Staubli Dobby Parts

Product Details:

Dobby Magnet Bar 20Shaft suitable for all Staubli Dobby 2668,2660,2650,2622,2670.   

Dobbr Magnet Bar Suitable For 12 Shaft /16 Shaft/ 20 Shaft .

A 20-shaft dobby magnet bar is a spare part for weaving machines, specifically designed for Staubli dobby machines and related models like 2668, 2660, 2650, 2622, and 2670. It's typically made of mild steel. This component plays a crucial role in controlling the pattern of woven fabrics by lifting and lowering individual shafts, which in turn affects the position of the warp threads. The 20-shaft designation indicates the number of shafts the dobby mechanism can control.

The F294.912.51 Dobby Levelling Sensor is an electric sensor used in the textile industry as a spare part for Staubli dobby weaving machines. Its primary function is to detect and correct the positioning of the dobby mechanism during weaving. Product description

• Model Number: F294.912.51.
• Purpose: Leveling sensor for the dobby mechanism.
• Power Source: Electric.
• Size: The cable is approximately 1.5 meters in length.
• Packaging: Typically sold in a box.
• Weight: Approximately 50 grams.
• Compatibility: Designed for use with Staubli dobby machines. 

ApplicationThe sensor is a crucial component within the textile weaving industry, specifically for automated looms that use a dobby shedding mechanism. 

• Dobby mechanism: A dobby is a device that controls the lifting of the warp threads to create patterns in a woven fabric. It allows for the production of more complex patterns than basic looms can achieve.
• Automatic control: The F294.912.51 sensor ensures the precise and consistent "levelling" or positioning of the dobby mechanism as it operates. This constant feedback helps maintain the accuracy of the weaving pattern.
• Quality control: By ensuring correct positioning, the sensor prevents weaving errors and helps produce high-quality fabric. A malfunction in this sensor could lead to defects in the finished textile.

Staubli Dobby Selectors For the Staubli Dobby Model 2660/2670.

A dobby selector is a component in weaving looms, specifically those with a dobby shedding mechanism, that is used to select and raise individual healds (or shafts) to create different weaving patterns. It acts as a control mechanism, enabling the loom to produce a variety of textures and patterns beyond the limitations of a basic handloom. Elaboration:

 

• Function:Dobby selectors are crucial for creating more complex patterns than a basic handloom can achieve. They allow for the selective lifting and lowering of healds, which in turn control the warp threads and create the desired weave. 
• Mechanism:In a dobby loom, a series of selectors are connected to electromagnets or mechanical linkages (like cams or levers) that are activated by a control system (e.g., punched cards, computer programs). When a selector is activated, it lifts the corresponding heald, creating the necessary shed for the weft thread to be passed through. 
• Types:Dobby selectors can be found in various forms, including:
  • Manual: Operated by hand, using levers or treadles to lift the healds. 
  • Mechanical: Using cams or tappets to control the movement of the selectors. 
  • Electronic: Controlled by an electronic system and activated by solenoids or other electric devices. 
• Applications:Dobby selectors are commonly used in:
  • Rapier looms: For controlling the shedding mechanism. 
  • Airjet looms: Where the loom uses compressed air to propel the weft carrier. 
  • Other textile machinery: Where more complex patterns are desired beyond those achievable with a basic handloom.
