  • a master drive 21 and a slave drive 22 are respectively fitted within the sample fabrics machine 10 corresponding to positions of the two transmission arms 13 , 14 .
  • the master drive 21 is driven by a power device (such as: a servomotor) (not shown in the drawings), a swing arm 211 is pivotal located to the master drive 21 , and a clutch 23 is located between the power device and the swing arm 211 , thereby enabling the clutch 23 to engage with the swing arm 211 or separate from the swing arm 211 to produce up and down swing or no swing thereof.
  • a power device such as: a servomotor
  • Another swing arm 221 is fitted to the slave drive 22 , and semicircular rows of teeth 213 , 223 are located on corresponding ends of the two swing arms 211 , 221 respectively.
  • the two rows of teeth 213 , 223 are disposed to mutually engage, thus, when the swing arm 211 swings, the other swing arm 221 is actuated and swings in synchronization therewith.
  • the upper end of the transmission arm 13 is pin connected to one side of the lower end of the fixed plate 12
  • the lower end is pin connected to the other end of the swing arm 211 relative to the row of teeth 213
  • the upper end of the other transmission arm 14 is pin connected to the other side of the lower end of the fixed plate 12
  • the lower end is pin connected to the other end of the other swing arm 221 relative to the row of teeth 223 .
  • controlling a portion of the clutches 23 to engage or separate from the swing arms 211 within a period of time causes the two swing arms 211 , 221 to swing or not swing, which then drives a portion of the heald frames 11 to cause up and down swing or no swing thereof through the two transmission arms 13 , 14 within a period of time, thereby weaving the required style of fabric.
  • each of the clutches 23 is connected to the power device, thereby enabling the power device to drive each of the clutches 23 in synchronous rotation.
  • a protruding piece 231 is located on each of the clutches 23

  • a clasp groove 216 is provided on an inner side of the fixed plates 215 to correspond with the protruding pieces 231 , thereby enabling the protruding pieces 231 to insert into the clasp grooves 216 .
  • a selector 15 is located on the sample fabrics machine 10 corresponding to the position of the fixed plate 215 of each of the swing arms 211 , and a push rod 151 is located on each of the selectors 15 above each of the fixed plates 215 .
  • the selectors 15 are electrically connected to a control circuit (not shown in the drawings) of the sample fabrics machine 10 , and the selectors 15 are controlled by the circuit control, thereby enabling the control circuit to control the selectors 15 to extend downward a portion of the push rods 151 within a period of time according to a set program, and thus cause the push rods 151 to actuate and move the fixed plates 215 and induce the protruding pieces 231 of the clutches 23 to separate from the clasp grooves 216 of the fixed plates 215 , thereby causing the clutches 23 to run idle and be unable to drive the swing arms 211 and effect up and down swing thereof, which causes the swing arms 211 to stop swinging within that period of time, and simultaneously suspends up and down swinging of the corresponding heald frames 11 . Accordingly, controlling suspension of up and down swinging of a portion of the heald frames 11 is used to enable the required fabric to be woven.
  • the up-and-down swing mechanism for separated heald frames of a sample fabrics machine of the present invention is assuredly provided with an innovative structure not found in the prior art. Moreover, no similar products have been seen in any publication or in the market; the present invention is thus provided with undoubted originality. In addition, the present invention is provided with unique characteristics and functionality that are without comparison in the prior art. Hence, the incomparable advancement of the present invention clearly complies with the essential elements as required for a new patent application. Accordingly, a new patent application is proposed herein.
