Product Description

GA169 serial sectional wrappers serve as fine and coarse wool fabrics, long chemical fiber filament fabric yarn yarn-dyeing, pure slid, towel and special in dustrial fabrics electional warping .The wrappers may match rapier and gripper, air-jet and water-jet looms as pre-weaving equipment, and are top-priority equipment for weaving mills to develop high-class and special kinds of fabrics and raise production and efficiency.

GA169 serial sectional wrappers have two types, GA169B and GA169C types. The beaming unit for GA169B wrapper is in stationery type, featuring compact structure and simple installation, and it can be equipped with two warping units, reducing investment. The GA169C wrapper is specially designed for fine wool fabrics with high configuration and strong functions, with double-disc noncolumn tensors in creel equipped.

MAIN FUNCTIONS AND TECHNICAL FEATURES

Mechanical, electrical. Pneumatic integration controlled by Siemens-made PLC, high performance and intelligentized operation.

Machine structures: he machine main body, warping unit, is mounted on rails, its movement is controlled by b servo motor, The beaming unit, leasing stand and creel are fixed one the ground. When warping, The strips are always kept in the central lines of the leasing stand and creel.

Warping drum and drive. The great steel drum with fixed-angle conic body is calibrated to b high dynamic balance precision, is driven by a motor by a AC frequency converter and rotates at a constant linear seed. The warping speed and a low speed are preset on the touching screen.

Slip displacement. The displacing device, driven by a AC digital servo driver, receive the digital signal from sensor on the touching screen. Synchronously with the drum movement, which features rapid response and high precision? Moreover, the servo drive instead of screw rod or gear drive directly drives the rollers, and keep from shake of the machine and facilitate the unit installment.

Constant distance winding. The warping table movement forward and backward is controlled by a step motor. While warping. The table move back at a mean speed, and the distance between guide roller and built-up yarn on the drum keeps constant, reliving strip diffusion and making the yarn sheet tension uniform.

Comb, The front comb is mounted on rails with side block, and its position can automatically be adjusted by a pneumatic cylinder, when warping, the comb is close to the guide roller to relieve strip diffusion. When the machine stops, the table moves back automatically and facilitates the following operation.

Warping brake, the pneumatic and hydraulic supercharging technology is sensitively braked by a clamping brake (when at 400m/min Warping speed, the braking distance is less that 3 meters), and made a broken end not wind into built-up yarn. So the efficiency and warp quality on drum is improved.

Beaming tension. The tension can be automatically controlled with damping type beaming. While beaming, the tension keeps constant or larger in inner layer or smaller in improved.

Beaming unit. The unit is wholly fixed on the ground, featuring less area covering and convenient operation.

Leasing comb. A3-point positioning totally-automatic leasing comb is equipped with the machine, yarn ends from creel is automatically leased.

Complete auxiliary functions. The waxing, pressing device against the loom beam (selective) and static eliminator are available.

Electric unit and key components: All electric and pneumatic elements in the unit are selected from international reputed bands, and are reliable in quality.

Complete error detection system, Errors occurring at the operating machine can be detected at any minute, including mistake operation, position-limited protection and the computer run. The detected date is displayed in Chinese and in English to be easy to maintenance.

A great touching type display screen is equipped to set and control various technological parameters, featuring convenient and good visualization.
