Specifications: Product Description GA293 Pirn Winding Machine, also called yarn winding machine, yarn spooling machine, or yarn twining machine, is a kind of yarn winding machine used in the preparatory step in shuttle weaving and tatting industry to roll or wind the bobbin yarn into woof yarn for weaving. Model GA293 vertical weft winding machine is suitable for winding different yarns (silk threads) such as pure cotton, trueran, ramie, low elasticity filament, mid fibre, etc.. it is an export special-purpose machine. This machine is improved from SG193 and G203 models. It is developed to overcome the shortcomings of SG193 and G203 such as weft's high omission rate, bad tatting efficiency, wasting labor, energy, and materials, and high maintenance and repair cost. While this improved machine can not only effectively control the weft omission but also increase the scope and kinds of yarns that are suitable for weaving. Furthermore, it realizes the energy-saving, labor-saving, and consumption-decreasing. The SG193 and G203 models can be rebuilt by changing the headstocks. specifications︰ 60 spindles~316 spindles(basic: 60 spindles). Standard: 156 spindles Advantages︰ The weft missing is completely removed away. Principle: Abolish all complicated and easy workout gears transmission. The worm gear pair directly drives the cam. And adopt 1:1 forming cam curve, Increase the winding screw-pitch to 1.2mm. the large screw-pitch and the net-shaped winding effectively control the weft missing. The energy-saving and efficiency-increasing rate reaches to more than 50%. Also save the land occupation area. Principle: Design the spindle speed to be 3500r.p.m to the most. The time for the bobbin to be full is only half of that of the old model. Its production efficiency can improve by half. The motor's energy consumption thus is reduced by 50%. Very convenient and easy in changing yarn's kinds. Wide yarn scope. Principle: With the consideration of all related factors in design. The changing of yarns is realized by adjusting the ratchet wheel's bracing teeth. The winding scope is enlarged to 3SW-100SW. Simple headstock, large space, complete functions, low trouble rate. Principle: Abolish all the gear transmissions. The machine runs smoothly and reliably with low noise. The doors on the headstock cabinet are open in three sides. Large space. Wires and switches are built-in. Users can install daylight lamps at each section according to their needs. The electric appliances cabinet's door is installed with a switch that is with a lock for the convenience of users. Smooth and stable yarn guide. Good shaping. Principle: Abolish the gear transmission. The yarn guide plate moves up and down smoothly. There is no overlapping of winding. And the 1:1 cam moves up and down evenly. Good large screw-pitch winding and shaping quality. No damage to the main shaft. Principle: The motor drives the belt pulley to directly drive the main shaft. And when The machine is started it is under the overload-protection. So even the machine runs for a long time the main shaft wilt not be damaged. The whole machine adopts the imported electrostatic plastic spray technique to achieve a clean, tidy, and beautiful outlook. Principle: The machine bed adopts the imported electrostatic plastic spray technique to make the accuracy of the machine and the outlook of it reach to the imported machine's level.
