Passage Of Warp Yarn Through Plain Power Loom? Describe in detail

-
 Here's a detailed explanation of the passage of warp yarn through a plain power loom for your assignment: Passage of Warp Yarn Through a Plain Power Loom The path of the warp yarn through a plain power loom involves several steps, as detailed below: 1. Weaver's Beam: The warp yarn is wound onto the weaver's beam, which serves as the main supply of warp threads for weaving. The beam ensures consistent tension and alignment of the threads. 2. Back Rest: The warp threads pass over the back rest, which helps in guiding the threads and maintaining even tension. It also provides a smooth flow of the yarns during the weaving process. 3. Lease Rods: The lease rods help in separating and organizing the warp threads. They ensure that the threads remain in their correct order and spacing as they pass through the loom. 4. Healds (Heald Shafts): The warp threads pass through the healds, which are thin wires or cords with an eye (hole) in the middle. The healds are mounted on heald shaf...

What is an ARN (Acquirer Reference Number) ? How to trace refund from ARN number | ARN NUMBER| Check refund status from ARN Number

-
What is an ARN (Acquirer Reference Number)? Acquirer Reference Numbers (ARNs) are unique 23-digit numbers. They are linked to online Visa and Mastercard debit and credit card transactions between a merchant’s bank (the acquiring bank) and a cardholder’s bank (the issuing bank). An ARN is created when a transaction flow takes place via a payment gateway. The reference numbers instill confidence in online payments because transactions can be traced and verified as they move through payment flows. What are ARNs used for? By creating more transparency, ARNs help to prevent fraud and unauthorized transactions. They give buyers a better online buying experience and the same reassurances that they would receive when making offline purchases. The unique acquirer reference number means a transaction can be tracked and checked in order to reveal any errors or irregularities. This is useful as refund transactions can take time to process so having insight into what is happening during this proces...

Hopper Bale Opener? What is Hopper Bale Opener machine ? Introduction of Hopper Bale Opener

-
 Here are the definitions of each part of the Bale Breaker Machine along with their functions: Hopper Bale Opener:— A hopper bale opener is a machine that opens cotton bales and mixes the fibers. It's used in the textile industry to prepare cotton for spinning.  1. Creeper Lattice (First Conveyor Belt) It is the initial conveyor belt in the system. It transfers the fed material (cotton fiber bales) to the next conveyor belt, which is the feed lattice. 2. Feed Lattice (Bottom Lattice) Also known as the bottom lattice because it starts at the lower end of the creeper lattice. It moves the material from the creeper lattice to the inclined lattice. It operates at a relatively higher speed to ensure smooth material flow. 3. Inclined Lattice (Spikes Lattice) This is also called the spikes lattice as it has metallic pins (spikes) on its surface. These spikes grab the fiber tufts from the feed lattice and transport them to a higher level in the machine. 4. Even Roller It is positioned...
