  • the raw material is subjected to several processes.
  • One of these processes is a hot drawing process.
  • the hot drawing process is performed to make the yarn had necessary elongation and strength for producing a textile product.
  • a roller/galette is heated by means of a heater and rotated around an axis. When the roller reaches the necessary temperature, the semi-finished yarn is wound around the heated roller and drawn.
  • heating is performed with heated oil and this can cause cleaning problems.
  • convectional heating of the roller by a heating element is preferred.
  • the heating element is also rotated with the roller and this cause vibration of the heating element. This vibration situation makes the heating element nondurable and for that reason maintenance costs increase. Furthermore, due to vibration, obtaining a uniform temperature on the roller is getting difficult.
  • a hot drawing apparatus for yarn production is developed by the present invention.
  • the hot drawing apparatus of the present invention is suitable for use in the yarn production processes in order to make the yarn has necessary elongation, strength and durability.
  • the apparatus comprises at least one roller (1 ), which is in the form of a hollow cylinder which is provided such that it is able to rotate around an axis (this axis is preferably passing through the center of the roller), and which comprises at least one body (2) made from heat conducting material, preferably metal, at least one first opening on at least one side and at least one second opening on at least one other side; at least one heating member (3) which is provided in the roller (1 ) by passing through the first opening, preferably with a distance to the inside surface of the roller (1 ) and which preferably has a length such that when the heating member (3) is reached the maximum temperature, the elongation of the heating member (3) due to the temperature rise should not cause the heating member (3) to touch the roller (1 ) from inside; at least one movement element (such as motor) (not shown in the figure)

Therefore, also the holding element (14) is placed in the casing (1 1 ) and fixed to the support block (12) by means of a connection element such as screw, bolt etc.. Since the transmission element (7) is in connection with the roller (1 ) from one side and with the casing (1 1 ) from the other side, by rotating of the transmission element (7) around an axis (preferably coinciding to the rotation axis of the roller (1 )) by means of the movement element, the casing (1 1 ) and the roller (1 ) also start to rotate.

Thanks to the bearing (10), rotation of the casing (1 1 ) with respect to the support block (12) is ensured and casing (1 1 ) is supported during rotation without touching to the holding element (14). Thanks to the hot drawing apparatus of the present invention, rotation of the roller (1 ) by keeping the heating member (3) stationary is ensured and therefore, vibrating of the heating member (3) due to rotation is able to be eliminated. Therefore, maintenance costs decrease and long lasting hot drawing apparatus is obtained.
  • the apparatus further comprises at least one insulation member provided between the heating member (3) and the holding element (14), preventing the heat transmission from heating member (3) to the transmission element (7) and holding element (14).

  • the insulation member is preferably made from ceramic fiber.
  • the apparatus preferably comprises a dark coating which is provided inside surface of the body (2) of the roller (1 ) and which is in the frequency range of the radiated heat from the heating member (3).
