Description

CALENDER MACHINE WITH RUBBER

BLANKET This invention is about calender machine with rubber blanket (14), which allows the fabric to pass through the calender cylinders, between the rubber blanket with court fabric and the chrome-coated cylinder to which this blanket is wrapped, creating different touchings on the fabric during the calendering process in the textile sector after paint

finishing process.

In the textile sector, calender machines can adjust the brightness and touching of fabrics in certain proportions. For this reason, fabrics are calendered and some types of fabric are then

subjected to sanforizing.

In the known case of the technique, calender machines are composed of three types of cylinders. In these systems, at least one of the cylinders can be heated and chrome coated. The other cylinders are produced with a mixture of polyamid coated and composed of cotton fibers and / or other additives.

The fabric is passed through hot and cold chrome-coated cylinders and other cylinders. The cylinders are pressed together with a maximum linear force of 300 kg/cm. When the fabric is under the influence of pressure and temperature, the speed of the machine and the touching of the fabric is changed.

In the known case of the technique, the process following this is sanforizing. In sanforizing machines, they use rubber with a hardness of about 40 shA and without court fabric reinforcement. This rubber is pressed onto the cylinder, which warms up to 120 °C. The fabric is passed through the rubber and cylinder, and the touching is changed.

In the known case of the technique, some fabrics in the textile industry require excessive brightness. For this reason, the fabrics are passed through the calender machine at a high temperature and pressure. The desired brightness is achieved, but during this process the fabric hardens. This is not a desired result. In order to change this result, it is subjected to

sanforizing process and passed through sanforizing machine. The hardness of the fabric is tried to be reduced. This process requires the two processes to follow each other and this causes time and cost to the producer. The temperature limit for sanforizing machines is 120°C. Higher temperatures cannot be used.

In the known case of the technique, the textile finishing sector is a whole of processes that make up the ornamentation, quality and market of the fabric. It is one of the most important items in terms of saving cost and time in this area. This stage is one of the defining elements for the quality of the fabric

and it is a part that requires meticulousness since repeated processes cause deformations. For this reason, it is desirable to avoid this kind of work in the production sector or it is planned to work within certain limits. In this case it constitutes a limiting effect. Purpose Of Invention

The invention different in the textile industry after paint finishing processes. The purpose of the invention; to create different touchings

on the fabric. The invention is about adding a special rubber blanket to the calender machines currently used. The fabric passing through the calender cylinders passes between the rubber blanket with court fabric and the chrome-coated cylinder in which the blanket is wrapped. In the meantime, the blanket is stretched

and the fabric is pressed between the blanket and the cylinder.

In rubber blanket unit (17) there is an eccentric cylinder (2) mounted on the chassis (1 ). The depressor arms (5) are mounted on the shafts of this cylinder. There are idle cylinders (6) at the ends of the depressor arms(5). There are rubber blankets (14) on the idle cylinders(6) and the eccentric cylinder (2). The hydraulic pistons (8) are connected to the arms on the eccentric shafts. These pistons are also mounted on distance profiles (15), which are connected to the machine body.

When the rubber blanket system is inactive, the hydraulic pistons (8) pull up the handles and drift apart the rubber blanket (14) from the chrome- coated cylinder.

After the first installation of the system, the necessary adjustments are made. By operating the hydraulic unit (7), the rubber blanket (14) is pressed

onto the chrome cylinder through hydraulic pistons (8). The eccentric cylinder (2) is brought to the lowest position. The arms are lowered until they are fitted to the centering system (11) (12). In this position, the system is locked. The tension of the rubber blanket (14) is increased by using the manual blanket tensioning system (9). It is brought to the desired setting with the blanket tension measurement system (10). This position

is the position at which the rubber blanket (14) is stretched to a minimum. The tension of the rubber blanket (14) can be changed automatically by changing the position of the eccentric cylinder (2). The tension can be increased and reduced according to the fabric type and the desired touching.

Rubber blanket (14) twits and turns during operation. Rubber blankent's (14) continuous movement to the same direction creates a problem. At the edges of the idle tube of the eccentric cylinder (2), there are projecting flanges to support the blanket. When the rubber blanket (14) goes in one direction it leans on this flange. There are 4 blanket edge control photocells (16) mounted on the distance pipe located between the arms. 2 of these photocells (16) are placed on the right side of the rubber blanket (14) and the 2 of them are placed on the left side. The photocells (16)

close to the rubber blanket (14) receive the information on which side the rubber blanket (14) goes and send it to the PLC. With this information, rubber blanket (14) activates the centerin system. Thus, the rubber blanket (14) moves to the opposite direction. The photocells (16) away from the rubber blanket (14) are the border photocells. When these photocells (16) are active for a certain time, the machine makes an emergency stop and the rubber blanket (14) is separated from the chrome-coated cylinder.

With our invention, a rubber blanket with court fabric reinforced was mounted on the calender machine which is already used. In this way, it is provided to obtain different touchings from the calender machine. Hardening occurs especially in fabrics calendered with high temperature. It provides a very different touching by passing through the rubber blanket and the chrome-coated cylinder immediately after passing through the fabric calender cylinders. By means of the

court fabric in the rubber blanket, the blanket tension has been increased by 3 times compared to the sanforizing machines. In this way, the fabric is exposed to higher force between the cylinder and the blanket. In addition, instead of the rubber that can work up to 120 ° C in sanforizing machines, a special rubber that can work up to 160 ° C is used. In this way, we allowed fabric to pass at higher temperatures. It is foreseen to get better touching by passing some fabrics through only blanket calender machine, instead of passing them fabrics through calender and sanforizing machines. It is possible to obtain a new touching by simply passing some fabrics between the chrome-coated cylinder and the rubber blanket without using calender cylinders. In the known case of the technique, while calendered fabrics shine, they also harden depending on the type of fabric. This is undesirable by the manufacturer. When the fabric passed through the rubber blanket calender machine enters the rubber blanket after the calender cylinder, the hardness caused by the calender (although it varies according to the fabric type) is largely eliminated.

With our invention, different touchings can be obtained by passing the fabric at higher temperatures than the temperature in sanforizing.

With our invention, the hardness of the fabric is reduced by passing the calendered fabric through the blanket.

With our invention, there is no need for the sanforizing process needed in some fabrics.
