Jacquard weaving solutions:
The world of Stäubli jacquard machines is a fascinating one, in the entire world; countless weaving mills produce innovative high-quality fabrics with these reliable and multipurpose machines. The variety of ranges from the finest silks to the most complex technical textiles and original decorative fabrics. Stäubli electronic control is high-performance machines, beneﬁting from many years of technical experience. They are distinguished by their high Performance characteristics, the quality of the materials used and their impressive service life. Stäubli Jacquard machines represent a complete range of formats, ranging from 32 to 24576 hooks for producing all types of fabric. know-how to all weaving mills, at the international level .
Exacting requirements and high-performance:
Shedding machines guarantee optimal performance and portability. They perfectly fulfill weaving machine and shed forming requirements, geometries, openings and adjustments are almost unlimited. Weave medications are extremely ﬂexible and can be changed rapidly.With a cam motion, a dobby or Jacquard machine, Stäubli systems allow you to get the most out of weaving machines owing to transmission systems, quick frame connects or through a custom made harness or carbon ﬁbre frames. Stäubli attaches major importance to the reliability and user friendliness of its shed forming machines
Basic construction features of Stäubli Jacquard:
The DX 100 and DX 110 are delivered with the adaptation elements required for each type of weaving machine pre-installed . The transmission is based on a cardan drive with bevel gears, whose position is determined according to the weaving machine to optimize the cardan shaft angle . For wide microprocesred spaces, the optional addition of a modulator accelerates shed opening . The compact structure of DX 100 and DX 110 machines enables them to be used on standard frames and in low ceiling weaving rooms.
Each machine has its own electrical power supply and is equipped with an electronic controller and is equipped with a JC6 electronic controller with touch screen. This user-friendly interface between the user and the DX features the latest generation of microprocessor. A flash disk advantageously replaces hard drive technology and patterns can be transferred either via USB key, external drive or the network. The latter offers multiple possibilities and facilitates weaving room management or several remote sites.
T H E M6 MODULE
The patented M6 module ensures the connection between the lifting mechanism and the harness. Compact, and engineered from composite materials, the M6 module is sealed and wear resistant and consumes very little energy.
If required, depending on the loads and speeds in use, M6 module can be equipped with two journal bearings (version A), one journal bearing at the bottom and a ball bearing (C) on the top or with two ball bearings (B) . Module replacement is easy and quick .
The rollers built into the module make hooking and unhooking the harness cords easy – the system is also available with QUICK LINK.
SELECTING HOOKS IN A MODULE
The double roller enables the upper and lower shed position of the harness cords in double lift.
Low shed position
The electromagnet (f) is activated. The retaining hook (c) does not retain the mobile hook (a) which follows the lowering knife (e).
Upper shed position
The electromagnet (f) is not activated. The retaining hook (c) retains the mobile hook (a).
Low shed Upper shed
The kinematics of Stäubli Jacquard machines is characterised by:
· Controlled by a single cam housing running in an oil bath
· An extremely simpliﬁed transmission via a coaxial shaft system
· Perfect mass balance of the moving parts for optimally smooth running
· Simple and fast adjustment of lift and inclined shed
The QUICK LINK connection system was developed for speedy hooking and unhooking of the harness cord.
Quick link connection Harness BLOBAR automatic blowing
Developed thanks to Stäubli’s know-how, our harnesses are designed for all applications: labels, silk goods, lining, clothing, upholstery fabrics, table and bed linen, automotive seats, airbags, bedspreads, terry cloth and pile fabric . Our harness specialists have developed a line of harness cords, heddles and springs depending on the article, the characteristics of the warp yarn and the weaving conditions.
The comber boards are made and drilled to customer specifications. The links between the harness cords and the heddles, the heddles and the springs are designed to meet all your needs.
BLOBAR BLOWING SYSTEM
Designed to facilitate the cleaning of harness springs, Stäubli developed the BLOBAR automatic blowing system, at the back of the down pull frame. The pneumatic blowing device limits fl y deposit and facilitates manual cleaning.
The Formation of Woven Velour by Jacquard
Velour – “From the Latin vellosus, meaning hairy. The material is a thick bodied, close napped, soft type of cloth. Generally speaking, a velour is a cloth that runs from 10 to 20 ounces per yard, and is given a face finish”
Where we found Velour fabrics?
Woven velvets and velours can be found in every textile market: Apparel, Automotive, Home Furnishing, Contract Upholstery, Transportation and Industrial/Specialty Fabrics. Each use is represented by a uniquely constructed product depending upon the cost, aesthetics, and performance expectations of the customers. The two largest markets for this product are Automotives and Home Furnishings.
How to form?
Although there are other ways of forming a velour fabric such as the wire method, primary focus will be on the production of current transportation velour. The method of choice for producing velour today is to use a double insertion rapier machine.
The shedding motion is usually controlled either by jacquard head. The pile warp yarn is either pulled (jacquard) into the fell of the fabric.
The sandwich structure is made by the interlacing of the pile warp yarns between the picks of the top and bottom pieces of fabric.
