relatively small, alternately accelerating and decelerating moving mass.
  • a tight fit of the generally relatively dimensionally stable entry belt can already be ensured at the transition point between the clamping point and the peripheral region of the belt wheel.
  • the machine frame 1 shows parts of a machine frame 1 and a sley 2 of a belt rapier weaving machine of known construction.

  • the rapier heads 8 are constantly moved along the sley 2 to the middle of the shed and then pulled out of the shed again.
  • One end of a weft thread is transferred from a weft thread supply located on the right side of the weaving machine, not shown, outside the shed to the rapier head arranged on the right entry belt.
  • the weft thread is inserted into the first half of the shed and transferred in the middle of the shed to the rapier head 8 arranged on the left entry belt 7, through which the weft thread is then inserted into the second half of the shed.
