Selvedge curls are smoothed perfectly using Tandematic brand selvedge expanders and fabric is passed through the pins using Microtech brand selvedge control photocells. The fabric is fully settled on the pins by selvedge reinforcement brushes. Using a rack head traversing system, rapid and reliable processing of fabrics is accomplished.
By passing the fabric through a steamer unit before entering the chambers a better touch and effect is obtained. An air fanned steam screening system is used for protecting the electric circuits and motors from the steam.
A conveyor system with circular belts is located at the chain entrance unit that functions synchronously with the upper feeding roller and carries the center of the fabric to the chambers during ample feeding instances.
Knitted fabrics are prepared for selvedge cutting process by first passing them thorough a starching unit by means of a selvedge starching wheel. The starched fabric selvedges are dried by using LEITER brand selvedge dryers. Using these devices, the temperature can be increased up to 700 °C without changing the speed of the machine.
The chain rails are imported from abroad and are made from durable metal casting. A horizontal chain system is used which has the capability of increasing the endurance of the machine. With the horizontal chain system, very thick woven fabrics can be processed securely at the desired tension.
Chain lubrication can be done manually or automatically by adjusting the speed of the chain. CHAMBERS:
Special chamber construction is possible if fast transportation and mounting is needed. Chambers are manufactured with lengths of 3 metres at any width based on customer requirements. The lower, upper and side walls of chambers are insulated with rock wool panels that have very low heat transfer coefficients and heat resistances of 700 °C. Entry and exit chambers are equipped with inclined spinneret system for preventing condensation and dripping. This system generates an air screen at the entry and exits of the chambers which increases the performance of the machine. The entry and exit chambers are also equipped with rail bellows that open together with chains. All the sheets inside the chambers are galvanized. Black color material has not been used in any part of the machine that is viable to rusting. By this way, the lifetime of the machine has been increased.
Each chamber is equipped with a symmetric spinneret and fan system for preventing fabrics from having differences in colors and panels. Special design overcomes static pressure at the tips of the spinnerets. Uniform air circulation has been established in the chamber by increasing the speed of hot air while passing through narrowed spinneret tips. Furthermore, the wings on spinnerets directs the hot air flow towards the fabric. Lower and upper spinneret hole axes have an asymmetrical design which gives the fabric an ideal touch and effect.
The air heating up inside hot oil serpentines or gas burning sections of chambers is absorbed from canals through fans and delivered into the spinneret holes and then directed towards the fabric. The volume and speed of hot air passing through spinnerets are adjusted automatically by the invertors that controls the fan motors. Furthermore, it is also possible to adjust the volume of hot air passing from lower and upper spinnerets through the spinneret brims.
