Abstract

PURPOSE:To effectively dehydrate woven fabric by passing the woven fabric woven with a water jet type loom through a spacing between a suction roller and a slit pipe while pressing the woven fabric to the suction roller additionally equipped with a cover composed of a water absorbing material in an outer cylindrical part. CONSTITUTION:A suction roller 2 prepared by rotatably assembling an outside pipe (2B) having many air-permeable holes in an inside pipe (2a) having many air-permeable holes connecting to a suction duct of a blower and simultaneously covering the outer cylindrical part thereof with a cover (2c) composed of a water absorbing material is arranged on the downstream side of a water jet type loom. Woven fabric (b) in a wet state woven with the water jet loom is introduced between the suction roller 2 and a slit pipe 3 and passed through a spacing therebetween while being pressed thereto. Thereby, water is sucked and removed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-machine dewatering device for woven cloth woven by a water jet loom.

[0002]

2. Description of the Related Art Conventionally, a woven cloth is made to pass through a slit-shaped long hole of a suction duct provided immediately after weaving, and air is sucked through the slit-shaped long hole so that the woven cloth is contained. Was removing water. However, since the woven cloth is pressed against the suction duct, the moisture is pushed out to the upper surface of the woven cloth, and only the water on the lower surface of the woven cloth, that is, the surface pressed against the suction duct is sucked, and sufficient dehydration can be performed. There were no drawbacks.

[0003]

According to the present invention, in order to remove water on the upper and lower surfaces of a woven fabric, a roll coated with a water-absorbing material is pressed against the upper face of the woven fabric and woven with a suction duct on the lower face of the woven fabric. A dewatering device is provided in which a cloth is sandwiched, the squeezed water is sucked, and the air inside the oar is sucked to collect the sucked water into the roll and discharge it to the outside through a pipe.

[0004]

EXAMPLE In FIG. 1, a warp yarn (a) is woven immediately after the reed (1) to form a woven fabric (b), which passes between a suction roll (2) and a slit pipe (3), and a pushing roll. (4) is sandwiched between take-up rolls (5) and sent out, and then wound up by take-up rolls (7) via pushing rolls (6). The suction roll (2) is connected to the blower (9) via a suction duct (8), and the slit pipe (3) is connected to the blower (9) via a blower duct (10).

In FIG. 2, the suction roll (2) is pressed against the upper surface of the wet woven cloth (b), and the slit pipe (3) is provided on the lower surface thereof. The woven cloth (b) is the suction roll (2) and the slit pipe. It is pressed against (3) and passes through. The suction roll (2) covers the cover (2c) using a water absorbent material,
And an outer pipe (2b) having a large number of ventilation holes and an inner pipe (2a) having a large number of ventilation holes, and the outer pipe (2b) is rotatably incorporated around the inner pipe (2a) as an axis, The inner pipe (2a) is fixedly installed on the main body of the loom.

Next, the operation will be described. In FIG. 3, the woven cloth (b) is pressed against the suction roll (2) and the slit pipe (3) to pass therethrough, and the squeezed water is absorbed by the cover (2c), and the vent hole of the outer pipe (2b). Through the ventilation holes of the inner pipe (2a) and collected inside and discharged. Since the outer pipe (2b) rotates according to the traveling speed of the woven fabric, the water absorbed by the cover (2c) collects in the inner pipe (2a) within the time from the first pressure contact to the next pressure contact. As long as it can be done, sufficient dehydration can be performed. By the way, the air sent from the blower (9) is introduced into the slit pipe (3) through the air duct (10) and heated by the pipe heater (12) assembled to the holding member (11). Then, the semi-dried woven fabric (b) after being squeezed by being ejected from the slit elongated hole (3a) is completely dried. In this example, the outer pipe (2b) was used to compensate for the insufficient strength of the cover (2c) made of a water absorbent material, but a material having both water absorbency and strength,
For example, if ceramics is used, the outer pipe (2b)
It is self-evident that is unnecessary.

[0007]

As described above, according to the present invention, since the water squeezed by the suction roll and the slit pipe is absorbed, a sufficient dehydrating effect can be exhibited.
