By doing so, it can ensure that the loom has a continuous supply of weft yarns, thus improving weaving efficiency and the quality of the final fabric. The pantograph loom weft accumulator also helps to reduce yarn breakage and other problems during the weaving process, making it an essential part of modern loom technology.
Claw loom weft accumulator:
The claw loom weft accumulator is an important part of a loom. Its main function is to store weft yarns during weaving and release them according to the weaving needs. This ensures an uninterrupted supply of weft yarns, thus improving the efficiency of weaving. The claw loom weft accumulator works by clamping and releasing the weft yarns through the claw mechanism, which accurately controls the amount of weft yarn stored. This function helps to reduce yarn breakage and the defect rate in the weaving process, ensuring the quality of the fabric.
Accumulator roll length & diameter:
Typically, industrial loom weft accumulators have roller lengths of about 1-3 meters and diameters ranging from 0.5 to 1.5 meters. However, specific dimensions can vary depending on the weaving machine and the fabric being produced.
Fabric breadth:
The breadth of the fabric that a loom weft accumulator can accommodate often corresponds to the maximum weaving width of the loom. For example, a loom that weaves wide cotton cloth may have a weft accumulator capable of handling fabric widths of up to 200 cm.
Storage Capacity:
Weft accumulators' storage capacity is generally measured by the length of yarn or the quantity of woven fabric they can hold. Loom weft accumulators in large-scale textile factories may have a storage capacity that can continuously feed the loom for several hours or even days without interruption.
Speed and Tension Control:
The speed at which the loom weft accumulator feeds fabric is typically synchronized with the loom's weaving speed. This ensures a consistent supply of the weft yarn into the weaving shed. Additionally, the tension of the yarn or the woven fabric is crucial to maintaining the integrity of the fabric being woven. Weft accumulators are often equipped with devices to adjust and regulate the tension, ensuring that the loom operates smoothly and without breaks.
Power Supply:
Many modern loom weft accumulators utilize electric power for their drive systems. The operating voltage and current can vary according to the design specifications. For instance, an electric loom weft accumulator might work at 220V and have a 0.5kW motor.
Proper maintenance is crucial to ensure that the loom weft accumulator continues to perform its function efficiently and without any breakdowns. Here are some maintenance tips for a loom weft accumulator.
Regular Cleaning:
Cleans the accumulator to remove any fabric dust or debris that could affect the loom's weaving quality. Use a vacuum cleaner or a soft brush to clean all corners and surfaces of the accumulator.
Lubrication:
Regularly lubricate the moving parts of the loom weft accumulator, such as bearings and chains, etc. Lubrication can help reduce friction and wear, ensuring smooth operation.
Inspection:
Periodic inspection of the loom weft accumulator is essential to identify potential problems early. Check for signs of wear or damage to key components, such as chains, bearings, and tension devices. If any issues are discovered, they should be addressed promptly to avoid further deterioration and to prevent weaving interruptions.
Adjustment:
Based on the type of fabric being woven and the weaving tension required, the adjustments for the loom weft accumulator may be necessary periodically. This could involve changing the tension settings or the speed at which the accumulator feeds in the weft yarn.
Accumulating weft threads plays an essential role in various loom weaving applications. Here are some typical scenarios where loom weft accumulators are commonly used:
High-speed Loom Weaving
Weft accumulators are a common feature in high-speed looms, such as air-jet, rapier, and water-jet looms. Increased weft feeding tension may occur when loom weaving speeds exceed the normal feeding rates. Loom weft accumulators permit the shuttle to wait for the loom to complete its cycle before feeding in the next length of thread, thus preventing thread breaks and delays in production.
Weaving Complex Fabrics
When weaving complex or decorative patterns that require frequent changes of weft materials, loom weft accumulators are ideal. The loom can accumulate a sufficient length of the weft yarn for the insertion of the next thread without interrupting the weaving process. This leads to high-efficiency weaving operations.
Managing Yarn Tension
Yarn tension management is needed in various weaving operations. Loom weft accumulators can help maintain consistent weft tension during the insertion of the weft threads. They act as compensation mechanisms, allowing slight variations to occur in the loom's insertion rate. The loom can consistently insert the weft threads without excessive pulling or slack, which may adversely affect the fabric quality.
Cutting and Non-Cutting Loops
Loom weft accumulators are used in both cutting and non-cutting loop pile fabrics. Designing Weft Yarn tension in pile weaving designs is essential; therefore, loom weft accumulators facilitate the precise insertion of the weft threads. They help achieve the desired fabric characteristics and maintain the looping structure.
Long Production Runs
Long production runs require frequent weft replacements. Instead of stopping the loom to replenish the weft yarn, a loom weft accumulator can hold a length of the weft yarn, permitting the loom to continue running while the weft yarn is inserted at regular intervals.
Weft loom accumulators perform critical functions in textile production. Therefore, it is essential to choose them carefully to ensure smooth weaving processes. The following tips will help buyers pick the right loom weft accumulators.
Understand the Loom Design
Textile producers use different types of looms for weaving. While loom weft feeders generally perform the same function, their designs vary based on the loom type. Familiarity with the loom's structure will go a long way in choosing a suitable weft accumulator. For example, a jacquard loom weft accumulator may differ significantly from a plain weave loom weft feeder.
Determine Yarn Requirements
Yarn qualities differ depending on the material used. The texture, size, and tension requirements may also vary. While some weft accumulators are suitable for coarse yarns, others work better with fine yarns. Consider the yarn's characteristics when selecting a loom weft feeder. For example, the yarn may slip or break if the chosen accumulator doesn't match its texture and size.
Pay Attention to Compatibility
A loom weft accumulator may not fit well and work effectively if it isn't compatible with the existing machinery. Before buying a loom feeder, ensure it will integrate well with other equipment in the weaving setup. Check the dimensions, mounting systems, and feeding mechanisms to avoid costly adjustments and modifications.
Focus on Durability
Some woven fabrics undergo heavy usage and need to be very durable. Therefore, the loom weft feeder chosen should also be able to withstand frequent use and the wear and tear of its environment. Because textile production involves high costs, selecting a durable weft accumulator will help avoid replacement costs and production delays.
