TEXTURIZER MODEL 3SDX 3SDX
TEXTURIZER MODEL 3SDX The texturizer machine, model 3SDX, with double heater, produced and equipped to satisfy increasing requirements in the production of texturized yarn, with its complex of features and possibilities, represents a very advanced model. The quality of product, high productivity and efficiency, reliability and ability to manage it, and the contents costs are the characteristic features of this machine. The machine has a double front with its own commands, it is a feature considered as a significant advantage that allows to achieve big operative flexibility by working simultaneously with different parameters. The texturizer 3SDX is particularly adapted to texturize PES threads up to 330 dtex multi-yarn and micro-yarn and contains the base of three feeding shafts. The following main features:
THE COMMAND The computerized machine’s control system eliminates all turnings; single motors, regulated by inverters, control each shaft. COMPUTER The machine is provided with computerized operations’ management and control system. It is composed from a central unit which attains the connections of the various transducers of each single reading data position.
ENERGY SUPPLY Through three shafts with steel chrome-plated calandrine, the system with belts (casablancas type) provided with high capacity, auto-alignment, able to disconnect singularly for an easy manual insertion. HEATERS a) Texturizing heaters constituted from blocks with 6 threads; open to ceramics; warmed up by dowtherm fumes; each block has the probes allowing to control the temperature. b) Fixing heaters’ type – closed: operate for thermal transmission, warmed up with dowtherm fumes; built in mono-blocks with 12 threads per section.
The yarn passage tubes (ambù) can be taken out for a rapid periodic cleaning. The temperature is controlled by the probes. YARN COOLING The contact with a superficially hardened steel track, placed in the exit of the texturizing heater, makes the yarn cooled. FUMES ASPIRATION An effective aspiration system, placed at the entrance and exit of the texturizing heater, eliminates the fumes of combustion and the vapours of decomposition produced by yarn, contributing to maintain heater’s ceramics and cooling tracks cleaned.
SPINDLES The tangential belts, controlled by two asynchronous motors with inverter, transmit the movement; can be taken out individually and offer a variety of number and type of discs’ combinations. THE CONTROL OF YARN Electric sensors, connected to the respective cutters and optic signallers reporting the damage, control constantly each position of the yarn. TAKE UP Disposed on three floors; a single cam for each position, regulated by alternate current, drive each thread-guide zetto, All the parameters, characterizing the formation of a take up bobbin, such as electric troubles anti-pattern, angle crossing, anti-angle are inserted by central computer. Further mechanical order gears - inclination of the sides, compress’ strength and thread-guide track, that form the bobbin, complete the equipping of the individual positions. YARN OILING Yarn oilier is placed on each floor of take up. A reducing motor, that consents the variation of rotation speed , controls the oilier. SUPPORT OF POY Foreseen for each section of the machine, receives not only the feeding bobbins but including the transfer ones (reserve). Bobbins’ loading is much more easier exemplified with the self-centraled bobbins support.
