Weaving

   •“A textile craft in which two distinct sets of yarns or
   threads are interlaced to form a fabric or cloth. The threads
   which run lengthways are called the warp and the threads which
   run across from side to side are the weft or filling.”

Accumulator Setting:
Electronic head of Accumulator has one ON/OFF switch & 4
settings are there,
1. Setting of winding Speed by a set screw.
2. Intensity of photocell can be changed according to type of weft
yarn Texture or spun.
3. Amount of yarn wound on winding head by altering the position
of photocell by the help of rotating screw arranged with Rack-
Pinion system.
4. NT / RT setting

Technical specifications of P 7100 weaving machines:
  The machine handles practically all types of yarns: spun yarn,
  filament yarn, fancy yarn etc.
  In the weft the machine processes staple fiber yarns from Nm
  0.5-160 and continuous filament yarns from 5000-10.8 denier.
  Weft density is between 0.83-181.5 picks/cm. Maximum weft
  insertion rate 1200 meter / min. and speed upto 400 rpm.
  Can work for upto four different weft colours.
  Nominal width 190-540 cm.
  Machine design is extremely compact.

Light signals in use:
  Blue light blinking: warp thread breakage.
  Yellow light blinking: weft threads breakage.
  Yellow and red light blinking: shut down via emergency switch.
  Red light: mechanical fault.
  Red light blinking when machine is working: electronic
  projectile detector or weft detector switched off.

Sensors and stop motion:
  Projectile sensor: It is a metallic sensor situated at the receiving
  side and it senses that projectile is reaching at correct angle or not.
  Let – off sensor: P7100 provides electronic let off. If tension in
  warp sheet decreases the sensor senses it by suitable arrangement
  and motor regulates warp sheet accordingly
  Weft sensor: To sense the presence and absence of weft supply at
  receiving side.
  Angle sensor: To stop the loom at correct angle at particular
  degree
  Warp stop motion: Electrical warp stop motion work together
  with drop pin attachments

  • 8. Weaving Light signals in use: Blue light blinking: warp thread breakage. Yellow light blinking: weft threads breakage. Yellow and red light blinking: shut down via emergency switch. Red light: mechanical fault. Red light blinking when machine is working: electronic projectile detector or weft detector switched off.

  • 9. Weaving Sensors and stop motion: Projectile sensor: It is a metallic sensor situated at the receiving side and it senses that projectile is reaching at correct angle or not. Let – off sensor: P7100 provides electronic let off. If tension in warp sheet decreases the sensor senses it by suitable arrangement and motor regulates warp sheet accordingly Weft sensor: To sense the presence and absence of weft supply at receiving side. Angle sensor: To stop the loom at correct angle at particular degree Warp stop motion: Electrical warp stop motion work together with drop pin attachments Sunday, October 23, 2011 TEXTILE INTERNSHIP- DILIP SINGH, KUMAR SARVESH, PRASHANT GAURAV & RAJEEV SHARAN/ DFT-05/ NIFT BANGALORE
